1 Introduction
Logic Analyzer Description The Agilent Technologies 1660A Series Logic Analyzers are part of a new generation of general-purpose logic analyzers. The 1660A Series consists of five different models ranging in channel width from 34 channels to 136 channels. State speed is either 50-MHz or 100-MHz (depending on the model), and all models have 500-MHz timing speeds.
Introduction The 500-MHz timing analyzer has conventional, transitional, and glitch timing modes with variable width, depth, and speed selections. Sequential triggering uses 10 sequence levels with two-way branching, 10 pattern resource terms, 2 range terms, 2 edge terms and 2 timers.
Introduction User Interface User Interface The 1660 Series analyzers have several easy-to-use user interface devices: the knob, the front panel arrow keys and keypad, the mouse, and the optional keyboard. Front panel arrow keys move the highlighter to identify the desired field, then a front panel Select key is pressed to activate the field. The knob quickly moves the highlighter (cursor) in certain menus to highlight options to select and to quickly change numeric assignment fields.
Introduction Configuration Capabilities Configuration Capabilities The five analyzer models in the 1660 Series offer a wide variety of channel widths and memory depth combinations. The number of data channels range from 34 channels with the 1664A, up to 136 channels with the 1660A. In addition, a half channel acquisition mode is available which doubles memory depth from 4 Kbytes to 8 Kbytes per channel while reducing channel width by half.

2 Probing
Probing This chapter contains a description of the probing system for the logic analyzer. It also contains the information you need for connecting the probe system components to each other, to the logic analyzer, and to the system under test. Probing Options You can connect the logic analyzer to your system under test in one of the following ways: • • • • Agilent Technologies 10320C User-Definable Interface (optional). Microprocessor and bus specific interfaces (optional).
Probing Microprocessor and Bus Specific Interfaces There are a number of microprocessor and bus specific interfaces available as optional accessories that are listed in the Accessories for Agilent Logic Analyzers. Microprocessors are supported by Universal Interfaces or Preprocessor Interfaces, or in some cases, both. Universal Interfaces are aimed at initial hardware turn-on, and will provide fast, reliable, and convenient connections to the microprocessor system.
Probing The termination adapter is designed to connect to a 20 (2x10) position, 4-wall, low-profile, header connector which is a 3M-Series 3592 or equivalent.
Probing General-Purpose Probing System Description General-Purpose Probing System Description The standard probing system provided with the logic analyzer consists of a probe tip assembly, probe cable, and grabbers. Because of the passive design of the probes, there are no active circuits at the outer end of the cable. The rest of this chapter is dedicated to general-purpose probing. The passive probing system is similar to the probing system used with high-frequency oscilloscopes.
Probing General-Purpose Probing System Description Probe and Pod Grounding Each pod is grounded by a long, black, pod ground lead. You can connect the ground lead directly to a ground pin on your target system or use a grabber. To connect the ground lead to grounded pins on your target system, you must use 0.63-mm (0.025-in) square pins, or use round pins with a diameter of 0.66 mm (0.026 in) to 0.84 mm (0.033 in). The pod ground lead must always be used.
Probing General-Purpose Probing System Description Grabbers The grabbers have a small hook that fits around the IC pins and component leads. The grabbers have been designed to fit on adjacent IC pins on either through hole or surface mount components with lead spacing greater than or equal to 0.050 inches. Probe Cable The probe cable contains 18 signal lines, 17 chassis ground lines and two power lines for preprocessor use. The cables are woven together into a flat ribbon that is 4.5 feet long.
Probing Assembling the Probing System Assembling the Probing System The general-purpose probing system components are assembled as shown to make a connection between the measured signal line and the pods displayed in the Format menu.
Probing Assembling the Probing System Connecting Probe Cables to the Logic Analyzer All probe cables are installed at the factory. If you need to replace a probe cable, refer to the Service Guide that is supplied with the logic analyzer. Connecting the Probe Tip Assembly to the Probe Cable To connect a probe tip assembly to a cable, align the key on the cable connector with the slot on the probe housing and press them together.
Probing Assembling the Probing System Disconnecting Probe Leads from Probe Tip Assemblies When you receive the logic analyzer, the probe leads are already installed in the probe tip assemblies. To keep unused probe leads out of your way during a measurement, you can disconnect them from the pod. To disconnect a probe, insert the tip of a ball-point pen into the latch opening. Push on the latch while gently pulling the probe out of the pod connector as shown in the figure.
Probing Assembling the Probing System Connecting the Grabbers to the Probes Connect the grabbers to the probe leads by slipping the connector at the end of the probe onto the recessed pin located in the side of the grabber. If you need to use grabbers for either the pod or the probe grounds, connect the grabbers to the ground leads in the same manner. Connecting Grabbers to Probes Connecting the Grabbers to the Test Points The grabbers have a hook that fits around the IC pins and component leads.

9 The Common Menu Fields
The Common Menu Fields There are a number of fields that appear throughout the different menus that have similar operation. These common fields are listed below: • • • • • • • System/Analyzer field Menu field Print field Run field Base field Label field Label and Base roll field If there is any unique operation with any of these common fields in a particular menu, supplemental information is given in that menu. In all other cases of common operation, you are referred back to this section.
The Common Menu Fields Common Menu Fields Menu Map The Common Menu Fields menu map contains fields that appear in most, if not all, main menus. When these fields are discussed in other chapters, you will be referred back to this chapter and this menu map. This menu map will help you get an overview as well as provide you with a quick reference of what the common menu fields are.
The Common Menu Fields System/Analyzer Field System/Analyzer Field The System/Analyzer field is always located in the upper-left corner of all main menus. If you have accessed any of the System configuration menus, this field displays "System." If you have accessed any of the analyzers configuration menus, this field displays "Analyzer.
The Common Menu Fields Menu Field Menu Field The Menu field is always the second field from the left, in the top row of fields. The Menu field identifies the System or Analyzer menu you are in, and you use it to access the other analyzer menus. When a new menu is selected from the menu selection pop-up, the new menu appears and the name in the Menu field changes to the name of the new menu.
The Common Menu Fields Print Field Print Field The Print field allows you to print what is displayed on the screen at the time you initiate the printout. When you select the Print field, a print selection pop-up appears showing you one or more of the following options: • • • • • Cancel Print Screen Print All Print Partial Print Disk When you select one of the print options, the information in the display is frozen; then, the Print field changes to Cancel.
