Preface This programmer manual covers the TLS 216 Logic Scope. It provides information on operating your logic scope using the General Purpose Interface Bus (GPIB) interface. Section 1 Getting Started describes how to connect the logic scope to a controller. Section 2 Syntax and Commands describes the structure and content of the messages your program sends to the logic scope. Section 2 also describes what each command does and provides examples of how you might use them.
Preface viii TLS 216 Programmer Manual
Getting Started
Getting Started You can write computer programs that remotely set the TLS 216 Logic Scope front panel controls or take measurements and read those measurements for further analysis or storage. Your program sends commands and queries to operate the TLS and receive measurement data and status and event reports. TLS sends measurement data and status and event reports.
Getting Started GPIB Connector Port Figure 1–2: GPIB Connector Location If needed, you can stack GPIB connectors as shown in Figure 1–3.
Getting Started GPIB Requirements Observe these rules when you use your logic scope with a GPIB network: H Assign a unique device address to each device on the bus. No two devices can share the same device address. H Do not connect more than 15 devices to any one bus. H Connect one device for every 2 meters (6 feet) of cable used. H Do not use more than 20 meters (65 feet) of cable to connect devices to a bus. H Turn on at least two-thirds of the devices on the network while using the network.
Getting Started Setting the GPIB Parameters You need to set the GPIB parameters of the logic scope to match the configuration of the bus. Once you have set these parameters, you can control the logic scope through the GPIB interface. 1. Press the UTILITY (SHIFT DISPLAY) button to display the Utility menu. 2. Press the System button in the main menu until it highlights the I/O selection in the pop-up menu. (See Figure 1–5.) Figure 1–5: Selecting the I/O System in the Main Menu 3.
Getting Started Figure 1–6: Selecting the GPIB Address in the GPIB Configuration Side Menu 4. Press the Configure button in the main menu to display the GPIB Configuration side menu. (See Figure 1–6.) Other Communication Setups The procedure just listed configures the logic scope for bidirectional communication with your controller. In certain situations you may want to disable communications or send hard copies directly to a non-488.2 hard copy device.
Getting Started 1–6 TLS 216 Programmer Manual
Syntax and Commands
Command Syntax You can control the TLS 216 Logic Scope through the GPIB and RS-232-C interfaces using commands and queries. This section describes the syntax these commands and queries use. It also describes the conventions the logic scope uses to process them. The next section, entitled Commands, lists the commands and queries themselves. You transmit commands to the logic scope using the enhanced American Standard Code for Information Interchange (ASCII) character encoding.
Command Syntax A command message is a command or query name followed by any information the logic scope needs to execute the command or query. Command messages may contain five element types, defined in Table 2–2 and shown in the example in Figure 2–1. Table 2–2: Command Message Elements Symbol Meaning The basic command name. If the header ends with a question mark, the command is a query. The header may begin with a colon (:) character.
Command Syntax Commands Commands cause the logic scope to perform a specific function or change one of its settings. Commands have the structure: H [:][[]...] A command header consists of one or more mnemonics arranged in a hierarchical or tree structure. The first mnemonic is the base or root of the tree and each subsequent mnemonic is a level or branch off the previous one. Commands at a higher level in the tree may affect those at a lower level.
Command Syntax Clearing the Logic Scope You can clear the Output Queue and reset the logic scope to accept a new command or query by using the Device Clear (DCL) GPIB command. Command Entry Abbreviating Commands H You can enter commands in upper or lower case. H You can precede any command with white space characters. White space characters include any combination of the ASCII control characters 00 through 09 and 0B through 20 hexadecimal (0 through 9 and 11 through 32 decimal).
Command Syntax 3. Never precede a star (*) command with a colon: ACQuire:MODe ENVelope;*TRG Any commands that follow will be processed as if the star command was not there so ACQuire:MODe ENVelope;*TRG;NUMAVg 10 will set the acquisition mode to envelope and set the number of acquisitions for averaging to 10. 4. When you concatenate queries, the instrument concatenates all the responses into a single response message.
