1 Getting Started What Is In This Chapter This chapter contains information on how to use the Agilent 8360 L-Series Swept CW Generator. The information is separated into three sections. Basic For the novice user unfamiliar with the 8360 L-Series Swept CW Generator. This section describes the basic features of the swept CW generator. Advanced For the user familiar with swept CW generators, but not necessarily familiar with how to use the special features of the 8360 L-Series Swept CW Generator.
How To Use This Chapter Equipment Used In Examples To use this chapter e ectively, refer to the tabbed section \Menu Maps". Menu maps can be folded out to be viewed at the same time as the Getting Started information, as illustrated. The following table lists the equipment used in the operation examples shown in this chapter. You can substitute equipment, but be aware that you may get di erent results than those shown.
Getting Started Basic Introducing the Agilent 8360 The 8360 L-Series Swept CW Generators are high performance, broadband frequency swept CW generators. L-Series Swept CW Generators Figure 1-1. The 8360 L-Series Swept CW Generator initializes the front panel settings and runs the swept CW generator through a brief self-test. In the following examples, unless 5.
Display Area Figure 1-2. Display This area typically displays the frequency and power information of the current instrument state. When data entry is expected, the swept CW generator uses all or part of this area to record the entries. The active entry arrow (-->) indicates the active entry function and its current value. Message Line: This line is used to display: ALC level status. Unlock information. Timebase status. RF output status.
Entry Area All function values are changed via the rotary knob and/or keys of the entry area. Figure 1-3. Entry Area The following are active only when the swept CW generator expects an input. 4 5: This key lets you turn o or on the active entry area. Turning o the entry area after a value is entered prevents accidental changes. ENTRY ON LED: This LED lights when the entry area is active. Arrow Keys: The up/down arrow keys let you increase or decrease a numeric value.
CW Operation and Start/Stop Frequency Sweep CW Operation CW operation is one of the major functions of the swept CW generator, and is easy to do using front panel keys. In CW operation, the swept CW generator produces a single, low-noise, synthesized frequency. Try this example: Press 4 5 4 5 4 5 4 5 4 5 4 5 4 5 4 5 4 5 4 5 4 5. Check the active entry area. It indicates: CW 1 2 . 3 4 5 6 7 8 GHz --> CW: 12345.

Center Frequency/Span Operation Center frequency/span is another way of establishing swept operation. This is just a di erent way of de ning sweep limits. As an example of center frequency/span operation: Press 4 5 45 4 5. Press 4 5 4 5 4 5. The swept CW generator is now sweeping from 3.5 to 4.5 GHz (to view these gures, press either 4 5 or 4 5, then 4 5). The data display area indicates the center frequency, as well as, the span. Notice that the green SWEEP LED is on.

Continuous, Single, and Manual Sweep Operation Continuous sweep is the operation mode set when the swept CW generator is preset. It simply means that when the swept CW generator is performing a swept operation, the sweeps will continuously sweep-retrace-sweep-retrace until a di erent sweep mode is selected. To choose this sweep mode, press 4 5. To change from continuous sweep to single sweep operation, press 4 5.
Figure 1-7. Continuous, Single, and Manual Sweep Operation Single Sweep Continuous Sweep Manual Sweep 1. Press 4SINGLE5. 1. Press 4CONT5. 1. Press SWEEP 4MENU5. 2. Press Manual Sweep . 3. Use the rotary knob to adjust frequency.
Marker Operation The swept CW generator has ve frequency markers that can be used as xed frequency \landmarks," or as variable frequency pointers on a CRT display. To view the marker features of the swept CW generator on a CRT, connect the swept CW generator as shown in Figure 1-8. Refer to menu map 3, MARKER. Press 4 5. Press 4 5 4 5 4 5. Press 4 5 4 5 4 5. Press 4 5. Select Marker M1 and enter 4 5 4 5. The swept CW generator is sweeping from 3 to 7 GHz, with a 100 ms sweep speed.
Marker 1 was chosen because it is selected as the delta marker reference. To change reference markers, select Delta Mkr Ref . Select M2 as the reference. Watch the display change to indicate: NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN NNNNNNNN --> DELTA MKR (3-2) : 1200.
Saving and Recalling an Instrument State The save/recall registers store and access a previously set instrument state. For example, set the swept CW generator to sweep from 3 to 15 GHz at a 010 dB power level, with markers 1 and 2 set at 4.5 and 11.2 GHz. Press 4 5 4 5 4 5. Press 4 5 4 5 4 5 4 5. 5 405 4 5 4 5 4 5. Press 4 Press 4 5. Select Marker M1 4 5 4 5 4 5 4 5. Select Marker M2 4 5 4 5 4 5 4 5 4 5. To save this instrument state in register 1, press 4 5 4 5.
Figure 1-9. Saving and Recalling an Instrument State Save Recall 1. Set up swept CW generator as desired. 2. Press 4SAVE5. 3. Press a number 1 through 8. 1. Press 4RECALL5. 2. Press a number 0 through 8.
Power Sweep and Power Slope Operation Power Sweep Operation The power sweep function allows the power output to be swept (positive or negative) when the swept CW generator is in the CW frequency mode. The power output of the swept CW generator determines the maximum leveled power sweep that can be accomplished. For this example, refer to the \Menu Map" section. Zero and calibrate the power meter. Connect the instruments as shown in Figure 1-10. Press 4 5 4 5 4 5. 5 45 4 5. Press 4 Press 4 5 45 4 5 4 5.
Select Power Sweep (asterisk on). Press 4 5. The swept CW generator performs a power sweep beginning at 020 dBm and ending at +5 dBm. The power meter indicates +25 dB. NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN SINGLE Power Slope Operation This function allows for compensation of high frequency system or cable losses by linearly increasing the power output as the frequency increases. For this example, refer to the \Menu Map" section. Press Power Slope , the active entry area displays: --> RF SLOPE: X.
Advanced Getting Started Advanced This section of Chapter 1 describes the use of many of the unique features of the 8360 L-Series Swept CW Generators. The format used is similar to the one used on the previous pages. When referred to a menu map number, go to the Menu Map tab and unfold the menu map so that you can view it together with the text. Some menus have more than one page of softkeys. Select the more m/n softkey to view the next page of softkeys.
Advanced Table 1-1.