The Common Menu Fields Print Field Print All The Print All option prints not only what data is displayed on the screen, but data that is below the screen in the Listing, Trace, and Compare menus. When you select the Print All option, the message "Printing All" appears at the top of the display. This message will not appear in your printout. When you select Print All, make sure the first line you wish to print is in the state location box at the center of the listing area.
The Common Menu Fields Print Field Print Disk The Print Disk option is very useful if you want to copy the measurement data in ASCII form to a DOS formatted disk in the disk drive. This operation is similar to the Print All option except the destination for the data is the disk instead of a graphics printer. Once the data is on a DOS disk, the data can be loaded into a computer.
The Common Menu Fields Run/Stop Field Run/Stop Field The Run field starts the analyzer measurement. When Run is selected, the acquired data is displayed in the last measurement display menu accessed. If Stop is selected during a single run, the data acquisition is aborted. During a repetitive run, when Stop is selected after the first run cycle, the present single run cycle is completed before data is displayed. Single The Single option runs the data acquisition cycle one time.
The Common Menu Fields Base Field Base Field The numeric base for displayed data under each label is set by the Base field. All assigned labels will have a Base field assigned to it. If the numeric base is changed in a menu, the base in other menus may not change accordingly. As an example, the base assigned to symbols is unique, as is the base assigned in the Compare and Listing menus, so you would not want them to change.
The Common Menu Fields Label Field Label Field New label assignments and existing label name changes are done only in the Format menu. However, you can insert, delete, replace, or interleave labels in other menus where assigned labels appear. When you select a label field, a list of label actions appear. Insert The Insert option accesses a selection list of assigned labels. The label selected from this list is inserted to the right of the label used to start the label action.
The Common Menu Fields Label Field Interleave With two state analyzers configured, and the Count fields in the respective Trigger menus set to Time, the Interleave option becomes available. The Interleave option allows you to interleave two labels and their data from the two different analyzers in the same column. The interleaved label is placed directly above the selected label and all interleaved data is displayed in white. In addition, the state numbers of the interleaved data are indented to the right.
The Common Menu Fields Label / Base Roll Field Label / Base Roll Field When the number of assigned labels becomes greater than the total number of labels that can be displayed on screen, the analyzer will store them off screen. If there are offscreen labels, the Label/Base roll field turns dark. To roll label and base fields onto the screen, activate the roll function by selecting the dark Label/Base roll field.

10 The Configuration Menu
The Configuration Menu The Configuration menu is one of the analyzer menus that allows you to set analyzer level parameters. For example, in the Configuration menu the pod pair assignments are made. In addition, the type of clocking is selected and a custom analyzer name can be assigned. Configuration Menu Map The following menu map illustrates all fields and the available options in the Configuration menu.
The Configuration Menu Name Field Name Field The Name field allows you to assign a specific name to the analyzer. The name is entered by using the front-panel alpha keypad or the optional keyboard. Simply highlight the Name field and type the new name. When configurations are stored to disk and later reloaded, a specific name can help identify the measurement setup.
The Configuration Menu Type Field Type Field The Type field allows you to configure the logic analyzer with either an external clock or an internal clock. When the Type field is selected, the following choices are available. Timing When Timing is selected, the analyzer uses its own internal clock to clock measurement data into the acquisition memory. This clock is asynchronous to the signals in the target system.
The Configuration Menu Unassigned Pods List Unassigned Pods List The list of Unassigned Pods in the Configuration menu shows the available pods for the analyzer configuration. Pod grouping and assignment is by pod pairs. When a pod pair is selected from the Unassigned Pods list, an assignment menu appears. From the assignment menu, select a destination for the pod pair. Within each pod pair, activity indicators show the integrity of the connected signals. See Also "Activity Indicators" in this chapter.
The Configuration Menu Unassigned Pods List Illegal Configuration When both analyzers are turned on, the first pod pair 1,2 and the last pod pair (5,6 in the 96 channel model or 7,8 in the 128 channel model) cannot be assigned to the same analyzer machine. If this configuration is set, the analyzer will display a reassignment menu. Use this reassignment menu to configure the pod assignment automatically to a legal configuration.
The Configuration Menu Activity Indicators Activity Indicators A portion of the Configuration menu that is not a selectable field is the Activity Indicators. The indicators appear in two places. One is in the pod pair displays of this Configuration menu. The other place is in the bit reference line in the Format menu just above the pod bit numbers.
The Configuration Menu System / Analyzer Field System / Analyzer Field The function of the System/Analyzer field is the same in all menus. For a complete definition of the System/Analyzer field, go to "The Common Menu Fields" chapter at the beginning of the Analyzer part of this User’s Reference. Menu Field The function of the Menu field is the same in all menus.
11 The Format Menu
The Format Menu The Format menu is where you assign which data channels are measured and what acquisition mode is used to capture valid data. The configuration of the Format menu consists of grouping and labeling the data channels from the system under test to fit your particular measurement. For your convenience in recognizing bit groupings, you can specify symbols to represent them.
The Format Menu Format Menu Map 11–3
The Format Menu State Acquisition Mode Field (State only) State Acquisition Mode Field (State only) The State Acquisition Mode field identifies the channel width and memory depth of the selected acquisition mode. When the State Acquisition Mode field is selected, two configurations of channel width/memory depth become available. Use the State Acquisition Mode to configure the analyzer for the best use of available memory and channel width.
The Format Menu Timing Acquisition Mode Field (Timing only) Timing Acquisition Mode Field (Timing only) The Timing Acquisition Mode field displays the acquisition type, the channel width, and sampling speed of the present acquisition mode. The Timing Acquisition Mode field is used to access an acquisition mode selection menu. Conventional Acquisition Mode In Conventional Acquisition Mode the analyzer stores measurement data at each sampling interval.
The Format Menu Timing Acquisition Mode Field (Timing only) Transitional Acquisition Mode In Transitional acquisition mode, the timing analyzer samples data at regular intervals, but only stores data when there is a level transition on currently assigned bits of a pod pair. Each time a level transition occurs on any of the bits, all bits of the pod pair are stored. A time tag is stored with each stored data sample so the measurement can be reconstructed and displayed later.