Command Syntax Message Terminators This manual uses (End of message) to represent a message terminator. Symbol Meaning Message terminator The end-of-message terminator may be the END message (EOI asserted concurrently with the last data byte), the ASCII code for line feed (LF) sent as the last data byte, or both. The logic scope always terminates messages with LF and EOI. It allows white space before the terminator. For example, it allows CR LF.
Command Syntax Measurement Specifier Mnemonics Channel Mnemonics Group Mnemonics Reference Waveform Mnemonics Waveform Mnemonics TLS 216 Programmer Manual Commands can specify which measurement to set or query as a mnemonic in the header. Up to four automated measurements may be displayed with each displayed waveform. The displayed measurements are specified in this way: Symbol Meaning A measurement specifier; is either [top], , , or [bottom].
Command Syntax Argument Types The argument of a command may be in one of several forms. The individual descriptions of each command tell which argument types to use with that command. Numeric Arguments Many logic scope commands require numeric arguments. The syntax shows the format that the logic scope returns in response to a query. It is also the preferred format when sending the command to the logic scope though it may accept any of the formats.
Command Syntax 4. You can include a quote character within a string simply by repeating the quote. For example, "here is a "" mark" 5. Strings can have upper or lower case characters. 6. If you use a GPIB network, you cannot terminate a quoted string with the END message before the closing delimiter. 7. A carriage return or line feed embedded in a quoted string does not terminate the string, but is treated as just another character in the string. 8.
Command Syntax Block Argument ALIas:DEFINE SETUp1",#231AUTOSet EXECute;:SELect:REF1 ON Block Header Specifies Data Length Specifies Number of Length Digits that Follow Figure 2–2: Block Argument Example Syntax Diagrams The syntax diagrams in this manual use the following symbols and notation: H Circles and ovals contain literal elements. You must send most elements exactly as shown.

Command Groups This section lists the TLS 216 Logic Scope commands in two ways. It first lists commands by functional groups. It then lists them alphabetically. (See Figure 2–4.) The functional group list, with brief command descriptions, starts below. The alphabetical list, with more detail on each command, starts on page 2–41. The logic scope GPIB interface conforms to Tektronix standard codes and formats and IEEE Std 488.2-1987 except where noted.
Command Groups Table 2–4: Acquisition Commands (Cont.) Header Description Start or stop acquisition system Acquisition control Alias Commands Alias commands let you define your own commands as a sequence of standard commands. This is useful when you use the same commands each time you perform a certain task, such as setting up measurements.
Command Groups Table 2–6: Application Menu Commands Header Description APPMenu Display the application menu APPMenu:LABel Return or remove all application menu button labels APPMenu:LABel:BOTTOM Label for a bottom menu button APPMenu:LABel:RIGHT Label for a side menu button APPMenu:TITLe Create a title for the application menu Calibration and Diagnostic Commands Calibration and Diagnostic commands let you start the built-in self-calibration and diagnostic routines of the logic scope.
Command Groups Cursor Commands Cursor commands provide control over cursor (caliper) display and readout.
Command Groups Display Commands Display commands let you change the graticule style, change the displayed intensities, turn off waveform display, display messages, and clear the menu. When you turn off waveform display, the instrument acquires and transmits waveforms but does not display them. The update rate is much faster when waveform display is off.

Command Groups Vertical Commands Vertical commands control the display of groups, of their channels and waveforms, and or reference waveforms. Groups vs. Channels The logic scope stores and displays waveforms in groups, which contain one or more channels each of which can contain one waveform. Use vertical commands to vertically position, offset, scale, and otherwise manipulate groups of waveforms.
Command Groups Table 2–19: Vertical Commands (Cont.
