Using TekVISA

TekVISA is Tektronix implementation of VISA (Virtual Instrument Software Architecture), an industry-standard communication protocol. It allows you to write programs using the RSA3400A Series SCPI command set to control the instrument through interfaces besides the built-in IEEE 488.2 port. Programs are written to execute on the local or remote controller. The RSA3400A Series implementation of TekVISA includes a subset of the TekVISA functionality offered on Tektronix oscilloscopes. The Virtual GPIB (GPIB8), GPIB, and LAN (VXI-11 protocol) interfaces are supported, but not the ASRL interface.

NOTE. The details on TekVISA concepts and operations are explained in the

TekVISA Programmer Manual. Refer to Installing TekVISA described below for accessing the files.

Be aware of the following points:

H If TekVISA is not installed or has not been activated, and you select

TekVISA as the connection mode, the instrument still attempts to connect to TekVISA. This does not hang up the instrument, but the GPIB port i s taken off-line until you select GPIB Port as the connection mode again.

Installing TekVISA

H Applications which are designed to execute locally on the instrument need to

share the Wi ndows processor with the measurement calculation software of the analyzer. If the controller application is very compute-intensive, it will slow down the analyzer application significantly.

The TekVISA tools are not installed when you receive the instrument. Use the following procedure to install the tools.

To use TekVISA, these conditions must be satisfied:

H Windows XP is used as the instrument’s operating system.

Instruments using Windows 98SE must be upgraded to Windows XP for TekVISA to operate properly.

H A TekVISA-compatible version of the analyzer application is installed and

running on the instrument. Version must be greater than 3.00.000.

H TekVISA is installed on the instrument. Version 2.03 is recommended.

Command Syntax

SCPI Commands and Queries

SCPI is a standard created by a consortium that provides guidelines for remote programming of instruments. These guidelines provide a consistent programming environment for instrument control and data transfer. This environment uses defined programming messages, instrument responses, and data format across all SCPI instruments, regardless of manufacturer. The analyzer uses a command language based on the SCPI standard.

The SCPI language is based on a hierarchical or tree structure (see Figure 2--1) that represents a subsystem. The top level of the tree is the root node; it is followed by one or more lower-level nodes.

TRIGger

SEQuence

POLarity

SOURceLEVel

Root node

Lower-level nodes

Figure 2- 1: Example of SCPI subsystem hierarchy tree

You can create commands and queries from these subsystem hierarchy trees. Commands specify actions for the instrument to perform. Queries return measurement data and information about parameter settings.

2- 2

RSA3408A Programmer Manual

Command Syntax

Creating Commands

Creating Queries

Query Responses

SCPI commands are created by stringing together the nodes of a subsystem hierarchy and separating each node by a colon.

In Figure 2--1, TRIGger is the root node and SEQuence, LEVel, POLarity, and SOURce are lower-level nodes. To create a SCPI command, start with the root node TRIGger and move down the tree structure adding nodes until you reach the end of a branch. Most commands and some queries have parameters; you must include a value for these parameters. If you specify a parameter value that is out of range, the parameter will be set to a default value. The command descriptions, which start on page 2--79, list the valid values for all parameters.

For example, TRIGger:SEQuence:SOURce EXT is a valid SCPI command created from the hierarchy tree in Figure 2--1.

To create a query, start at the root node of a tree structure, move down to the end of a branch, and add a question mark. TRIGger:SEQuence:SOURce? is an example of a valid SCPI query using the hierarchy tree in Figure 2 -- 1.

The query causes the analyzer to return information about its status or settings. When a query is sent to the analyzer, only the values are returned. When the returned value is a mnemonic, it is noted in abbreviated format, as shown in Table 2--2.

Table 2- 2: Query response examples

Query Response

:DISPlay:OVIew:SGRam:X:SPAN? 10.0E+6

:SENSe:AVERage:TYPE? RMS

A few queries also initiate an operation action before returning information. For example, the *CAL? query runs a calibration.

Parameter Types

Every parameter in the command and query descriptions is of a specified type. The parameters are enclosed in brackets, such as <value>. The parameter type is listed after the parameter and is enclosed in parentheses, for example, (discrete). Some parameter types are defined specifically for the RSA3000 S eries command set and some are defined by ANSI/IEEE 488.2-1987 (refer to Table 2--3).

Command Syntax

SCPI-defined Parameters. In addition to the ANSI/IEEE 488.2-1987-defined parameters, RSA3000 Series support the following SCPI-defined parameters.