The Format Menu Timing Acquisition Mode Field (Timing only) Timing acquisition mode field Acquisition mode selection menu Timing Acquisition Mode Selection Transitional Full Channel 125 MHz Mode The total memory depth is 4 Kbytes per channel with a channel width of 34 channels per pod pair. Data is sampled for new transitions every 8 ns. When the Timing analyzer runs in the 125 MHz mode, it operates very similar to the State analyzer with count Time turned on.
The Format Menu Timing Acquisition Mode Field (Timing only) Minimum Transitions Stored Normally, transitions occur at a relatively slow rate. A rate slow enough to insure at least one sample with no transitions between the samples with transitions. This is illustrated below with time-tags 2, 5, 7, and 14. When transitions happen at this rate, two cycles are stored for every transition. This means that with 2 Kbytes of memory, 1 Kbytes of transitions are stored.
The Format Menu Timing Acquisition Mode Field (Timing only) Transitional Half Channel 250 MHz Mode The total memory depth is 8 Kbytes with a channel width of 17 channels on one pod. The pod used within the pod pair is selectable. Data is sampled for new transitions every 4 ns. Transitional timing running at 250 MHz is the same as the 125 MHz mode, except that two single pod data samples (17 bits x 2 = 34 bits) are stored instead of one full pod pair data sample (34 bits).
The Format Menu Timing Acquisition Mode Field (Timing only) As you can see, transitions are stored in two different ways, depending strictly on chance. Remember that the transition detector only looks at the full 34 bits while the data is stored as two 17 bit samples. So, the transition detector will not see time-tag 3 (101/000) as a transition. However, when it compares it to time-tags 2 (101/101) or 4 (000/000), it sees a difference and detects them as transitions.
The Format Menu Timing Acquisition Mode Field (Timing only) In this case, transitions are being detected with each sample. Therefore, they are all being stored. In addition, each sample pair contains a transition. For example, time tag 1 (100/000) contains a transition and is different from time tag 2 (111/011), which also contains a transition. The difference between the two will trigger the transition detector.
The Format Menu Timing Acquisition Mode Field (Timing only) Increasing Duration of Storage In the 125-MHz mode a transition on any one of the 34 bits each sample (if they are all turned on) will cause storage. Reducing the number of bits that are turned on for any one pod pair will more than likely increase data storage time. Separating data lines which contain fast occurring transitions from lines with slow occurring transitions also helps. When doing this, be sure to cross pod pair boundaries.
The Format Menu Clock Inputs Display Clock Inputs Display Beneath the Clock Inputs display, and next to the activity indicators, is a display of all clock inputs available in the present configuration. Depending on the model, the number of available clocks vary. The J and K clocks appears with pod pair 1/2, the L and M with pod pair 3/4, and clocks N and P with pod pairs 7/8 for the 1660 and 5/6 for the 1661.
The Format Menu Pod Field Pod Field The Pod field identifies which pod of a pod pair the settings of the bit assignment field, pod threshold field, and pod clock fields effect. In the full channel modes, this field is simply an identifier and is not selectable. However, in the half channel mode, the Pod field turns dark which means it is selectable. It is through the Pod field that you select a pod in the pod pair.
The Format Menu Pod Clock Field (State only) Pod Clock Field (State only) The Pod Clock field identifies the type of clock arrangement assigned to each pod. When the Pod Clock field is selected, a clock arrangement type menu appears with the choices of Master, Slave, or Demultiplex. Once a pod clock is assigned a clock arrangement, its identity and function follows what is configured in the Master and Slave Clock fields.
The Format Menu Pod Clock Field (State only) Slave This option specifies that data on a pod designated "Slave Clock" are latched when the status of the slave clock inputs meets the requirements of the slave clocking arrangement. Then, followed by a match of the master clock and the master clock arrangement, the slave data is strobed into analyzer memory along with the master data. See the figure below.
The Format Menu Pod Clock Field (State only) Demultiplex The Demultiplex mode is used to store two different sets of data that occur at different times on the same channels. In Demultiplex mode, only one pod of the pod pair is used, and that pod is selectable. Both the master and slave clocks are used in the Demultiplex mode. Channels assignments are displayed as Demux Master and Demux Slave. For easy recognition of the two sets of data, it is recommended to assign slave and master data to separate labels.
The Format Menu Pod Clock Field (State only) When the analyzer sees a match between the slave clock input and the Slave Clock arrangement, Demux Slave data is latched. Then, followed by a match of the master clock and the master clock arrangement, the slave data is strobed into analyzer memory along with the master data. If multiple slave clocks occur between master clocks, only the data latched by the last slave clock prior to the master clock is strobed into analyzer memory.
The Format Menu Pod Threshold Field Pod Threshold Field The pod threshold field is used to set a voltage level that the data must reach before the analyzer recognizes and displays it as a change in logic levels. You specify a threshold level for each pod in a pod pair. The level specified for each pod is also assigned to the pod’s clock threshold.
The Format Menu Pod Threshold Field User When USER is selected as the threshold level, the data signals must reach a user selectable value. The range of this value is between −6.0 volts to +6.0 volts.
The Format Menu Master and Slave Clock Field (State only) Master and Slave Clock Field (State only) The Master and Slave Clock fields are used to construct a clocking arrangement. A clocking arrangement is the assignment of appropriate clocks, clock edges, and clock qualifier levels which allow the analyzer to synchronize itself on valid data.
The Format Menu Master and Slave Clock Field (State only) Clock edges are ORed to clock edges, clock qualifier are ANDed to clock edges, and clock qualifiers can be either ANDed or ORed together. All clock and qualifier combinations on the left side of the graphic line are ORed to all combinations on the right side of the line.
The Format Menu Setup/Hold Field (State only) Setup/Hold Field (State only) Setup/Hold adjusts the relative position of the clock edge with respect to the time period that data is valid. When the Setup/Hold field is selected, a configuration menu appears. Use this Setup/Hold configuration menu to select each pod in the analyzer and assign a Setup/Hold selection from the selection list. With a single clock edge assigned, the choices range from 3.5-ns Setup/0.0-ns Hold to 0.0-ns Setup/3.5-ns Hold.