Externally Leveling the Swept CW Generator Leveling with Detectors/Couplers /Splitters In externally leveled operations, the output power from the swept CW generator is detected by an external sensor. The output of this detector is returned to the leveling circuitry, and the output power is automatically adjusted to keep power constant at the point of detection. Figure 1-11 illustrates a typical setup for external leveling.
To level externally: 1. Set up the equipment as shown. For this example, the detector/coupler setup is used. 2. Refer to menu map 1. 3. Press 4 5. 4. Select Leveling Point ExtDet . 5. Set the coupling factor. Select Coupling Factor 405 4 5 4 5 4 5. Power splitters have a coupling factor of 0 dB.
Figure 1-12.
External Leveling Used With the Optional Step Attenuator Some external leveling applications require low output power from the swept CW generator. The swept CW generator automatically uncouples the attenuator from the ALC system for all external leveling points. Press 4 5. Note the display. It shows: POWER LEVEL --> ATTEN 0 dB, POWER LEVEL: 0.
Leveling with Power Meters Leveling with a power meter is similar to leveling with a diode detector. Figure 1-13 shows the setup for power meter leveling. Figure 1-13. Leveling with a Power Meter 1. 2. 3. 4. 5. Set up the equipment as shown. Be sure to set the power meter to manual range mode and note the range. Refer to menu map 1. Press 4 5. Select Leveling Point PwrMtr . Select Pwr Mtr Range . Enter the range value set for the power meter as noted in step 1. 6. Select Coupling Factor , press 4 5 4 5.
Leveling with MM-wave Source Modules Millimeter-wave source module leveling is similar to power meter leveling. The following gures illustrate the setups for leveling with a mm-wave source module. Figure 1-14. MM-wave Source Module Leveling High power model swept CW generators can externally level mm-wave source modules to maximum speci ed power without a microwave ampli er.
Figure 1-15. MM-wave Source Module Leveling Using a Microwave Amplifier 1. 2. 3. 4. 5. Hint Set up the equipment as shown. Refer to menu map 1. Select Leveling Point Module . Select Module Menu . Select Module Select Auto or Front or Rear , depending on where the interface connection is made. All of the ALC data necessary to communicate properly with the swept CW generator is exchanged via the SOURCE MODULE INTERFACE.
Working with Mixers/Reverse Power Effects Note Uncoupled operation applies to Option 001 swept CW generators only. Uncoupled operation is useful when working with mixers. Figure 1-16 shows a hypothetical setup where the swept CW generator is providing a small signal to a mixer. The swept CW generator output is 08 dBm, which in Leveling Mode Normal results in ATTEN = 0 dB, ALC Level = 08 dBm. The mixer is driven with an LO of +10 dBm, and has LO to RF isolation of 15 dB.
Figure 1-16. Reverse Power Effects, Coupled Operation with 08dBm Output Figure 1-17.
Working with Spectrum Analyzers/Reverse Power Effects Reverse power is a problem with spectrum analyzers that do not have preselection capability. Some analyzers have as much as +5 dBm LO feedthrough coming out of their RF input, at some frequencies. The e ects of reverse power are less in the heterodyne band (0.01 to 2.0 GHz) where the power ampli er provides some broadband matching. Similarly, at frequencies above 2.
Optimizing Swept CW Generator Performance Creating and Applying the User Flatness Correction Array The following examples demonstrate the user atness correction feature: 1. Using an HP/Agilent 437B power meter to automatically enter correction data for a swept 4 to 10 GHz measurement. 2. Manually entering correction data for a stepped (List Mode) measurement. 3. Making swept mm-wave measurements, automatically entering correction data for an arbitrary list of correction frequencies. 4.
Creating a User Flatness Array Automatically, Example 1 In this example, a atness array containing correction frequencies from 4 to 10 GHz at 1 GHz intervals is created. An HP/Agilent 437B power meter controlled by the swept CW generator through the interface bus is used to enter the correction data into the atness array. For this example, refer to menu map 5, POWER. 1.
Note No other devices can be connected to the GPIB cable. Set up Swept CW Generator Parameters 6. On the swept CW generator, press 4 7. FREQUENCY 4 5 4 5 4 5, 4 5 45 4 5. 8. 4 . PRESET5 START POWER LEVEL 0 4 STOP5 GHz . 415 405 4GHz5 dB(m) Access User Flatness Correction Menu 9. Press POWER 4 5. Select Fltness Menu . 10. Select Delete Menu Delete All . This step insures that the atness array is empty. 11. Press 4 5. Leave the delete menu and return to the previous softkey menu. 12.
Creating a User Flatness Array, Example 2 This example shows how to use the swept CW generator and a power meter in manual entry mode. This example also introduces two features of the swept CW generator. The softkey Freq Follow simpli es the data entry process and the softkey List Mode sets up a list of arbitrary test frequencies. The frequency follow feature automatically sets the source to a CW test frequency equivalent to the active correction frequency in the user atness correction table.
Figure 1-19. Creating a User Flatness Array For this example, refer to menu map 5, POWER. 1. The equipment setup shown in Figure 1-19 assumes that if your setup has an external leveling con guration, the steps necessary to correctly level have been followed. If you have questions about external leveling, refer to \Externally Leveling the Swept CW Generator". Set up Power Meter 2. Zero and calibrate the power meter/sensor. 3. Connect the power sensor to the point where atness corrected power is desired.
Access User Flatness Correction Menu 9. Press POWER 4 5. Select Fltness Menu . 10. Select Delete Menu Delete All . This step insures that the atness array is empty. 11. Press 4 5. Leave the delete menu and return to the previous softkey menu. 12. Select Copy List This step copies the frequency list into the correction table in sequential order. 13. Select Freq Follow . This sets the swept CW generator to CW frequency mode to facilitate taking correction information.
Swept mm-wave Measurement with Arbitrary Correction Frequencies, Example 3 Note The focus of this example is to use user atness correction to obtain at power at the output of the HP/Agilent 83550 series mm-wave source modules. In this case we will use non-sequential correction frequencies in a swept 26.5 to 40 GHz measurement with an HP/Agilent 83554 source module.
Figure 1-20. Creating Arbitrarily Spaced Frequency-Correction Pairs in a Swept mm-wave Environment For this example, refer to menu map 5, POWER. 1. The equipment setup shown in Figure 1-20 assumes that you have followed the steps necessary to correctly level the con guration. If you have questions about external leveling, refer to \Externally Leveling the Swept CW Generator". Set up Power Meter 2. Zero and calibrate the power meter/sensor. 3. Connect the power sensor to test port. 4.