Command Groups Waveform Group Commands Waveform commands let you transfer waveform data points to and from the logic scope. Waveform data points are a collection of values that define a waveform. One data value usually represents one data point in the waveform record. When working with enveloped waveforms, each data value is either the min or max of a min/max pair. Before you transfer waveform data, you must specify the data format, record length, and waveform locations.
Command Groups The defined binary formats also specify the order in which the bytes are transferred. The four binary formats are RIBinary, RPBinary, SRIbinary, and SRPbinary. RIBinary is signed integer where the most significant byte is transferred first, and RPBinary is positive integer where the most significant byte is transferred first. SRIbinary and SRPbinary correspond to RIBinary and RPBinary respectively but use a swapped byte order where the least significant byte is transferred first.
Command Groups commands starting on page 2–322 for more information about the waveform preamble. Scaling Waveform Data Once you transfer the waveform data to the controller, you can convert the data points into voltage values for analysis using information from the waveform preamble. The program on the diskettes that come with this manual shows how you can scale data.
Command Groups Table 2–20: Waveform Commands TLS 216 Programmer Manual Header Description CURVe Transfer waveform data DATa Set waveform data format and location DATa:DESTination Set destination to the indicated channel DATa:ENCdg Select waveform data encoding method DATa:SOUrce Select source of CURVe? data DATa:STARt Set starting point in waveform transfer DATa:STOP Set ending point in waveform transfer DATa:TARget Set the destination to the indicated channel DATa:WIDth Set byte width

Command Descriptions You can use commands to either set instrument features or query instrument values. You can use some commands to do both, some to only set and some to only query. This manual marks set only commands with the words “No Query Form” included with the command name. It marks query only commands with a question mark appended to the header, and includes the words “Query Only” in the command name.
Command Descriptions Group Related Commands Syntax Acquisition ACQuire:NUMAVg, ACQuire:NUMENv, CURVe?, DATa:WIDth ACQuire:MODe { SAMple | AVErage | ENVelope } ACQuire:MODe? SAMple AVErage ENVelope ACQuire Arguments : MODe ? SAMple specifies that the displayed data point value is simply the first sampled value taken during the acquisition interval. In sample mode, all waveform data has 8 bits of precision.
Command Descriptions Group Related Commands Syntax Acquisition ACQuire:STATE ACQuire:NUMACq? ACQuire Returns Examples : NUMACq ? ACQUIRE:NUMACQ? might return 350, indicating that 350 acquisitions took place since an ACQUIRE:STATE RUN command was executed. ACQuire:NUMAVg Sets or queries the number of waveform acquisitions that make up an averaged waveform. Using this command is equivalent to setting the Average count in the Acquisition Mode side menu.
Command Descriptions ACQuire:NUMEnv Sets or queries the number of waveform acquisitions comprising an envelope waveform. Using this command is equivalent to setting the Envelope count in the Acquisition Mode side menu. Group Related Commands Syntax Acquisition ACQuire:MODe Arguments 0 is the number of waveform acquisitions, from 1 to 2000.
Command Descriptions ACQuire:STATE Starts or stops acquisitions. Using this command is equivalent to pressing the front-panel RUN/STOP button. If ACQuire:STOPAfter is set to SEQuence, other signal events may also stop acquisition. Group Related Commands Syntax Acquisition ACQuire:NUMACq? ACQuire:STOPAfter Arguments or or = 0 stops acquisitions.
Command Descriptions ACQuire:STOPAfter Tells the logic scope when to stop taking acquisitions. Using this command is equivalent to setting Stop After in the Acquire menu. Group Related Commands Syntax Acquisition ACQuire:MODe, ACQuire:STATE Arguments specifies that the run and stop state should be determined by the user’s pressing the front-panel RUN/STOP button.
Command Descriptions ALIas Turns command aliases on or off. This command is identical to the ALIas:STATE command. Group Alias Syntax Arguments or = 0 turns alias expansion off. If a defined alias label is sent when ALIas is OFF, execution error 102 will be generated: “syntax error, illegal use of alias name”. or 0 turns alias expansion on.