The Format Menu Setup/Hold Field (State only) The relationship of the clock signal and valid data under the default setup and hold is shown in the figure below. Default Setup and Hold If the relationship of the clock signal and valid data is such that the data is valid for 1 ns before the clock occurs and 3 ns after the clock occurs, you will want to use the 1.0 setup and 2.5 hold setting.
The Format Menu Symbols Field Symbols Field The Symbols field is located directly below the Run field in the upper right corner of the Format menu. This field is used to access the symbol tables. The symbol tables are used to define a mnemonic for a specific bit pattern of a label. You can specify up to 1000 total symbols, and use them freely between available analyzers. When measurements are made, the mnemonic is displayed where the bit pattern occurs using the selected symbol base.
The Format Menu Symbols Field Symbol Symbol Located in the Data Label Field The Label field identifies the label for which you are specifying symbols. When you select this field, a selection menu appears that lists all the labels turned on for that analyzer. Each label has a separate symbol table, so you can give the same name to symbols defined under different labels. From the label selection menu, select the label for which you wish to specify symbols.
The Format Menu Symbols Field Symbol Width Field The Symbol Width field is used to specify how many characters of the symbol name will be displayed when the symbol is referenced in the Trigger, Waveform, and Listing menus. To change the Symbol Width, simply highlight the field and turn the knob to set the number of characters in the symbol. You can set the logic analyzer to display from 1 to 16 of the characters in the symbol name.
The Format Menu Symbols Field To add, delete, or modify symbols in the symbol table, select a symbol name and use one of the following options from the pop-up selection list: Modify Symbol If you select this option, a cursor appears under the first letter of the symbol name. Make any changes desired, then press the Done key. Add a Symbol When you select this option, a cursor appears in a blank name field. Type in the new name, then press the Done key.
The Format Menu Label and Pod Rolling Fields Label and Pod Rolling Fields The Label and Pod rolling fields allow you to view offscreen labels and pods. To view offscreen labels, select the Labels roll field to place the roll indicator into the field, then rotate the knob. The labels scroll up and down. The Pods rolling field allows you to view offscreen pods. To view offscreen pods, select the Pods roll field to place the roll indicator in the field, then rotate the knob.
The Format Menu Label Assignment Fields Label Assignment Fields The label assignment fields display the user-defined label names. Custom label names are used when there are different types of data which must be tracked. The label column contains 126 label fields that you can define. The analyzer displays only 8 labels at any time. The default label names are Lab1 through Lab126. However, the names can be modified to any six character string by highlighting the field, then typing in the new name.
The Format Menu Label Assignment Fields Turn Label Off The Turn Label Off option turns off the label. When a label is turned off, the label name and the bit assignments are saved by the logic analyzer. This gives you the option of turning the label back on and still having the bit assignments and name if you need them. With labels off, the label names remain displayed for identification and searching purposes. With labels off, memory can be saved if in transitional timing.
The Format Menu Label Polarity Fields Label Polarity Fields The Label Polarity fields are used to assign a polarity to each label. The default polarity for all labels is positive ( + ). You change the label polarity by selecting the polarity field, which toggles the polarity between positive ( + ) and negative ( −). When the polarity is inverted, all data as well as bit pattern specific configurations used for identifying, triggering, or storing data reflect the change of polarity.
The Format Menu Bit Assignment Fields Bit Assignment Fields The bit assignment fields are used to assign physical channels to labels. The convention for bit assignment is as follows: • * (asterisk) indicates an assigned bit. • . (period) indicates an unassigned bit. To change a bit assignment, select the bit assignment field and using the knob, move the cursor to the bit you want to change, then select an asterisk or a period.
The Format Menu Bit Assignment Fields Labels may have from 1 to 32 channels assigned to them. If you try to assign more than 32 channels to a label, the logic analyzer will beep, indicating an error. A message will appear at the top of the screen telling you that 32 channels per label is the maximum. Channels assigned to a label are numbered from right to left by the logic analyzer.

12 The Trigger Menu
The Trigger Menu The trigger menu is used to configure when the analyzer triggers, what the analyzer triggers on, and what is stored in acquisition memory. In addition, within the Acquisition Control function, prestore and poststore requirements are set. The Trigger menu is divided into three areas, each dealing with a different area of general operation.
The Trigger Menu Sequence Levels Area You use the sequence levels area to view the sequence levels currently used in the trigger specification and their timer status. From this area you can also access each individual level for editing. Resource Terms Area You use the resource terms area to assign values to the resource terms. Resource terms take the form of bit patterns, ranges, and edges.
The Trigger Menu Trigger Menu Map 12–4
The Trigger Menu Trigger Menu Map (Continued) 12–5
Trigger Sequence Levels Sequence levels are the definable stages of the total trigger specification. When defined, sequence levels control what the analyzer triggers on, when the analyzer triggers, and where trigger will be located in the total block of acquired data. In addition, you can qualify what data is stored when trigger occurs. By using sequence levels, you create a sequence of instructions for the analyzer to follow.
The Trigger Menu Editing Sequence Levels The higher level editing, such as adding or deleting entire sequence levels, is done using the Modify Trigger field in the main Trigger menu. You can also modify any existing sequence level from the Modify Trigger field. Another way of editing a specific sequence level is to select the sequence level number field. If the number field in offscreen, select the sequence levels roll field turning it light blue, then use the knob to roll the level back onscreen.
The Trigger Menu Modify Trigger Field Modify Trigger Field The Modify Trigger field allows you to modify the statements of any single sequence level as well as other high level actions like global clearing of existing trigger statements, and adding or deleting sequence levels.
The Trigger Menu Modify Trigger Field Delete Sequence Level If there is more than one sequence level assigned, you are asked which level to delete. Add Sequence Level By default you have one sequence level available at powerup. When you add sequence levels, you are given the choice of inserting them before or after a sequence level. Clear Trigger The Clear Trigger field accesses a selection menu used to clear any user-defined values within the trigger specification or within the resource terms list.
The Trigger Menu Modify Trigger Field Break Down Macros / Restore Macros When a pre-defined macro is broken down, the contents of that macro are displayed in the same long form used in the User-level macro. If the macro uses multiple internal levels, all levels are separated out and displayed in the sequence level area of the Trigger menu. Once the macros in your trigger specification are broken down, the Break Down Macros field changes to Restore Macros.