Note U, V, and W-band power sensors are not available from Agilent. For these frequencies use the Anritsu ML83A Power Meter with the MP715-004 (40 to 60 GHz), the MP716A (50 to 75 GHz), or the MP81B (75 to 110 GHz) power sensors. Since the Anritsu model ML83A Power Meter is not capable of internally storing power sensor cal factors, you must manually correct the data entry. Refer to example 2 for information on manual entry of correction data. Set up Swept CW Generator Parameters 5. 5.

Scalar Analysis Measurement with User Flatness Corrections, Example 4 Note The following example demonstrates how to set up a scalar analysis measurement (using an HP/Agilent 8757 Scalar Network Analyzer) of a 2 to 20 GHz test device such as, an ampli er. User atness correction is used to compensate for power variations at the test port of a directional bridge. Follow the instructions to set up the swept CW generator, then con gure the system as shown in Figure 1-21.
Example Overview Note In this example, you use an HP/Agilent 437B power meter to automatically enter correction data into the array. It is necessary to turn o the HP/Agilent 8757 System Interface (controlled from the front-panel of the analyzer) so that the swept CW generator can temporarily control the power meter over GPIB. When the correction data entry process is complete, enable user atness correction and set the desired test port power level.

Using Detector Calibration Detector calibration is useful for characterizing and compensating for negative diode detectors used in external leveling. Detectors may be characterized by three operating regions as shown in Figure 1-12: the square law, the linear, and the transition region. The following steps use an HP/Agilent 437B to automatically characterize the operating regions and use this information to automatically compensate for the detector being used.
map 8, System, for the key sequence necessary to reach softkey Meter Adrs . 9. When the operation is complete, (a message is displayed) disconnect the power meter/sensor. The swept CW generator has stored the compensation information in its memory and is using it to calibrate the detector's output voltage relative to power.
Using the Tracking Feature Peaking Peaking is the function that aligns the output lter (YTM) so that its passband is centered on the RF output, in CW or manual-sweep mode. Use peaking to obtain the maximum available power and spectral purity, and best pulse envelopes, at any given frequency above 2.0 GHz. The YTM is inactive for the low band frequencies (10 MHz to 2.0 GHz). To peak at the present CW frequency: Press 4 5. Select Tracking Menu Peak RF Once .
ALC Bandwidth Selection The ALC bandwidth defaults at factory preset to the auto selection ALC Bandwidth Select Auto which selects the appropriate bandwidth (high or low) for each application. To make the bandwidth selection, the swept CW generator determines which functions are activated and uses the decision tree shown in Figure 1-23.

Programming GPIB, the General Purpose Interface Bus, is the instrument-toinstrument communication system between the swept CW generator Programming and up to 14 other instruments. Any instrument having GPIB capability can be interfaced to the swept CW generator, including non-HP instruments that have \GPIB," \IEEE-488," \ANSI MC1.1," or \IEC-625" capability (these are common generic terms for GPIB; all are electrically equivalent although IEC-625 uses a unique connector).
GPIB General Information Interconnecting Cables Figure C-2 shows the swept CW generator rear-panel GPIB connector and suitable cables, and describes the procedures and limitations for interconnecting instruments. Cable length restrictions, also described in Figure C-2, must be observed. Instrument Addresses Each instrument in an GPIB network must have a unique address, ranging in value from 00-30 (decimal).
In the programming explanations that follow, speci c examples are included that are written in a generic dialect of the BASIC language. BASIC was selected because the majority of GPIB computers have BASIC language capability. However, other languages can also be used.
Remote Remote causes an instrument to change from local control to remote control. In remote control, the front panel keys are disabled (except for the 4 5 key and the POWER switch), and the amber REMOTE annunciator is lighted. The syntax is: LOCAL where the device selector is the address of the instrument appended to the GPIB port number. Typically, the GPIB port number is 7, and the default address for the swept CW generator is 19, so the device selector is 719.
Local Local is the complement to REMOTE, causing an instrument to return to local control with a fully enabled front panel. The syntax is: Some BASIC examples: 10 LOCAL 7 10 LOCAL 719 which e ects all instruments in the network, or for an addressed instrument (address 19). Related statements used by some computers: RESUME Clear Clear causes all GPIB instruments, or addressed instruments, to assume a \cleared" condition, with the de nition of \cleared" being unique for each device.
Some BASIC examples: 10 CLEAR 7 10 CLEAR 719 to clear all GPIB instruments, or to clear an addressed instrument. Related statements used by some computers: RESET CONTROL SEND The preceding statements are primarily management commands that do not incorporate programming codes. The following two statements do incorporate programming codes, and are used for data communication. Output Output is used to send function commands and data commands from the controller to the addressed instrument.
A BASIC example: 100 OUTPUT 719; "programming codes" The many programming codes for the swept CW generator are listed in the \SCPI Command Summary" in Chapter 2. Related statements used by some computers: CONTROL CONVERT IMAGE IOBUFFER TRANSFER Enter Enter is the complement of OUTPUT, and is used to transfer data from the addressed instrument to the controller. The syntax is: ENTER is always used in conjunction with OUTPUT, such as: 100 OUTPUT 719; " . .. programming codes . .. " 110 ENTER 719; " . . .
Note Be careful when using byte-counting image speci ers. If the requested number of bytes does not match the actual number available, data might be lost, or the program might enter an endless wait state. The suppression of the EOL sequence is frequently necessary to prevent a premature termination of the data input. When not speci ed, the typical EOL termination occurs when an ASCII LF (line feed) is received.
Getting Started with SCPI Definitions of Terms This section of Chapter 1 describes the use of the Standard Commands for Programmable Instruments language (SCPI). This section explains how to use SCPI commands in general. The instrument command summary (at the end of this chapter) lists the speci c commands available in your instrument. This section presents only the basics of SCPI. If you want to explore the topic in greater depth, see the paragraph titled, \Related Documents.
Standard Notation This section uses several forms of notation that have speci c meaning. Command Mnemonics Many commands have both a long and a short form, and you must use either one or the other (SCPI does not accept a combination of the two). Consider the FREQuency command, for example. The short form is FREQ and the long form is FREQUENCY (this notation style is a shorthand to document both the long and short form of commands).
