Command Syntax

Command Syntax

This section contains information on the Standard Commands for Programmable
Instruments (SCPI) and IEEE 488.2 Common Commands you can use to
program your waveform analyzer.

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 waveform analyzer
uses a command language based on the SCPI standard.

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

Creating Commands





Figure 1–1: 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.

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

In Figure 1–1, OUTPUT is the root node and TTLTRG, STATE, POLARITY,
and SOURCE are lower-level nodes. To create a SCPI command, start with the
root node OUTPUT 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 generally set to a default value. The

Command Syntax

command descriptions, which start on page 2–1, list the valid values for all
parameters.

For example, OUTPUT:TTLTRG1:STATE ON is a valid SCPI command created
from the hierarchy tree in Figure 1–1.

Creating Queries

Parameter Types

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. OUTPUT:TTLTrg:STATe? is an example
of a valid SCPI query using the hierarchy tree in Figure 1–1.

Every parameter in the command and query descriptions is of a specified type.
The parameters are enclosed in brackets, such as <pattern>. The parameter type
is listed after the parameter and is enclosed in parentheses, for example,
(discrete). Some parameter types are defined specifically for the waveform
analyzer command set and some are defined by ANSI/IEEE 488.2-1992 (see
Table 1–1).

Command Syntax

Abbreviating Commands,

Queries, and Parameters

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 1–2, 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.

Figure 1–2: Example of abbreviating a command

NOTE. The numeric part of a command or query must always be included in the
accepted short form. In Figure 1–2, the “1” of “TTLTRG1” is always included
in the command or query.

Chaining Commands and

Queries

1–4

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 you are done. If
the command following a semicolon is a root node, precede it with a colon (:).
Figure 1–3 illustrates a chained message consisting of several commands and
queries. A semicolon is not required after the final end or query in a chained
message. Responses to any queries in your message are separated by semicolons.

IEEE 488.2 Common Commands

Description

Command and Query

Structure

ANSI/IEEE Standard 488.2 defines the codes, formats, protocols, and usage of
common commands and queries used on the interface between the controller and
the instruments. The waveform analyzer complies with this standard.

The syntax for an IEEE 488.2 common command is an asterisk (*) followed by a
command and, optionally, a space and parameter value. The syntax for an
IEEE 488.2 common query is an asterisk (*) followed by a query and a question
mark. All of the common commands and queries are listed in the last part of the
Syntax and Commands section. The following are examples of common
commands:

 *ESE 16

 *CLS

The following are examples of common queries:

 *ESR?

 *IDN?

Definition

Message Terminators

This manual may describe commands and queries using the Backus-Naur Form
(BNF) notation. Table 1–2 defines the standard BNF symbols:

T able 1–2: BNF symbols and meanings

Symbol Meaning

<ą> Defined element

::= Is defined as

| Exclusive OR

{ą} Group; one element is required

[ą] Optional; can be omitted

.ă.Ă. Previous element(s) may be repeated

(ą) Comment

This manual uses <EOM> (End of message) to represent a message terminator.

Symbol Meaning

<EOM> 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 waveform analyzer always terminates messages
with LF and EOI. It allows white space before the terminator.

Constructed Mnemonics

Some header mnemonics specify one of a range of mnemonics. For example, a
channel mnemonic can be either INP1, INP2, INP3, or INP4. You use these
mnemonics in the command just as you do any other mnemonic. For example,
there is a INP1:FILT command, and there is also an INP2:FILT command. In the
command descriptions, this list of choices is abbreviated as INP<n>.

Command Syntax

Block Arguments

Several waveform analyzer commands use a block argument form:

Symbol Meaning

<NZDig> A non-zero digit character, in the range 1–9
<Dig> A digit character, in the range 0–9
<DChar> A character with the hex equivalent of 00 through FF

hexadecimal (0 through 255 decimal)

<Block> A block of data bytes, defined as:

<Block> ::=
{ #<NZDig><Dig>[<Dig>...][<DChar>...]

| #0[<DChar>...]<terminator> }

<NZDig> specifies the number of <Dig> elements that follow. Taken together, the
<Dig> elements form a decimal integer that specifies how many <DChar>

elements follow. The #0 format is for blocks of indifinite length and an END
message termination is required.

Overview

This section describes each command and query in the waveform analyzer. The
commands are organized by subsystem groups and the commands in each group
are in alphabetical order. In Figure 2–1, each block is a root node and the
commands within a block are subsystems. For example, SENSe is a root node
and AVERage is a subsystem of the SENSe node.

AADVance Subsystem

AADVance AADVance?

Sets or queries the state of the auto-advance acquisition mode. In the auto-ad­vance mode the waveform analyzer acquires a sequence of data records for each
active channel. The delay between one acquisition record and the next one is
very short and is due only to the minimal re-arm time and any trigger holdoff
you set. Use the command AADVance:COUNt to set the number of records to
acquire. You cannot use acquisition modes average, envelope, or peak detect (set
using [SENSe:]AVERage command) when using the auto-advance acquisition
mode.