Pre-defined Trigger Macros Both the state and timing acquisition modes have a macro library containing pre-defined trigger macros. Depending on which acquisition mode you are using, you get the corresponding library. Each macro will require at least one sequence level, and in some cases, may require multiple levels. Sequence levels containing pre-defined macros flow linear without branching. However, if branching is required, the User-level macro can be inserted to provide a branch.
The Trigger Menu Modify Trigger Field State Trigger Macro Library: • • • • • User Mode (User-level macro) Basic Macros Sequence Dependent Macros Time Violation Macros Delay Macros State Trigger Macro Library 12–12
The Trigger Menu Using Macros to Create a Trigger Specification Using Macros to Create a Trigger Specification To configure a trigger specification using trigger macros, follow the procedure below. 1 From the Trigger menu, enter the desired sequence level through the Modify Trigger field, or by selecting a sequence level number. See Also "Editing Sequence Levels" and "Modify Trigger Field" found earlier in this chapter for information on accessing levels.
The Trigger Menu Timing Trigger Macro Library Timing Trigger Macro Library User Mode Basic Macros The following list contains all the macros in the Timing Trigger Macro Library. They are listed in the same order as they appear onscreen. User level - custom combinations, branching The User level is a user-definable level. This level offers low level configuration and uses one internal sequence level. If the "<" duration is used, four levels are required. 1.
The Trigger Menu Timing Trigger Macro Library Pattern/Edge Combinations 1. Find edge within a valid pattern. This macro becomes true when a selected edge type is seen within the time window defined by a designated pattern. It uses two internal sequence level. 2. Find pattern occurring too soon after edge This macro becomes true when a designated pattern is seen occurring within a set duration after a selected edge type is seen. It uses three internal sequence levels. 3.
The Trigger Menu State Trigger Macro Library State Trigger Macro Library User Mode Basic Macros The following list contains all the macros in the State Trigger Macro Library. They are listed in the same order as they appear onscreen. User level - custom combinations, loops The User level is a user-definable level. This level offers low level configuration and uses one internal sequence level. 1. Find anystate "n" times This macro becomes true when the first state it sees occurs "n" number of times.
The Trigger Menu State Trigger Macro Library Sequence Dependent macros 1. Find event 2 "n" times after event 1, before event 3 occurs This macro becomes true when it first finds a designated pattern 1, followed by a selected number of occurrences of a designated pattern 2. In addition, if a designated pattern 3 is seen anytime while the sequence is not yet true, the sequence starts over. If patt2’s "nth" occurrence is coincident with patt3, the sequence starts over. It uses two internal sequence levels.
The Trigger Menu State Trigger Macro Library Time Violations 1. Find event 2 occurring too soon after event 1 This macro becomes true when a designated pattern 1 is seen, followed by a designated pattern 2, and with less than a selected time period occurring between the two patterns. It uses two internal sequence levels.. 2.
The Trigger Menu Modifying the User-level Macro Modifying the User-level Macro Before you begin building a trigger specification using the User-level macro, it should be noted that in most cases one of the pre-defined trigger macros will work. If you need to accommodate a specific trigger condition, or you prefer to construct a trigger specification from scratch, you will use the User-level macro to build from.
The Trigger Menu Modifying the User-level Macro The number of User-level macros you will use, or what you assign to the resource terms is difficult to predict because of the variety of applications. A general approach is to think of each field assignment or each new sequence level as an opportunity to lead the analyzer through key points in the data stream. Your end result is to select the desired point in the data to trigger on, and to store only the data you want.
The Trigger Menu Modifying the User-level Macro Example The following statement looks for the positive, negative, or either going edge type you assigned to term "Edge1" to occur "1" time, before it Triggers . Example The following statement looks for the combination of either a bit pattern you assigned to "a" or an edge type you assigned to "Edge1" to occur "1" time before it Triggers.
The Trigger Menu Modifying the User-level Macro Using Storage Qualification Store qualification enables you to store all data, no data, or just selected data, before trigger occurs. Example The following statement determines that all occurrences of the bit pattern you assigned to "a" will be stored before trigger occurs.
The Trigger Menu Modifying the User-level Macro Using the Occurrence Counters Occurs Field When "Occurs" is selected, the < and > duration functions change to an occurrence counter. Use the occurrence counter to delay sequence evaluation until the resource term has occurred a designated number times. If the "else on" branch becomes true before all specified occurrences of the primary "Trigger on" branch, the secondary "else on" branch is taken.
The Trigger Menu Modifying the User-level Macro Using the Timer Timers are like other resource terms in that they are either true or false. Timers can be set to Start, Stop, Pause, or Continue as the analyzer enters a sequence level. The two timers are global, so each sequence level has the ability to control the same timer. The default timer condition in all sequence levels is Off. Example The following statement assigns the "Timer 1" to the secondary "else on" branch.
The Trigger Menu Modifying the User-level Macro Branching If either the < or > durations is used, only the primary "Trigger on" branch is available, otherwise each sequence level has two way branching. If the primary branch is taken, the analyzer triggers and goes to the next level. If the primary branch is not found, the analyzer immediately evaluates the "Else on" secondary branching term. If the "Else on" term is found, the secondary branch taken is to the designated sequence level.
Resource Terms Resource terms are user-defined variables that are assigned to sequence levels. They are placed into the sequence statement where their bit pattern or edge type is searched for within the data stream. When a match is found, a branch is initiated and the next statement or sequence level is acted upon.
The Trigger Menu Modifying the User-level Macro Edge Terms 1 and 2 (Timing only) The two edge terms are only available in the timing analyzer. Edge terms are assigned either a positive going , negative going, or both edge type. Two global Timers In addition to the resource terms available, there are two global timers available. Each timer can be started, paused, continued, or stopped, from any sequence level. All resource terms and timer terms are listed under a scrollable Terms field.
The Trigger Menu Assigning Resource Term Names and Values Assigning Resource Term Names and Values The Terms field identifies the list of available resource terms within the analyzer. The resource term names (a − j, Edge1, Edge2, Range1, Range2) are default names that can be changed if desired. You assign values in the following two ways: • Using Preset Values • Bit by Bit Assignment Using Preset Values When any of the individual term fields are selected, a configuration pop-up appears.