Commands and Responses," discusses message terminators in more detail. Response Examples Response examples look like this: 1.23 These are the characters you would read from an instrument after sending a query command. To actually pull them from the instrument into the controller, use the input statement appropriate to your application programming language. If you have problems, study the details of how the input statement operates.
Essentials for Beginners Program and Response Messages This subsection discusses elementary concepts critical to rst-time users of SCPI. Read and understand this subsection before going on to another. This subsection includes the following topics: These paragraphs introduce the Program and Response basic types of messages sent between Messages instruments and controllers. Subsystem Command Trees These paragraphs describe the tree structure used in subsystem commands.
Types of Commands Commands can be separated into two groups, common commands and subsystem commands. Common commands are generally not measurement related. They are used to manage macros, status registers, synchronization, and data storage. Common commands are easy to recognize because they all begin with an asterisk, such as *IDN?, *OPC, and *RST. Common commands are de ned by IEEE 488.2. Subsystem commands include all measurement functions and some general purpose functions.
Subsystem Command Trees The Command Tree Structure Most programming tasks involve subsystem commands. SCPI uses a hierarchical structure for subsystem commands similar to the le systems on most computers. In SCPI, this command structure is called a command tree . Figure 1-25. A Simplified Command Tree In the command tree shown in Figure 1-25, the command closest to the top is the root command , or simply the root . Notice that you must follow a particular path to reach lower level subcommands.
Colon When it is between two command mnemonics, a colon moves the current path down one level in the command tree. For example, the colon in MEAS:VOLT speci es that VOLT is one level below MEAS. When the colon is the rst character of a command, it speci es that the next command mnemonic is a root level command. For example, the colon in :INIT speci es that INIT is a root level command. Semicolon A semicolon separates two commands in the same message without changing the current path.
Figure 1-26. Proper Use of the Colon and Semicolon In Figure 1-26, notice how proper use of the semicolon can save typing.
Subsystem Command Tables These paragraphs introduce a more complete, compact way of documenting subsystems using a tabular format. The command table contains more information than just the command hierarchy shown in a graphical tree. In particular, these tables list command parameters for each command and response data formats for queries. To begin this exploration of command tables, consider a simpli ed SWEep subsystem for the swept CW generator in both the graphical and tabular formats. Figure 1-27.
the matching command. The parameter type is listed adjacent to each named parameter. More About Commands Query and Event Commands. Because you can query any value that you can set, the query form of each command is not shown explicitly in the command tables. For example, the presence of the swept CW generator :SWEep:DWELl command implies that a :SWEep:DWELl? also exists. If you see a table containing a command ending with a question mark, it is a query only command.
Example 1: "FREQuency:CW 5 GHZ; MULTiplier 2" The command is correct and will not cause errors. It is equivalent to sending: "FREQuency:CW 5 GHZ; :FREQuency:MULTiplier 2". Example 2: "FREQuency 5 GHZ; MULTiplier 2" This command results in a command error. The command makes use of the default [:CW] node. When using a default node, there is no change to the current path position. Since there is no command "MULT" at the root, an error results.
Examples of numeric parameters: 100 100. -1.23 4.56e3 -7.89E-01 +256 .5 no decimal point required fractional digits optional leading signs allowed space allowed after e in exponents use either E or e in exponentials leading + allowed digits left of decimal point optional Examples of numeric parameters in commands: 100 OUTPUT @Source;":FREQuency:STARt 1.0E+09" 110 OUTPUT @Source;":LIST:FREQuency 10.
Use discrete parameters to program settings that have a nite number of values. Discrete parameters use mnemonics to represent each valid setting. They have a long and a short form, like command mnemonics. You can use mixed upper and lower case letters for discrete parameters. Examples of discrete parameters: Discrete Parameters.
Reading Instrument Errors When debugging a program, you may want to know if an instrument error has occurred. Some instruments can display error messages on their front panels. If your instrument cannot do this, you can put the following code segment in your program to read and display error messages.
Example Programs The following is an example program using SCPI compatible instruments. The example is written in HP BASIC. This example is a stimulus and response application. It uses a source and counter to test a voltage controlled oscillator. Example Program Description. This example demonstrates how several SCPI instruments work together to perform a stimulus/response measurement. This program measures the linearity of a voltage controlled oscillator (VCO).

a 1 in the source Output Queue. The program waits at line 410 until the 1 returned by *OPC? is entered. Note that following each OUTPUT containing a query is an ENTER to retrieve the queried value. If you do not use paired OUTPUTs and ENTERs, you can overwrite data in the instrument Output Queue and generate instrument errors. 470 to 480: Disconnect output terminals of the instruments from the unit under test, and end the program.
Details of Commands and Responses In This Subsection This subsection describes the syntax of SCPI commands and responses. It provides many examples of the data types used for command parameters and response data. The following topics are explained: Program Message These paragraphs explain how to properly Syntax construct the messages you send from the computer to instruments. Response Message These paragraphs discuss the format of messages sent from instruments to the Syntax computer.
a semicolon. You must always end a program message with one of the three program message terminators shown in Figure 1-29. Use , <^END>, or <^END> as the program message terminator. The word <^END>> means that EOI is asserted on the GPIB interface at the same time the preceding data byte is sent. Most programming languages send these terminators automatically. For example, if you use the HP BASIC OUTPUT statement, is automatically sent after your last data byte.
Figure 1-31. Simplified Common Command Syntax As with subsystem commands, use a to separate a command mnemonic from subsequent parameters. Separate adjacent parameters with a comma. Parameter types are explained later in this subsection. Response Message Syntax Figure 1-32 shows a simpli ed view of response message syntax. Figure 1-32. Simplified Response Message Syntax Response messages can contain both commas and semicolons as separators.
SCPI Data Types These paragraphs explain the data types available for parameters and response data. They list the types available and present examples for each type. SCPI de nes di erent data formats for use in program messages and response messages. It does this to accommodate the principle of forgiving listening and precise talking. Recall that forgiving listening means instruments are exible, accepting commands and parameters in various formats.
rounds the parameter. For example, if an instrument has a programmable output impedance of 50 or 75 ohms, you speci ed 76.1 for output impedance, the value is rounded to 75. If the instrument setting can only assume integer values, it automatically rounds the value to an integer. For example, sending *ESE 10.123 is the same as sending *ESE 10. Examples of numeric parameters: 100 100. -1.23 4.56e3 -7.89E-01 +256 .