Command Descriptions Syntax ALIas:CATalog? ALIas Returns Examples : ? CATalog [,...] ALIAS:CATALOG? might return the string "SETUP1","TESTMENU1","DEFAULT", showing there are 3 aliases named SETUP1, TESTMENU1, and DEFAULT. ALIas:DEFINE Assigns a sequence of program messages to an alias label. These messages are then substituted for the alias whenever it is received as a command or query provided ALIas:STATE has been turned ON.
Command Descriptions NOTE. Attempting to give two aliases the same name causes an execution error. To give a new alias the name of an existing alias, you must first delete the existing alias. Examples ALIAS:DEFINE "ST1",":RECALL:SETUP 5;:AUTOSET EXECUTE;:SELECT:CH1 ON" defines an alias named “ST1” that sets up the logic scope. ALIAS:DEFINE? "ST1" might return :ALIAS:DEFINE "ST1",#239:RECALL:SETUP 5;:AUTOSET EXECUTE;:SELECT:CH1 ON. ALIas:DELEte (No Query Form) Removes a specified alias.
Command Descriptions Examples deletes all aliases. ALIas:DELEte:NAMe (No Query Form) Removes a specified alias. This command is identical to ALIas:DELEte. Group Alias Syntax Arguments Examples is the name of the alias to be removed. Using ALIas:DELEte:NAMe without specifying an alias causes an execution error. must be a previously defined alias.
Command Descriptions Arguments OFF or = 0 turns alias expansion off. If a defined alias is sent when ALIas:STATE is OFF, a command error (102) will be generated. ON or 0 turns alias expansion on. When the instrument receives a defined alias, it substitutes the specified command sequence and executes it. Examples ALIAS:STATE OFF turns the command alias feature off. ALIAS:STATE? returns 0 when alias mode is off.
Command Descriptions ALLOcate? (Query Only) Returns the number of data points allocated for all four reference memory locations. Group Save and Recall Syntax Examples might return , indicating that all 2,000 data points are allocated to reference memory location 1. ALLOcate:GROUP? (Query Only) Returns the number of data points allocated for all four reference memory locations.
Command Descriptions Syntax ALLOcate:GROUP:FREE? ALLOcate Returns Examples : GROUP : FREE ? is the approximate number of data points available. ALLOCATE:GROUP:FREE? might return 520 indicating that there are approximately 500 data points available for allocation. The extra 20 are used for administration purposes. ALLOcate:GROUP:REF Sets or queries the number of waveform data points for the specified reference location.
Command Descriptions Examples ALLOCATE:GROUP:REF2 1000 reserves 1,000 data points for REF2, specifying CH1 for first and last channels. ALLOCATE:GROUP:REF4 2000, 10, 14 reserves 2000 data points for reference group 4. The first channel is 10, the last channel is 14. ALLOCATE:GROUP:REF1? might return 500. APPMenu Displays the user-definable Application menu and the query returns the current Application menu labels and title. Using this command is equivalent to pressing the front panel APPLICATION button.

Status and Events
Status and Events The TLS 216 Logic Scope provides a status and event reporting system for the General Purpose Interface Bus (GPIB). This system informs you of certain significant events that occur within the logic scope. The logic scope status handling system consists of five 8-bit registers and two queues. This section describes these registers and components. It also explains how the event handling system operates and the program requests information from the logic scope.
Status and Events 7 6 5 4 3 2 1 0 PON URQ CME EXE DDE QYE RQC OPC Figure 3–1: The Standard Event Status Register (SESR) Table 3–1: SESR Bit Functions Bit Function 7 (MSB) PON (Power On). Shows that the logic scope was powered on. The completion of the diagnostic tests also sets this bit. 6 URQ (User Request). Shows that an Application menu button was pressed. 5 CME (Command Error). Shows that an error occurred while the logic scope was parsing a command or query.