The Trigger Menu Assigning Resource Term Names and Values Clear (=X) Sets the Term Assignment fields as follows: In Terms a − j, the assignment field is set to all Xs (don’t cares). In Range 1, 2 terms, the two assignment fields are set to maximum (Fs) and minimum (0s) settings. In Timers 1, 2 terms, the assignment field is reset to a minimum time of 400 ns. In Edge 1, 2 terms, the assignment field is reset to a period (.).
The Trigger Menu Assigning Resource Term Names and Values Edge Terms If you want to qualify an edge, place the appropriate edge on the data channel you are watching. When the analyzer sees the correct edge, the term becomes true. Edge terms can be used singularly or in combination with each other across all assigned channels. When you specify an edge on more than one channel, the analyzer ORs the edges. Terms Edge1 $* Edge2 XX .
The Trigger Menu Assigning Resource Term Names and Values Timer Terms Each Timer term is assigned to either of the two analyzers, but not both. With timers inserted into sequence levels, you can start a timer in one level, pause it, or stop it in another sequence level. Timers are either true or false. Timers start as you enter the sequence level, and when its count expires, it becomes true. If a timer is paused in one level, it must be continued in another level before it can count through.
The Trigger Menu Label and Base Fields Label and Base Fields The Label and Base fields show up together in all menus except the Format menu. When a new label is assigned, a base field is automatically assigned to that label. Label Field Labels are displayed throughout the analyzer as they were assigned in the Format menu.
The Trigger Menu Arming Control Field Arming Control Field The Arming Control field shown below accesses an Arming Control menu. The Arming Control menu is used to configure the arm signals between analyzers, and the Port In/Out signals. By using the arming signals, you influence the order in which the analyzers triggers in a cross-domain measurement.
The Trigger Menu Arming Control Field Arming Control Between Analyzers If both analyzers in a module are turned on, you can configure one analyzer to arm the other. An example of this is when a state analyzer triggers on a bit pattern, then arms a timing analyzer which captures and displays the waveform after it triggers. When you select the analyzer name field in the Arming Control menu shown below, a pop-up menu appears which you use to select where the Arm In signal is coming from.
The Trigger Menu Arming Control Field Arming Control Using External BNCs A more complex arming example involves passing arm signals in and out through the External BNCs on the rear panel. The first analyzer is armed by an Arm In signal from an external trigger source or another test/measurement entity. After the first analyzer triggers, it arms the second analyzer.
Acquisition Control The Acquisition Control menu is used to set the acquisition mode, the trigger position within available memory, and the sample period. Acquisition Mode Field The Acquisition Mode field toggles between Manual and Automatic. When set to Automatic, the position of stored data relative to trigger and the sample rate are based on the sec/Div and delay settings in the Waveform menu.
The Trigger Menu Trigger Position Field Trigger Position Field The Trigger Position field accesses a selection menu with the options of Start, Center, End, User Defined, or Delay. When an option is selected, that point of the available memory is positioned relative to the trigger. A representation of this is shown by the blue graphic bar with the "Trig" indicator line. The Trigger Position field determines how much data is stored before and after the trigger occurs for all subsequent acquisitions.
The Trigger Menu Sample Period Field End When the trigger position is set to End, the end point of available memory is positioned relative to the trigger point. This results in maximum pretrigger data and minimum posttrigger data. User Defined When the trigger position is set to User Defined, a Post Store field appears. Use this field to set the trigger position any where between 0% and 99%. As the Post Store is adjusted, the blue graphic bar indicates the trigger position.
The Trigger Menu Count Field (State only) Count Field (State only) The Count field is used to access a selection menu which is used to stamp the acquisition data at each memory location with either a Time tag or a State count tag. Storing Time or State tags If you have all pod pairs assigned, the state acquisition memory is reduced by half, when time or state tags are turned on. You can maintain full memory depth if you leave a specified pod pair unassigned.
The Trigger Menu Count Field (State only) Time Time count places time tags on all displayed pretrigger and posttrigger data. Data stored before trigger has negative time numbers and data stored after trigger has positive time numbers. Time tag numbering is set to be either relative to the previous memory location or absolute from the trigger point. Selecting the Absolute or Relative option is done by toggling the Absolute/Relative field. Time tag resolution is 8 ns.
13 The Listing Menu
The Listing Menu The Listing menu is a display menu for state and timing analyzer measurements. The listing is a display of data, address, and control status in memory at each clock cycle in a microprocessor-based system. The acquired data is displayed in the order the analyzer placed the data into analyzer memory. Data is grouped and displayed by label and in a selectable numeric base. Labeled data from the other state analyzer can be interleaved into the same display.

The Listing Menu Markers Field Markers Field The Markers field is used to access the markers selection menu. When the Markers field is selected, a marker selection menu appears with the marker choices available with the present analyzer configuration. State Analyzer Types In a state analyzer with count Time and count State turned off in the Trigger menu, only Pattern markers are available. With count Time turned on, additional choices of Time markers and Statistics markers become available.
Pattern Markers When Pattern markers are selected, two markers labeled X and O become available. Pattern markers identify and mark unique bit patterns in the data listing. Once the unique bit patterns are marked, they can be used as reference points or as criteria for a stop measurement. The markers are graphically displayed by horizontal lines. In addition, both markers are labeled at the left end of the marker line.
The Listing Menu Find X-pattern / O-pattern Field Find X-pattern / O-pattern Field The Find X-pattern/O-pattern field is a toggle field. When you toggle the Find X-pattern/O-pattern fields, the functionality of the occurrence and trace start fields switch to the other marker. In addition, when the Find X-pattern/O-pattern field is toggled, the data listing will shift so the data marked will appear at center screen.
The Listing Menu Pattern Occurrence Fields Pattern Occurrence Fields The X-pattern and O-pattern occurrence fields designate which pattern occurrence the marker is placed on. The occurrence field is set by highlighting the field, then turning the knob or entering a number from the front-panel keypad. The reference point from which the occurrence counter starts is either the trigger point, the start of the trace, or in the case of the O-marker, the X-marker.
The Listing Menu From Trigger / Start / X Marker Field From Trigger / Start / X Marker Field The from Trigger/Start/X marker field is used to access the selection pop-up for the start point of the X and O marker occurrence counters. The start points available for the X-marker are either the trace start point or the trigger point. The start points available for the O-marker are the trace start point, trigger point, or the X-marker.