Use discrete parameters to program settings that have a nite number of values. Discrete parameters use mnemonics to represent each valid setting. They have a long and a short form, just like command mnemonics. You can used mixed upper and lower case letters for discrete parameters. Discrete Parameters.
response data are decimal representations of integer values including optional signs. Most status register related queries return integer response data. Examples of integer response data: Integer Response Data. Integer 0 +100 -100 256 signs are optional leading + sign allowed leading sign allowed never any decimal point response data are similar to discrete parameters. The main di erence is that discrete response data return only the short form of a particular mnemonic, in all upper case letters.
Programming Typical Measurements In This Subsection This subsection illustrates how the general SCPI concepts presented in previous subsections apply to programming real measurements. To introduce you to programming with SCPI, we must list the commands for the swept CW generator. We will begin with a simpli ed example. Using the Example Programs The example programs are interactive. They require active participation by the operator.
Use of the Command Tables In Table 1-4, notice that a new column titled \Allowed Values" has been added to the command table. This column lists the speci c values or range of values allowed for each parameter. A vertical bar (j) separates values in a list from which you must choose one value. The commands listed in the table are only part of all the available SCPI commands of the swept CW generator. For a complete listing of the programming codes see \SCPI Command Summary" in Chapter 2. Table 1-4.
Table 1-4.
GPIB Check, Example Program 1 This rst program is to verify that the GPIB connections and interface are functional. Connect a controller to the swept CW generator via an GPIB cable. Clear and reset the controller and type in the following program: 10 20 30 40 50 60 70 80 90 Source=719 ABORT 7 LOCAL Source CLEAR Source REMOTE Source CLS PRINT "The source should now be in REMOTE." PRINT "Verify that the 'REMOTE' LED is on.
When the swept CW generator is in REMOTE mode, all the front panel keys are disabled except the LOCAL key. But, when the LOCAL LOCKOUT command is set on the bus, even the LOCAL key is disabled. The LOCAL command, executed from the controller, is then the only way to return all (or selected) instruments to front panel control. Continue example program 1.
9. Attempt to change the start frequency and press 4 5. Verify that this is impossible. 10. Now press the swept CW generator 4 5 key and verify that still no action is taken. 11. Execute a \continue" on the controller. With the controller displaying \LOCAL mode", verify that the swept CW generator REMOTE LED is o . Also verify that all sweep functions now can be modi ed via the front panel controls. Note that the swept CW generator 4 5 key produces the same result as programming LOCAL 719 or LOCAL 7.
Setting Up A Typical Sweep, Example Program 3 In swept operation, the swept CW generator is programmed for the proper sweep frequency range, sweep time, power level, and marker frequencies for a test measurement. This program sets up the swept CW generator for a general purpose situation. The instrument is the same as in program 1.
110: Set the sweeptime to 500 ms. Notice that upper/lower case in commands does not matter. Also spaces before the su x (\MS") are not required in SCPI. 120 and 130: Set markers 1 and 2 to a xed value. Notice that the value for marker 2 does not end with a frequency su x. Hertz is a default terminator and is understood. 140: Wait until the source has completed setting up the commands that have been sent so far before turning on the output.
Queries, Example Program 4 The following example demonstrates the use of query commands and response data formats. Clear and reset the controller and type in the following program: 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 200 210 220 230 240 250 260 270 Source=719 ABORT 7 LOCAL 7 CLEAR Source REMOTE Source CLS OUTPUT Source;"*RST" OUTPUT Source;"POWER:LEVEL -5 dBm;STATE ON" OUTPUT Source;"FREQ:CW?" ENTER Source;F PRINT "Present source CW frequency is : ";F/1.
130: Enter the query response into a variable 'W'. Boolean responses are always '1' for ON and '0' for OFF. 140: Print the value of the POWER:STATE on the computer display. 150: Query the value of a discrete function (FREQ:MODE). 160: Dimension a string variable to contain the response. 170: Enter the response into A$. The response will be a string that represents the function's present value. 180: Print the value of A$ on the computer display. 190: Example usage of a MIN query.
Saving and Recalling States, Example Program 5 When a typical sweep, like example program 3, is set up, the complete front panel state may be saved for later use in non-volatile memories called registers 1 through 8. This can be done remotely as a part of a program.
90: Clear the computer display. 100: Print a message on the computer display. 110: Set up the source for a CW state. Note the combination of several commands into a single message. This single line is equivalent to the following lines: OUTPUT Source;"*RST" OUTPUT Source;"FREQ:CW 1.23456 GHZ" OUTPUT Source;"POWer:LEVel -1 DBM" 120: Save this state into storage register 2. 130 to 150: Print a message on the computer display and pause. 160: Recall the instrument state from register 1.
Looping and Synchronization, Example Program 6 Clear and reset the controller and type in the following program: 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 200 210 220 230 240 Source=719 ABORT 7 LOCAL 7 CLEAR Source REMOTE Source CLS OUTPUT Source;"*RST" OUTPUT Source;"FREQ:START 4 GHZ; STOP 5 GHZ; MODE SWEEP" OUTPUT Source;"POWER:LEVEL -1 DBM; STATE ON" OUTPUT Source;"SWEEP:TIME 1" OUTPUT Source;"*OPC?" ENTER Source;X REPEAT DISP "Enter number of sweeps to take : [0 to exit]"; INP
140 and 150: Prompt the operator for the number of sweeps to take. The number of sweeps to take is stored in the variable N. Enter 0 to quit the program. 160: Don't take any sweeps if N is less than 0. 170: Start a FOR/NEXT loop to take N sweeps. 180: Display the number of this sweep on the computer display. 190: Initiate a single sweep on the source and then wait until the pending operation is complete. Return a '1' when the sweep completes. 200: Enter the response to the *OPC? into the variable X.
Using the *WAI Command, Example Program 7 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 200 210 220 The following example illustrates the use of the *WAI command to cause the swept CW generator to perform a synchronous sweep.
140: Send a *WAI command to the source. This command causes the source to stop executing new commands until all prior commands and operations have completed execution. In this case, there is a sweep in progress, so no further commands will be executed until the sweep nishes. 150: Turn the RF output of the source ON. 160: Initiate a sweep on the source. 170: Send another *WAI to the source.