H <NRf> for boolean

OFF|ON|0|1|<NRf>

You can use <NRf> for boolean parameter. The values other than zero (OFF) are regarded as one (ON).

H MAXimum and MINimum for numeric parameters

You can use MAXimum and MINimum for the numeric parameter <NRf>. The following example sets the trigger level to the maximum (100%).

:TRIGger[:SEQuence]:LEVel:IF MAXimum

The commands that have numeric parameters support the following query:

<header>? { MAXimum | MINimum }

The query command returns the maximum or minimum acceptable value for the command. For example,

:TRIGger[:SEQuence]:LEVel:IF? MAXimum

returns 100 indicating the maximum trigger level is 100%.

H UP and DOWN for numeric parameters

The [:SENse]:FREQuency:CENTer command (refer to page 2--1073) supports UP and DOWN for the numeric parameters. The increment/decrement of UP/DOWN is determined by one of these commands:

Special Characters

Abbreviating Commands,

Queries, and Parameters

The Line Feed (LF) character (ASCII 10), and all characters in the range of ASCII 127-255 are defined as special characters. These characters are used in arbitrary block arguments only; using these characters in other parts of any command yields unpredictable results.

You can abbreviate most SCPI commands, queries, and parameters to an accepted short form. This manual shows these short forms as a combination of upper and lower case letters. The upper case letters indicate the accepted short form of a command. As shown in Figure 2--2, you can create a short form by using only the upper case letters. The accepted short form and the long form are equivalent and request the same action of the instrument.

Command Syntax

Chaining Commands and

Queries

You can chain several commands or queries together into a single message. To create a chained message, first create a command or query, add a semicolon (;), and then add more commands or queries and semicolons until the message is complete. If the command following a semicolon is a root node, precede it with a colon (:). Figure 2--3 illustrates a chained message consisting of several commands and queries. The single chained message should end in a command or query, not a semicolon. Responses to any queries in your message are separated by semicolons.

:CALC:MARK:X 100;:SENS:AVER:STAT ON;:DISP:WAV:Y:PDIV?;:READ:SPEC:CFR?

First command Second command Second query

The response from this chained message

might be

Response from first query Response from second query

First query

Figure 2- 3: Example of chaining commands and queries

If a command or query has t he same root and lower-level nodes as the previous command or query, you can omit these nodes. In Figure 2--4, the second command has the same root node (TRIG:SEQuence) as the first command, so these nodes can be omitted.

Command Syntax

Unit and SI Prefix

If the decimal numeric argument refers to amplitude, frequency, or time, you can express it using SI units instead of using the scaled explicit point input value format <NR3>. (SI units are units that conform to the Systeme International d’Unites standard.) For example, you can use the input format 200 mV or

1.0 MHz instead of 200.0E--3 or 1.0E+6, respectively, to specify voltage or frequency.

Table 2--4 lists the available units:

Table 2- 4: Available units

Symbol Meaning

dB decibel (relative amplitude)

dBm decibel (absolute amplitude)

DEG degree (phase)

Hz her tz (frequency)

PCT percent (%)

s second (time)

V volt

The available SI prefixes are shown in Table 2--5 below:

Table 2- 5: Available SI prefixes

G T PE EX

SI prefix A F P N U M K MA

Corresponding power 10

When the unit is “Hz”, “M” may be used instead of “MA” so that the frequency can be represented by “MHz”.

-- 1 8

-- 1 5

-- 1 2

-- 9

-- 6

-- 3

You can omit a unit in a command, but you must include the unit when using a SI prefix. For example, frequency of 15 MHz can be described as follows:

15.0E6, 1.5E7Hz, 15000000, 15000000Hz, 15MHz, etc. (“15M” is not allowed.)

Note that you can use either lower or upper case units and prefixes. The following examples have the same result, respectively.

170mhz, 170mHz, 170MHz, etc. 250mv, 250mV, 250MV, etc.

Constructed Mnemonics

Some header mnemonics specify one of a range of mnemonics. For example, a channel mnemonic can be either CALCulate1, CALCulate2, CALCulate3, or CALCulate4. You use these mnemonics in the command just as you do any other mnemonic. For example, there is a :CALCulate1:MARKer:MODE command, and there is also a :CALCulate2:MARKer:MODE command. In the command descriptions, this list of choices is abbreviated as CALCulate<x>. The value of <x> is the upper range of valid suffixes. If the numeric suffix is omitted, the analyzer uses the default value of “1”.