The Listing Menu Specify Patterns Field Specify Patterns Field The Specify Patterns field only appears when the markers are set to Pattern. When the Specify Patterns field is selected, a pop-up menu appears that is used to assign the bit patterns for the X and O markers, the X and O entering/leaving markers, and the stop measurement criteria.
The Listing Menu Specify Patterns Field X and O entering / leaving Fields (Timing only) If the analyzer is configured as Timing, the X and O pattern markers are placed at either the beginning of the pattern occurrence (entering) or at the end of the pattern occurrence (leaving). When the entering/leaving field of either X or O markers is selected, it toggles between the two choices. Whichever choice you toggle the field to, the pattern you place in the pattern display field will apply to that choice.
The Listing Menu Specify Patterns Field Pattern Display Fields The pattern display field displays the alphanumeric bit pattern specified for each X and O marker in all designated labels. The bit pattern is displayed in the same numeric base and same order as the data listing. When the pattern display field is highlighted, a bit pattern can be entered using the front-panel keypad.
The Listing Menu Specify Patterns Field Label and Base Fields The Label and Base fields show up together in all menus except the Format and Configuration menus. When a new label is assigned, a base field is automatically assigned to that label. Label Field Labels in the Specify Patterns menu are the same labels assigned in the Format menu. These labels will be displayed throughout the analyzer as they were assigned in the Format menu.
The Listing Menu Stop Measurement Field Stop Measurement Field The stop measurement function allows you to specify a condition which stops the analyzer measurement during a repetitive run. If two analyzers are configured, both analyzers stop when either specified stop condition is satisfied. When the Stop measurement field is selected, a stop measurement type menu appears. Depending on the analyzer configuration, you have the choices of Off, X-O, and Compare.
The Listing Menu Stop Measurement Field X-O The X-O option is available in the Timing analyzer and in the State analyzer with its count set to Time. When X-O is selected, a repetitive run is stopped when a comparison of the time period between the X and O markers and one of the following time period options is true: Less Than X-O time must be less than the time value that you specify in the Time field. Greater Than X-O time must be greater than the time value that you specify in the Time field.
The Listing Menu Stop Measurement Field Compare When you select Compare, a repetitive run is stopped when a comparison of data in the Listing menu and data and criteria in the Reference listing of the Compare menu matches an equality selection. The equality selection is set from the Equal/Not Equal selection pop-up menu. Equal The data and compare criteria in the Compare menu must be equal to the data in the Listing menu.
The Listing Menu Clear Pattern Field Clear Pattern Field The Clear Pattern field is used to reset the X and O Marker pattern display fields back to default (don’t care = X). The Clear Pattern field accesses a selection menu with the choices of All (displays X & ) patterns for 1664A), X-pattern, or O-pattern.
Time Markers Time markers are indicators located in the data listing that are used as reference marks to obtain time values between each marker, or between each marker and the trigger point. In a State analyzer, Time markers only become available when the Count field in the Trigger menu is set to Time. The markers are graphically displayed by horizontal lines. In addition, both markers are labeled at the left end of the marker line.
The Listing Menu Trig to X / Trig to O Fields Trig to X / Trig to O Fields The Trig to X and Trig to O fields are both display fields as well as configuration fields. The Trig to X and Trig to O fields display the time between the trigger point and the markers. Marker position is set by selecting the desired field and entering a value using the front-panel keypad. The units are set by turning the knob when the assignment pop-up is open.
Statistics Markers After patterns are assigned to the X and O markers, statistical information is available when markers are set to Statistics. The logic analyzer displays the following information: • Number of valid runs (runs where Pattern markers were able to be placed on specified patterns). • Minimum time between the X and O Pattern markers. • Maximum time between the X and O Pattern markers. • Average time between the X and O Pattern markers.
The Listing Menu Trig to X / Trig to O Fields Statistics are based on the time between the X and O. Both markers must be found before valid statistical information is displayed. In repetitive run mode, the display is updated each time a valid run occurs until you select Stop. If you select Run after Stop, the statistics continue to update without loss of information. In single run mode, each time you select Run an additional valid run will be added to the data and the statistics will be updated.
States Markers (State only) States markers are indicators located in the data listing that are used as reference marks to obtain the number of states between each marker, or between each marker and the trigger point. States markers are only available in a state analyzer with the Count field set to State in the Trigger menus. The markers are graphically displayed by horizontal lines. In addition, both markers are labeled at the left end of the marker line.
The Listing Menu Trig to X / Trig to O Fields Trig to X / Trig to O Fields The Trig to X and Trig to O fields are both display fields as well as configuration fields. The Trig to X and Trig to O fields display the number of states between the trigger point and the marker. Marker position is set by selecting the desired field and entering a value using the front-panel keypad. Marker position can also be set by simply turning the knob when the roll indicator is present.
The Listing Menu Data Roll Field Data Roll Field The column of numbers at the far left represents the location of the acquired data in the state analyzer’s memory. The numbered positions are also known as the state locations and are relative to the trigger state location. The column of state locations along with its data can be rolled to display offscreen data by using the data roll field. The data roll field is the small rectangular box located in the middle of the state location column.
The Listing Menu Label and Base Fields Label and Base Fields The Label and Base fields show up together in all menus except the Format and Configuration menus. When a new label is assigned, a base field is automatically assigned to that label. Label Field Labels in the Listing menu are the same labels assigned in the Format menu. These labels will be displayed throughout the analyzer as they were assigned in the Format menu.

14 The Waveform Menu
The Waveform Menu The Waveform menu is one of the analyzer display menus. You use the Waveform menu to view either state or timing data in a format similar to an oscilloscope display. Data is displayed with the horizontal axis representing either states or time, and the vertical axis representing logic highs and lows. The type of data displayed depends on whether the Type field in the Configuration menu is set to State or Timing.

The Waveform Menu Acquisition Control Field Acquisition Control Field The function of the Acquisition Control field in the Waveform menu is the same as in the Trigger menu. Refer to the "Acquisition Control Field" in the Trigger menu for complete details.