Using the User Flatness Correction Commands, Example Program 8 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 200 210 220 230 240 250 260 270 280 290 300 310 320 330 340 350 The following program interrogates the swept CW generator and an HP/Agilent 437B power meter for frequency and power information respectively. The swept CW generator is programmed to sweep from 2 to 20 GHz, with frequency-correction pairs every 100 MHz and +5 dBm leveled output power.

Programming the Status System In This Subsection This subsection discusses the structure of the status system used in SCPI instruments, and explains how to program status registers. An important feature of SCPI instruments is that they all implement status registers the same way. The status system is explained in the following paragraphs: General Status These paragraphs explain the way that status Register Model registers are structured in SCPI instruments.
There may or may not be a command to read a particular condition register. Transition Filter The transition lter speci es which types of bit state changes in the condition register will set corresponding bits in the event register. Transition lter bits may be set for positive transitions (PTR), negative transitions (NTR), or both. Positive means a condition bit changes from 0 to 1. Negative means a condition bit changes from 1 to 0. Transition lters are read-write.
Figure 1-34.
Programming the Trigger System In This Subsection Generalized Trigger Model This subsection discusses the layered trigger model used in SCPI instruments. It also outlines some commonly encountered trigger con gurations and programming methods. Trigger system topics are explained in the following paragraphs: Generalized Trigger These paragraphs explain the structure and components of the layered trigger model used in Model all SCPI instruments.
An instrument moves between adjacent states, depending on its internal conditions and the commands that you send. When you rst turn on power to an instrument, it is in the idle state. You can force the instrument to the idle state using :ABORt or *RST. The initiate and event detection trigger states are essentially a list of conditions that must be satis ed to reach the adjacent states.
Inside the Idle State. state. Figure 1-36 illustrates the operation of the idle Figure 1-36. Inside the Idle State Turning power on, or sending *RST or :ABORT forces the trigger system to the idle state. The trigger system remains in the idle state until it is initiated by INITiate:IMMediate or INITiate:CONTinuous ON. Once one of these conditions is satis ed, the trigger system exits downward to the initiate state. Note that *RST sets INITiate:CONTinuous OFF.
is on an upward path, and INITiate:CONTinuous is ON, it exits downward to an event-detection state. If the trigger system is on an upward path and INITiate:CONTinuous is OFF, it exits upward to the idle state. Inside Event Detection States. Figure 1-38 illustrates the operation of an arbitrary event detection state named . Typical are TRIGger, ARM, STARt, and STOP. Normal downward execution is controlled by the source command.
Figure 1-38.
Figure 1-39 illustrates the operation of the sequence operation state. The downward entrance to the Sequence Operation State signals that some instrument dependent action should begin at once. An upward exit is not allowed until the instrument signals that its action is complete. Note that complete can be de ned di erently for di erent instruments. For example, consider an instrument that can sweep a range of frequencies starting with f1 and ending with f2 .
Common Trigger Configurations In the previous paragraphs, you learned about the basic building blocks allowed in a SCPI trigger system. Generally, an instrument implements only a portion of the trigger features available. These paragraphs discuss the simplest con gurations: INIT and TRIG. The INIT Configuration The INIT con guration is the simplest possible trigger con guration. It uses no event detection states, and requires only two subsystems for programming, INITiate and ABORt.
The TRIG Configuration Instruments using the TRIG con guration include one event detection state named TRIG, and a corresponding TRIGger subsystem. And, all SCPI instruments implement the required INITiate and ABORt subsystems. Figure 1-41.
Description of Triggering in the 8360 L-Series Swept CW Generators The 8360 L-Series Swept CW Generators follow the SCPI model of triggering. It is a layered model with the structure shown in Figure 1-42. Figure 1-42. 8360 Simplified Trigger Model The process of sweeping involves all 3 of these states. The IDLE state is where the sweep begins. The IDLE state is left when the sweep is initiated. This can happen on a continuous basis (INIT:CONT ON) or on a demand basis (INIT:CONT OFF).
to jump to the next point when the signal becomes TRUE, therefore the rst point in the list or stepped sweeps is produced immediately upon starting the sweep. Receiving a trigger signal at the last point causes the IDLE state to be re-entered. Analog sweeps do not use the trigger signals during the sweep (although the trigger signals are needed to start the sweep as described). The ABORt command resets any sweep in progress and immediately returns the instrument to the IDLE state.
SOURce The SOURce command selects the trigger source for an event-detection state. Only one source can be speci ed at a time, and all others are ignored. Sending *RST sets SOURce to IMMediate.

Converting HP/Agilent 8340/41 Systems to 8360 L-Series Systems The following paragraphs are intended to assist you in converting existing HP/Agilent 8340/8341-based systems to 8360 L-Series swept CW generator-based systems. The 8360 L-series swept CW generator may be used where no modulation requirements are needed. Both manual and remote operational di erences are addressed.
Manual Operation Compatibility The 8360 L-Series swept CW generators are designed to be, in all but very few cases, a complete feature superset of the HP/Agilent 8340/8341 synthesized sweepers. The most notable omissions are that the 8360 L-Series does not accept: line triggers (ie.
System Connections Note The 8510 Network Analyzer The 8360 L-Series swept CW generator is compatible with any HP/Agilent 8510 network analyzer with rmware revision 4.0 or higher. To upgrade rmware for an existing 8510, an HP/Agilent 11575C Revision 4.0 Upgrade Kit or an HP/Agilent 11575D Revision 5.0 Upgrade Kit is required. HP/Agilent 8510 revisions prior to 6.
The HP/Agilent 8757C/E Scalar Network Analyzer The connections between the analyzer and the 8360 L-Series are similar to the connections between the analyzer and the HP/Agilent 8340/8341. The 8360 L-Series di ers from the HP/Agilent 8340/8341 in one connection only. It is unnecessary to connect the modulator drive signal from the analyzer to the source. The 8360 L-Series internally produces the 27.8 kHz modulated signal necessary for AC mode measurements on the analyzer.
Remote Operation Language Compatibility The 8360 L-Series swept CW generators support three GPIB programming languages; network analyzer language, SCPI (Standard Commands for Programmable Instruments), and M.A.T.E. CIIL language (Option 700). Network Analyzer Language 8360 L-Series network analyzer language is syntactically and semantically identical to the HP/Agilent 8340/8341 GPIB mnemonics.
Features not available in one of the language modes are marked by a horizontal line in the corresponding column. In the interest of brevity all SCPI commands have been listed in their most concise form. For a complete and comprehensive listing of the swept CW generator SCPI commands, refer to \SCPI COMMAND SUMMARY" in Chapter 2.