The auto-advance mode of acquisition affects all enabled channels (XTIM:VOLT
<n>). You cannot acquire one channel in the auto-advance mode and acquire
another with the normal acquisition mode.

AADVance Subsystem

Sets or queries the number of records to acquire in the auto-advance acquisition
mode. The maximum number of Auto-advance records that you can acquire
depends on the record length and the number of active channels. A setting of
zero (0) acquires enough records to fill the DSP memory, regardless of the
current acquisition system settings. MAXimum acquires enough records to fill
DSP memory based on the current acquisition settings. The distinction is that
with a change such as the number of active channels, the MAXimum COUNt
setting is not adjusted, whereas the zero COUNt setting adjusts to ensure
memory is just filled within the new conditions.

To determine the current value for MAX, first set all acquisition parameters. Set
AADV:COUN to MAX. Finally, query with AADV:COUN? to return the current
value for MAX.

zero (0) selects all acquisition records, beginning with :STARt, for transfer
regardless of the current acquisition system settings. MAXimum selects all
acquisition records for transfer based on the current acquisition settings. If you
change a setting, such as the number of active channels, the MAXimum setting
will not be adjusted, but a setting of zero will automatically adjust for the new

ARM:SOURce ARM:SOURce?

ARM Subsystem

Sets or queries the source that will arm the acquisition system. You can specify
only one source at a time and it is shared by all acquired channels. Setting the
arm source to BUS configures the event detector to accept and arm on either the
*TRG or the VXIbus word serial <Trigger> command. The ECLTrg and TTLTrg
sources provide normal and inverted access to the standard ECLT and TTLT
signals on the VXI P2 bus. TTLTrg<n> arms when the TTLT line is low.
ITTLTrg<n> arms when the TTLT line is high. The ECLTrg<n> arms when the
ECLT line is high. IECLTrg<n> arms when the ECLT line is low. EXT arms
when the EXT input is a TTL low.

EXTernal is the front-panel BNC connector labeled Arm Input. Setting the arm
source to IMMediate bypasses event detection and immediately arms the
acquisition system.

AVERage Subsystem

This section describes the commands in the [SENSe:]AVERage subsystem. See
Figure 2–5. These commands select and setup one of four acquisition modes:
normal, average, envelope, and peak detect. (Peak detect is available for
TVS600A models only.) All active channels are affected by the acquisition mode
selected. Averaging, peak detecting, and enveloping occur in the acquisition
system before waveform records are passed to the CALC blocks. See Figure 2–6.

AVERage Subsystem

AVERage AVERage?

Sets or queries whether the waveform analyzer performs averaging during
acquisition. When the setting is off, the aquisition mode is normal; when on, the
acquisition mode is either average, envelope or peak detect, depending on the
setting for AVERage:TYPE (see page 2–16). The AVERage setting affects all
channels. When averaging is on, the values returned from [SENSe:]DATA? are
averaged, enveloped or peak-detected. The raw, unaveraged data is not available.

AVERage Subsystem

Sets or queries the number of acquisition records to average. Averaging reduces
signal noise by approximately 3 dB for each power of 2 increase (2, 4, 8, 16) in
the value of COUNt. For example, a COUNt setting of 8 will result in 3 dB less
noise than a COUNt of 4. The COUNt setting affects all active channels. The
count setting of one is intended for the PEAK DET type of averaging. PEAK
DET uses hardware to envelope the acquired data. The other modes will function
with a count of one, but with no added value.

AVERage Subsystem

AVERage:TYPE AVERage:TYPE?

Sets or queries the mode of acquisition to perform:
 SCALar (average), the default, averages each new sample point with the

corresponding point in the previous acquisition record.

 ENVelope generates a waveform record of interleaved MAX/MIN pairs of

sample points (the number of pairs is SWEep:POINts divided by two).

 PEAKdetect (TVS600A only) generates an array of MAX/MIN pairs, but

uses hardware peak detect to capture glitches between sampling intervals.

The AVERage:TYPE setting affects all channels.
Peak Detect hardware is not functional at a sample rate faster than 100 MS/s.

When peak detect is enabled on rates faster than 100 MS/s, the instrument will
function as if in ENVelope mode and will not issue any warning or error to that
effect.

This section describes the commands in the CALCulate subsystems which
process and perform measurements on acquisition records. These calculations are
typically performed immediately after the waveform analyzer completes
acquisition of the source. You can use CALCulate:IMMediate to reprocess and
measure an existing acquisition record. Figures 2–7 and 2–8 show the command
subblocks in the CALCulate subsystem.

CALCulate:DERivative:STATe CALCulate:DERivative:STATe?

Sets or queries whether to calculate a post-acquisition derivative on the selected
channel. When ON, the waveform analyzer calculates the derivative for every
point in an acquisition record. The result is a CALC<n> data record with the
same number of points as the original acquisition record.

When you perform a calculation with the command CALC:PATH:EXPRession,
the value of :STATe is ignored.