The Waveform Menu Accumulate Field Accumulate Field The Accumulate field controls whether old data is cleared or displayed along with new data. The Accumulate field will toggle On/Off. When Accumulate is on, the analyzer displays the data from a current acquisition on top of the previously acquired data. When Accumulate is off, the display is cleared before each new run cycle.
The Waveform Menu States Per Division Field (State only) States Per Division Field (State only) When the analyzer Type field in the Configuration menu is set to State, the analyzer uses external clocks from the system under test. In this mode, the X-axis of the waveform display is measured in states per division. You use the states/Div field to select the states per division resolution of the X-axis.
The Waveform Menu Seconds Per Division Field (Timing only) Seconds Per Division Field (Timing only) When the analyzer Type field in the Configuration menu is set to Timing, the analyzer uses its own internal clock. In this mode, the X-axis of the waveform display is measured in seconds per division. You use the sec/Div field to select the seconds per division resolution of the X-axis. The range of the sec/Div field is 1 ns/Div to 1.0 ks/Div.
The Waveform Menu Delay Field Delay Field Depending on the analyzer configuration, a positive or negative delay measured in either states or time can be set. The Delay field allows you to scroll the data and place the display window at center screen. Changing the delay will not effect the data acquisition unless it is a timing analyzer and the acquisition mode is automatic. The delay range of a timing analyzer is from −2500 seconds to +2500 seconds.
The Waveform Menu Sample Period Display (Timing only) Sample Period Display (Timing only) The sample period display only appears in a timing analyzer. A sample period is the interval of time between new data samples. Every time a new measurement is taken, the analyzer updates the display. The Current Sample period display is the sample period used for the last acquisition. The Next Sample period is the new sample period to be used at the next acquisition.
The Waveform Menu Sample Period Display (Timing only) Timing waveforms are reconstructed relevant to the sample period. The shorter sample period puts more sample points on the waveform for a more accurate reconstruction but also fills memory more quickly. If the sec/Div is changed resulting in a change in the next sample period, you must run the analyzer again before the current sample period display is updated.
The Waveform Menu Markers Field Markers Field The Markers field is used to access the markers selection menu. When the Markers field is selected, a marker selection menu appears with the marker choices available under the present analyzer configuration. State Analyzer Types In a state analyzer with count turned off in the Trigger menu, only Pattern markers are available. With count Time turned on, additional choices of Time markers and Statistics markers become available.
Pattern Markers When Pattern markers are selected, two markers labeled X and O become available. Pattern markers identify and mark unique bit patterns in the waveform display. Once the unique bit patterns are marked, they can be used as reference points or as criteria for a stop measurement. The markers are graphically accented in the display by dashed lines. In addition, both markers are labeled at the bottom of the display in the Display Location Reference Line.
The Waveform Menu X-pat / O-pat Occurrence Fields X-pat / O-pat Occurrence Fields The X-pat/O-pat occurrence fields designate which pattern occurrence the marker is placed on. The occurrence field is set by first highlighting the field, then turning the knob or entering a number from the front-panel keypad. The reference point from which the occurrence counter starts is the trigger point, the start of the trace, or, in the case of the O-marker, the X-marker.
The Waveform Menu From Trigger / Start / X Marker Field From Trigger / Start / X Marker Field The from Trigger/Start/X marker field is used to access the selection pop-up for the start point of the X and O marker occurrence counters. The start points available for the X-marker are either the trace start point or the trigger point. The start points available for the O-marker are either the trace start point, trigger point, or the X-marker.
The Waveform Menu X to O Display Field (Timing only) X to O Display Field (Timing only) The X to O display field only appears when the analyzer is configured as Timing. The X to O display field shows the time between the X and O markers.
The Waveform Menu Center Screen Field Center Screen Field The Center Screen field accessed a menu which allows you to position the marked points of the waveform display relative to the center of the waveform display. About Trigger The About Trigger selection is the default position. This choice will position the point of the waveform where the trigger occurred, at center screen.
The Waveform Menu Specify Patterns Field Specify Patterns Field The Specify Patterns field only appears when the markers are set to Pattern. When the Specify Patterns field is selected, a pop-up menu appears that is used to assign the bit patterns for the X and O markers, the X and O entering/leaving, and the stop measurement criteria.

The Mixed Display Menu (1660A Through 1663A Only) The Mixed Display menu is a multidisplay menu which consists of a state listing display located at the top of the menu and a waveform display located at the bottom of the menu. The Mixed Display menu is used to view both state and timing data in the same display. The Mixed Display menu only becomes available when at least one analyzer is configured as a state analyzer, with its Count field in the Trigger menu set to Time.
The Mixed Display Menu Inserting Waveforms Inserting Waveforms To insert waveforms use the same procedure for selecting waveforms when in the Waveform menu. See Also "Waveform Display" in the Waveform menu chapter for information on the field definitions and the waveform selection functions. Interleaving State Listings Interleaved state listings allows you to view two labels and their data from different analyzers in the same column.
The Mixed Display Menu Time-Correlated Displays Time-Correlated Displays Once the Time markers are set in the Waveform display area of the Mixed Display menu, time-correlated X and O Time markers will be displayed in both the listing and the waveform display areas. The analyzer uses a counter to track time between the triggering of one display and the triggering of the other display. It uses this count to reconstruct time-correlated data.
The Mixed Display Menu Markers Markers The markers in the Mixed Display menu are not the same as in the individual Listing and Waveform menus. You must place new Time markers on your points of interest in the Mixed Display. Even though you have placed markers in the individual listing and waveform displays, the markers will not transfer to the Mixed Display menu. Time Markers Only Time markers are available in the Mixed Display menu. You set the Time markers in the waveform display area of the menu.

16 The Chart Menu
The Chart Menu State Chart is a software post-processing feature that provides the ability to build x-y charts of label activity using state data. The Chart menu builds a graphical representation of the system under test. The y-axis always represents data values for a specified label. You can select whether the x-axis represents states (ie. rows in the state listing) or the data values for another label.
The Chart Menu Label Value vs. Label Value Charts When labels are assigned to both axis, the chart shows how the data acquired under one label varies in relation to the other for a particular measurement. Label values are always plotted in ascending order from the bottom to the top of the chart and in ascending order from left to right across the chart. Plotting a label against itself will result in a diagonal line from the lower left to upper right corner.