4 Operator's Check and Routine Maintenance WARNING Operator's Checks Service Information No operator serviceable parts inside. Refer servicing to qualified personnel. To prevent electrical shock, do not remove covers. The local operator's check (front panel use) allows the operator to make a quick check of the main swept CW generator functions prior to use. For delete front panel options of the Agilent 8360 L-Series, use the \Front Panel Emulator Software" to perform an operator's check.
Local Operator's Check Description Preliminary Check The preliminary check provides assurance that most of the internal functions of the swept CW generator are working. The main check provides a general check of the overall functions of the swept CW generator. No external equipment is needed. Each time the swept CW generator is turned on the swept CW generator performs a series of self tests on the internal CPU, power supplies, and front panel.
Main Check 5. 1. Press 4 2. Select Selftest (Full) . Check that all tests performed pass. 3. Press 4 5. If the display indicates a user preset was performed, select Factory Preset . Verify that the green SWEEP LED is blinking, the amber RF ON/OFF LED is on, and the red INSTR CHECK LED is o . 5. 4. Press 4 5. Select Tracking Menu . a. If the swept CW generator has Option 001, step attenuator, select Auto Track . Wait for the swept CW generator to nish peaking before continuing. b.
Routine maintenance consists of replacing a defective line fuse, cleaning the air lter, cleaning the cabinet, and cleaning the display. These items are discussed in the following paragraphs. Routine Maintenance Table 4-1. Fuse Part Numbers Voltage 115 V 230 V WARNING How to Replace the Line Fuse Note Fuse Part/Number 5 A 250 V 2110-0010 3 A 250 V 2110-0003 For continued protection against fire hazard, replace line fuse only with same type and rating.
How to Clean the Fan Filter Note The cooling fan located on the rear panel has a thin foam lter. How often the lter must be cleaned depends on the environment in which the swept CW generator operates. As the lter collects dust, the fan speed increases to maintain air ow (as the fan speed increases, so does the fan noise). If the lter continues to collect dust after the fan reaches maximum speed, air ow is reduced and the swept CW generator's internal temperature increases.
How to Clean the Cabinet WARNING To prevent electrical shock, disconnect the 8360 L-series swept CW generator from the mains before cleaning. Use a dry cloth or one slightly dampened with water to clean the external case parts. Do not attempt to clean internally. How to Clean the Display Filter The display of the swept CW generator is protected by a plastic display lter.

ALC BW Menu Speci es the coupling factor of an Coupling Factor external coupling device and causes the display to indicate the power at the coupler main output. Disables the ALC leveling circuits. Leveling Mode ALCoff Relative power level is controlled by means of the level DAC and attenuator.
4ALC5 Speci es the operating range of an external power meter used in an external leveling setup. This causes the swept CW generator display to agree with the power meter's power indication. The following paragraphs explain the power control (leveling) function of the swept CW generator in detail.
4ALC5 Figure A-1.
4ALC5 Note Two terms are used in the following discussions: power output and ALC level. Power output means actual output power including the e ects of the attenuator. ALC level means power levels before the attenuator. In swept CW generators without attenuators, these two terms are equivalent.
4ALC5 5, the ALC level and attenuator are set automatically to provide the most accuracy for the power requested. Uncoupled Operation. In some applications it is advantageous to control the ALC level and attenuator separately, using combinations of settings that are not available in coupled operation. In uncoupled mode ( Uncoupl Atten ), when the desired power output is set via 5, only the ALC level is changed. The attenuator setting 4 is changed via Set Atten .

Depends on value of CALibration:PMETer:RANGe. CALibration:PMETer:FLATness:NEXT? [lvl suffix] The parameter is the measured power that is currently produced by the swept CW generator. You must supply this parameter after measuring the power using an external power meter.
SCPI COMMAND SUMMARY pairs. This correction information is used to create a correction array that can be added to the internal calibration array. The correction entered is at the associated frequency. Frequencies in between frequency-correction pair values are determined by linear interpolation. If a value of START or STOP frequency is speci ed that is outside the limits of the speci ed frequencies, the correction applied at those points is 0 dB. After *RST, returns a MinFreq, 0 DB, MaxFreq, 0 DB response.
SCPI COMMAND SUMMARY Sets the GPIB address of the printer to use during some of the calibration procedures when the swept CW generator assumes GPIB control. *RST and power on do not e ect this command. The default is 1. The default value is set at memory initialization only. DIAGnostics:IORW , DIAGnostics:IORW? Performs a write to the I/O Device number speci ed in the rst and sets it to the value in the second .
SCPI COMMAND SUMMARY Signal Generator/8360 L-Series Swept CW Generator Service Guide to begin the troubleshooting procedure. DIAGnostics:TEST:CONTinue Causes the selftest execution to continue when paused for raw data examination. Does nothing in other conditions. DIAGnostics:TEST:DATA:DESC?

DIAGnostics:TEST:LOOP ON|OFF|1|0 DIAGnostics:TEST:LOOP? Selects and queries the test looping ON/OFF switch. Both commands are executable in selftest mode. After *RST, the setting is 0. DIAGnostics:TEST:NAME? [] Queries the name of a selftest by number. If the number is not speci ed then an array of all the selftest names is returned.
SCPI COMMAND SUMMARY requested value. The start/stop frequencies are updated to re ect the changes based on the coupling equations. The swept CW generator uses \bumping" to move unspeci ed frequency parameters, but if the nal value of any of the frequency headers is the result of bumping, then an error is generated since the user is not getting what was speci ed. This means, to guarantee sequence independence requires sending the frequency pairs in a single message.
SCPI COMMAND SUMMARY FREQuency:MANual [freq suffix]|MAXimum|MINimum|UP|DOWN FREQuency:MANual? [MAXimum|MINimum] Sets and queries the manual frequency. This controls the output frequency in swept manual mode. The limits are START and STOP. *RST value is the same as FREQ:CENTER. See FREQ:CENTER for more information. FREQuency:MODE FIXed|CW|SWEep|LIST FREQuency:MODE? Sets and queries the switch that selects either swept, CW or list operation. *RST value is CW.

[MAXimum|MINimum] Sets and queries the amount of time to dwell at each frequency. The number of dwells can be queried with LIST:DWELl:POINts?. This dwell is the time after completing phaselock and turning RF on before changing to the next frequency. After *RST, the value is 100 s (MIN).