TVS600 & TVS600A Command Reference

CALCulate:FEED[1] CALCulate:FEED[1]?

CALCulate Subsystem

Sets or queries the source of data for the specified CALCulate block. The
calculations you set for a CALC block are performed on the source chosen with
this command when using the CALC:PATH command. The source may be from
any channel, reference, or a SENSe function; it is not tied to the CALC block
number. For example, the FEED1 for CALC2 could be “XTIM:VOLT 1” or
“XTIM:VOLT 3.” Additionally, more than one CALC block can operate on the
same source.

Trace names and function strings may be used interchangeably for the source
parameter <sense_func>. The query form always returns the function strings.

When you perform a calculation with the command CALC:PATH:EXPRession,
the value of :FEED1 can be referenced as “%1” (or by name; CHAN1, for
example) within the expression. Calculations are not performed on the :FEED1
source unless explicitly referenced in the CALC expression. See CALC:PATH
and CALC:PATH:EXPR commands.

Syntax

Parameters

When specifying calculations that require more than one waveform, such as gain,
phase, or delay, :FEED1 specifies the reference waveform and :FEED2 specifies
the target waveform. The target waveform is measured with respect to the
reference waveform; for example,1V in :FEED2 measured with respect to 2V in
:FEED1 yields a gain (attenuation) of .5.

CALCulate:PATH

Sets or queries a second source of data for the specified CALCulate block. The
second source is used when measurements that are based on two waveforms,
such as gain, phase, and delay, are specified using the CALCulate:WMList
command.

TVS600 & TVS600A Command Reference

CALCulate Subsystem

The source may be from any channel, reference or a SENSe function, it is not
tied to the CALC block number. For example, the FEED2 for CALC2 could be
“XTIM:VOLT 1” or “XTIM:VOLT 3.” Additionally, more than one CALC block
can operate on the same source.

Trace names and function strings may be used interchangeably for the source
parameter <sense_func>. The query form always returns the function strings.

When you perform a calculation with the command CALC:PATH:EXPRession,
the value of :FEED2 can be referenced as “%2” within the expression.

When defining SCPI model calculations that measure parameters based on two
waveforms (such as Gain and Delay), :FEED1 specifies the reference waveform
and :FEED2 specifies the target waveform. Also, the functions you set using
CALC:PATH only apply to the data source selected with FEED1. The source
selected by FEED2 is unaffected by the functions you select.

CALCulate:IMMediate CALCulate:IMMediate?

Sets or queries whether the specified CALCulate block will reprocess SENSe
data without reacquiring new data. The calculation is performed immediately
and, if the query form is sent, the resulting data is returned afterward. The query
form CALC:IMM? is semantically equivalent to CALC:IMM;DATA?. The
format of the resulting data is determined by the FORMat subsystem.

This command sets the ACQ_OPC pending flag. *WAI, *OPC, or *OPC? may
be used to synchronize the command.

Syntax

CALCulate:DERivative:STATe

Sets or queries a list of CALCulate functions to execute in the order listed upon
completion of acquisition. You specify the :PATH as a list of functions separated
by commas. The CALCulate subsystem performs the calculations in sequential
order on the source you define with CALCulate:FEED. CALCulate:PATH
supports simple post-processing measurements. When a measurement cannot be
expressed in a simple linear fashion, use the command CALC:PATH:EXPRes­sion.

Calculations based on the CALC:PATH command are based on the SCPI
calculation model. See the TVS600 & TVS600A Series Waveform Analyzers User
Manual for a description of the SCPI model.

CALCulate:PATH:EXPRession CALCulate:PATH:EXPRession?

Sets or queries a measurement expression using a “C like” programming
language. When you define an :EXPRession it will be calculated in place of any
calculation defined with the CALCulate:PATH command. The :EXPRession
command allows you to perform calculations that cannot be expressed in a linear
or sequential form.

Commands that control individual subblock operation also apply when the
subblock is called by the CALC:PATH:EXPRession. For instance, whether you
use CALC:PATH or CALC:PATH:EXPRession to call the high pass filter
(CALC:FILT:FREQ:HPAS), you must still use CALC:FILT:FREQ:HPASs
<cutoff> to set the lower limit frequency.

Sources to :EXPRession must be specified as trace names, such as CHAN1,
instead of as data aliases, such as “XTIM:VOLT 1”. The settings of CALCu­late:PATH and the :STATe commands of the subblocks are ignored. FEED1 and
FEED2 can be accessed as %1, %2 respectively. For more information, refer to

CALCulate:TRANsform:FREQuency:STATe CALCulate:TRANsform:FREQuency:STATe?

Sets or queries whether to perform a Fast Fourier Transform (FFT) on the
specified acquisition record to produce an equivalent frequency representation.
The FFT function produces a complex array of pairs of real and imaginary data
points. The number of data pairs in the resultant record is half the number of data
points in the original record.

You can convert the complex data produced by the FFT function into magnitude
