Page 9: Getting Started
Getting Started This programmer manual provides you with the information required to use GPIB commands to remotely control your instrument. With this information, you can write computer programs that will perform functions such as setting the front-panel controls, taking measurements, performing statistical calculations, and exporting data for use in other programs, such as spreadsheets.
Page 10 Getting Started The programmer manual is divided into the following major sections: Getting Started. This section introduces you to the programming information and provides basic information about setting up your instrument for remote control. Syntax and Commands. This section provides an overview of the command syntax that you use to communicate with the instrument and other general information about commands, such as how commands and queries are constructed, how to enter commands, constructed mnemonics, and argument...
Page 11: Setting Up Remote Communications
Getting Started Setting Up Remote Communications Before setting up the instrument for remote communications using the electronic (physical) GPIB interface, you should familiarize yourself with the following GPIB requirements: A unique device address must be assigned to each device on the bus. No two devices can share the same device address.
Page 12 Getting Started Setting the GPIB Address To function correctly, your instrument must have a unique device address. The default settings for the GPIB conﬁguration are: GPIB Address: 1 GPIB Mode: GPIB Talk/Listen DSA/CSA/TDS8X00/B Series Programmer Manual...
Page 13 Getting Started To change either of the GPIB settings, do the following: 1. Select User Preferences from the Utilities menu. 2. Select the GPIB Conﬁguration Tab. 3. Change the GPIB Address to a unique address. 4. Click OK. The instrument is now set up for bidirectional communication with your controller. Master/Slave Mode The DSA8200 is factory set to be a GPIB device (slave), allowing you to control the instrument via the GPIB port.
Page 14 To switch the instrument between these two modes, use the GPIB Device-Controller Utility found in the Windows Start menu under Programs > Tektronix DSA8200 > GPIB Device-Controller Utility. Starting this utility displays the TekGpibSwitcher screen which allows you to switch the instrument between the two modes.
Page 15: Command Syntax
Command Syntax You can control the operations and functions of the instrument through the GPIB interface using commands and queries. The related topics listed below describe the syntax of these commands and queries. The topics also describe the conventions that the instrument uses to process them. See the Command Groups topic in the table of contents for a listing of the commands by command group, or use the index to locate a speciﬁc command.
Page 16 Command Syntax Table 2-2: Command Message Elements Symbol Meaning <Header> This is 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. If the command is concatenated with other commands, the beginning colon is required.
Page 17: Clearing The Instrument
Command Syntax Queries Queries cause the instrument to return status or setting information. Queries have the structure: [:]<Header>? [:]<Header>?[<Space><Argument> [<Coma><Argument>]...] You can specify a query command at any level within the command tree unless otherwise noted. These branch queries return information about all the mnemonics below the speciﬁed branch or level.
Page 18: Command Entry
Command Syntax Command Entry The following rules apply when entering commands: You can enter commands in upper or lower case. 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).
Page 19 Command Syntax When concatenating commands and queries, you must follow these rules: 1. Separate completely different headers by a semicolon and by the beginning colon on all commands except the ﬁrst one. For example, the commands , can be concatenated TRIGger:MODe NORMal ACQuire:NUMAVg 10 into the following single command:...

Page 21 Command Syntax Histogram Statistics Commands can specify which Sigma value to return for histogram statistics as a mnemonic in the header. A Sigma is speciﬁed in this way: Speciﬁer Mnemonics Table 2-6: Histogram Statistics Speciﬁer Mnemonics Symbol Meaning SIGMA<x> A histogram statistics speciﬁer; <x> is either 1, 2, or 3. Magniﬁed Timebase Commands can specify which of two magniﬁed timebases to set or query as a mnemonic in the header.
Page 22 Command Syntax Math Waveform Commands can specify the mathematical waveform to use as a mnemonic in the header. Mnemonics Table 2-11: Math Waveform Mnemonics Symbol Meaning Math<x> A math waveform speciﬁer; <x> is 1 through 8. Reference Waveform Commands can specify the reference waveform to use as a mnemonic in the header.
Page 23: Argument Types
Command Syntax Argument Types Numeric Many instrument commands require numeric arguments. The syntax shows the format that the instrument returns in response to a query. This is also the preferred format when sending the command to the instrument though any of the formats will be accepted.
Page 24: Command Entry
Command Syntax Here are some invalid strings: (quotes are not of the same type) "Invalid string argument' (termination character is embedded in the string) "test<EOI>" Block Several instrument commands use a block argument form (see the following table).

Page 387: Status And Events
Status and Events The instrument provides a status and event reporting system for the GPIB interfaces. This system informs you of certain signiﬁcant events that occur within the instrument. The instrument status handling system consists of ﬁve 8-bit registers and two queues for each interface.
Page 388 Status and Events Table 3-1: SESR Bit Functions Function 7 (MSB) Power On. Shows that the oscilloscope was powered on. On completion, the diagnostic tests also set this bit. User Request. Indicates that an application event has occurred. *See preceding note. Command Error.
Page 389 Status and Events Table 3-2: SBR Bit Functions (cont.) Function ———— Not used. ———— Not used. ———— Not used. 1–0 Enable DESER, ESER, and SRER allow you to select which events are reported to the Status Registers and the Event Queue. Each Enable Register acts as a ﬁlter to a Status Register (the DESER also acts as a ﬁlter to the Event Queue) and can prevent information from being recorded in the register or queue.
Page 390: Queues
Status and Events *PSC Command The *PSC command controls the Enable Registers contents at power-on. Sending *PSC 1 sets the Enable Registers at power on as follows: DESER 255 (equivalent to a DESe 255 command) ESER 0 (equivalent to an *ESE 0 command) SRER 0 (equivalent to an *SRE 0 command) Sending *PSC 0 lets the Enable Registers maintain their values in nonvolatile memory through a power cycle.
Page 391: Event Handling Sequence
Status and Events Before reading an event from the Event Queue, you must use the *ESR? query to read the summary of the event from the SESR. This makes the events summarized by the *ESR? read available to the EVENT? and EVMSG? queries, and empties the SESR.
Page 392: Synchronization Methods
Status and Events Queue (2). If the corresponding bit in the ESER is also enabled (3), then the ESB bit in the SBR is set to one (4). 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).
Page 393 Status and Events The acquisition of the waveform requires extended processing time. It may not ﬁnish before the instrument executes the CURVe? query (see the following ﬁgure). This can result in incorrect curve values. To ensure that the instrument completes waveform acquisition before attempting to execute the CURVe? query, you can synchronize the program.
Page 394 Status and Events CURVE? Although *WAI is one of the easiest ways to achieve synchronization, it is also the most costly. The processing time of the instrument is slowed since it is processing a single command at a time. This time could be spent doing other tasks. The controller can continue to write commands to the input buffer of the instrument, but the commands will not be processed by the instrument until all operations in process are complete.
Page 395 Status and Events Serial Poll Method: Enable the OPC bit in the Device Event Status Enable Register (DESER) and the Event Status Enable Register (ESER) using the DESE and *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.

This is the simplest approach. It requires no status handling or loops. However, you must set the controller timeout for a longer period of time than that used by the acquisition operation.