SCPI COMMAND SUMMARY LIST:MODE LIST:TRIGger:SOURce How the list is played back. AUTO IMMediate AUTO BUS AUTO EXTernal MANual Don't care Each new frequency point is stepped to automatically, after waiting the speci ed DWELl time. Wait for a or *TRG over the GPIB before advancing to the next frequency in the list. Wait for a signal to be received on the external input before advancing to the next frequency in the list. Only the list point speci ed by LIST:MANual is played back.
SCPI COMMAND SUMMARY be used, there is really only a single value for all the markers. *RST value is 2 dB. MARKer[n]:AOFF Sets all the markers to OFF at once. While [n] may be used, there is really only a single switch for all the markers. MARKer[n]:DELTa? , This query returns the di erence in frequency between the two speci ed marker numbers.
SCPI COMMAND SUMMARY Power Subsystem Any place where dBm is accepted as a su x, any level su x is accepted also. In the absence of a su x, the units are assumed to be as set by the UNIT:POW command. POWer:ALC:BANDwidth|:BWIDth [freq suffix]|MAXimum|MINimum POWer:ALC:BANDwidth?|:BWIDth? [MAXimum|MINimum] Sets and queries the ALC bandwidth. This is actually not continuously variable, so the input is rounded to the nearest possible switch position.
SCPI COMMAND SUMMARY state. Programming a speci c value for POWer:AMPLifier:STATE sets POWer:AMPLifier:STATE:AUTO to OFF. *RST value is ON. POWer:ATTenuation [DB]|MAXimum|MINimum|UP|DOWN POWer:ATTenuation? [MAXimum|MINimum] Sets and queries the output attenuation level. Note that when setting the attenuator level to 10 dB the output power is decreased by 10 dB. Programming a speci ed attenuation sets POWer:ATTenuation:AUTO OFF.
SCPI COMMAND SUMMARY POWer:OFFSet [DB]|MAXimum|MINimum|UP|DOWN POWer:OFFSet? [MAXimum|MINimum] Sets and queries the power o set. This function changes mapping of absolute power parameters on input to and output from the swept CW generator. Changing this does not a ect the output power of the swept CW generator. Only the displayed parameters and query responses are changed. The equation implied by this is: The entered or displayed power = Hardware Power + O set After *RST, the value is 0.
SCPI COMMAND SUMMARY The *RST value is 0. POWer:SLOPe:STATe ON|OFF|1|0 POWer:SLOPe:STATe? Sets and queries the power slope state. *RST value is 0. POWer:SPAN [DB]|MAXimum|MINimum|UP|DOWN POWer:SPAN? [MAXimum|MINimum] The coupling equations for power sweep are exactly analogous to those for frequency sweep. Power sweep is allowed to be negative, unlike frequency sweeps. *RST value is 0.
SCPI COMMAND SUMMARY Sets and queries the reference oscillator selection switch. The command to set the switch will cause ROSC:SOUR:AUTO OFF to be done also. The *RST value is automatically determined. ROSCillator:SOURce:AUTO ON|OFF|1|0 ROSCillator:SOURce:AUTO? Sets and queries the automatic reference selection switch. The *RST value is 1. STATus:OPERation:CONDition? Queries the Standard Operation Condition register.
SCPI COMMAND SUMMARY Sets and queries the Data Questionable SRQ Enable register. The STATus:PRESet value is 0. STATus:QUEStionable[:EVENt]? Queries the Data Questionable Event Register. This is a destructive read. STATus:QUEStionable:NTRansition STATus:QUEStionable:NTRansition? Sets and queries the Negative TRansition Filter for the Data Questionable Status Register. The STATus:PRESet value is 0.
SCPI COMMAND SUMMARY Sets and queries the instrument, whether it is in master or slave mode. This applies in a dual source mode. *RST value is MASTer. SWEep:DWELl [time suffix]|MAXimum|MINimum SWEep:DWELl? [MAXimum|MINimum] Sets and queries the amount of time in seconds that the instrument stays (dwell) at each step after reporting a source settled SRQ and pulsing the Trigger Out line low. This one value is used at each step when in the SWE:TRIG:SOUR IMM mode of a stepped sweep.
SCPI COMMAND SUMMARY or a digitally stepped sweep. In either case, all of the other sweep subsystem functions apply. *RST is ANALog. SWEep:MANual:POINt |MAXimum|MINimum SWEep:MANual:POINt? [MAXimum|MINimum] Sets and queries the step point number to go to and lock. The value is a unitless value that is limited between 1 and the number of points requested. This command has no e ect on the instrument unless: the sweep mode is set to manual and the sweep generation is set to stepped mode.
SCPI COMMAND SUMMARY SWEep:STEP [freq suffix]|MAXimum|MINimum SWEep:STEP? [MAXimum|MINimum] Sets and queries the size of each frequency step. :STEP is governed by the equation: STEP = SPAN/POINTS. If you change step size then the number of points will be changed to span/step and a Parameter Bumped execution error is reported. If span or points are changed, then STEP= SPAN/POINTS. The step sweep command creates a coupling with sweeptime also.
SCPI COMMAND SUMMARY SYSTem:ALTernate |MAXimum|MINimum SYSTem:ALTernate? [MAXimum|MINimum] Sets and queries the save/recall register number to alternate the foreground state of the instrument. The *RST value is 1. SYSTem:ALTernate:STATe ON|OFF|1|0 SYSTem:ALTernate:STATe? Sets and queries the state of the Alternate State function. *RST setting is OFF. SYSTem:COMMunicate:GPIB:ADDRess Changes the GPIB's (General Purpose Interface Bus) address. The *RST value is 19.
SCPI COMMAND SUMMARY frequency limits and multiplier will be altered accordingly. However, the leveling point is not changed (see POWer:ALC:SOURce). SYSTem:PRESet[:EXECute] Sets the instrument to its \local operation" state. This is the same as pressing the front panel \green" key. There is no corresponding query. SYSTem:PRESet:SAVE Saves the present state so it can be used whenever the command is executed or the front panel \green" key is pressed.
SCPI COMMAND SUMMARY subsystem. This event does not a ect any other settings in this subsystem. This command has no e ect unless the instrument is in the wait for trig state. If the swept CW generator is in the wait for trig state, it performs its trigger action. This is an event and has no *RST condition.