Status and Events Table 3–2: SBR Bit Functions Enable Registers Bit Function 7 (MSB) Not used. 6 RQS (Request Service), obtained from a serial poll. Shows that the logic scope requests service from the GPIB controller. 6 MSS (Master Status Summary), obtained from *STB? query. Summarizes the ESB and MAV bits in the SBR. 5 ESB (Event Status Bit). Shows that status is enabled and present in the SESR. 4 MAV (Message Available). Shows that output is available in the Output Queue. 3–0 Not used.
Status and Events The Event Status Enable Register (ESER) is shown in Figure 3–4. It controls which types of events are summarized by the Event Status Bit (ESB) in the SBR. Use the *ESE command to set the bits in the ESER. Use the *ESE? query to read it. 7 6 5 4 3 2 1 0 PON URQ CME EXE DDE QYE RQC OPC Figure 3–4: The Event Status Enable Register (ESER) The Service Request Enable Register (SRER) is shown in Figure 3–5.
Status and Events Queues The logic scope status and event reporting system contains two queues: the Output Queue and the Event Queue. The Output Queue The logic scope stores query responses in the Output Queue. It empties this queue each time it receives a new command or query message after an End Of Message (EOM). The controller must read a query response before it sends the next command (or query) or it will lose responses to earlier queries. WARNING.
Status and Events Event Handling Sequence Figure 3–6 shows how to use the status and event handling system. In the explanation that follows, numbers in parentheses refer to numbers in Figure 3–6.
Status and Events When output is sent to the Output Queue, the MAV bit in the SBR is set to one (5). When a bit in the SBR is set to one and the corresponding bit in the SRER is enabled (6), the MSS bit in the SBR is set to one and a service request is generated (7). Synchronization Methods Although most GPIB commands are completed almost immediately after being received by the logic scope, some commands initiate processes requiring additional time.
Status and Events To ensure the logic scope completes waveform acquisition before taking the measurement on the acquired data, you can synchronize the program. Figure 3–8 shows the desired processing sequence. ACQUIRE:STATE ON Acquiring Waveform Data MEASUREMENT:IMMED:VALUE? Processing Time Figure 3–8: Processing Sequence With Synchronization You can use four commands to synchronize the operation of the logic scope with your application program: *WAI, BUSY?, *OPC, and *OPC?.
Status and Events processing a single command at a time. This time could be spent doing other tasks. The controller can continue to write commands to the logic scope input buffer, but the commands will not be processed by the logic scope until all operations in process are complete. If the input buffer becomes full, the controller will be unable to write more commands to the buffer. This can cause a time-out.
Status and Events *ESE commands. When the operation is complete, the OPC bit in the Standard Event Status Register (SESR) will be enabled and the Event Status Bit (ESB) in the Status Byte Register will be enabled.
Status and Events ACQUIRE:MODE NORMAL SAMPLE ACQUIRE:STOPAFTER SEQUENCE /* Enable the status registers */ DESE 1 *ESE 1 *SRE 32 /* Acquire waveform data */ ACQUIRE:STATE ON /* Set up the measurement parameters */ MEASUREMENT:IMMED:TYPE AMPLITUDE MEASUREMENT:IMMED:SOURCE CH1 /* Wait until the acquisition is complete before taking the measurement */ *OPC The Controller can now do different tasks such as talk to other devices. The SRQ, when it comes, interrupts those tasks and returns control to this task.
Status and Events Using the *OPC? Query The *OPC? query places a 1 in the Output Queue once an operation is complete. A time-out could occur if you try to read the output queue before there is any data in it.
Status and Events Messages Tables 3–3 through 3–9 list all the programming interface messages the logic scope generates in response to commands and queries. For most messages, a secondary message from the logic scope gives more detail about the cause of the error or the meaning of the message. This message is part of the message string, and is separated from the main message by a semicolon. Each message is the result of an event.
