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
LowerĆlevel 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
WCA230A & WCA280A 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 2–35, 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.
WCA230A & WCA280A Programmer Manual

Command Syntax
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 WCA200 Series command
set and some are defined by ANSI/IEEE 488.2-1987 (refer to Table 2–3).

Command Syntax
SCPIĆdefined Parameters. In addition to the ANSI/IEEE 488.2-1987-defined
parameters, WCA200 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 2–259) supports
UP and DOWN for the numeric parameters. The increment/decrement of
UP/DOWN is determined by one of these commands:
[:SENse]:FREQuency:CENTer:STEP:AUTO
[:SENse]:FREQuency:CENTer:STEP[:INCRement]

Command Syntax
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.

Figure 2-2: Example of abbreviating a command
NOTE. The numeric suffix of a command or query may be included in either the
long form or short form; the analyzer will default to “1” if no suffix is used. In
Figure 2–2, the “3” of “CALC3” indicates that the command is directed to
View 3.

WCA230A & WCA280A Programmer Manual
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:XĂ100;:SENS:AVER:STATĂON;: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
100;1.2E+9
Figure 2-3: Example of chaining commands and queries
If a command or query has the 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.
:TRIG:SEQ:MODEĂNORM;:TRIG:SEQ:SLOPĂNEG;:TRIG:SEQ:POSĂ50

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:

Command Syntax
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 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:
H *ESE 16
H *CLS
The following are examples of common queries:
H *ESR?
H *IDN?

WCA230A & WCA280A Programmer Manual
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”.
Command Syntax
Table 2-6: Constructed mnemonics
Symbol Meaning
CALCulate<x> A view specifier where <x>=1to4.
DLINe<x> A horizontal display line specifier where <x>=1or2.
VLINe<x> A vertical display line specifier where <x>=1or2.
MARKer<x> A marker specifier where <x>=1or2.

Command Groups
This section lists the WCA200 Series analyzer commands in two ways. It first
presents them by functional groups. It then lists them alphabetically. The
functional group list starts below. The alphabetical list provides more detail on
each command and starts on page 2–35.
The WCA200 Series analyzers conform to the Standard Commands for
Programmable Instruments (SCPI) 1999.0 and IEEE Std 488.2-1987 except
where noted.
Items followed by question marks are queries; items without question marks are
commands. Some items in this section have a question mark in parentheses (?) in
the command header section; this indicates that the item can be both a command
and a query.
For the conventions of notation in this manual, refer to Command Syntax on

General Programming Procedure
You should generally use the following procedure to script a program:
1. Setting the measurement mode
Using an :INSTrument command, select a measurement mode to set the
basic conditions.
[Example] :INSTrument:SELect "SANORMAL"
Selects the normal spectrum analysis mode to set the basic conditions.
2. Setting the measurement item
Using a :CONFigure command, select a measurement item to set up the
analyzer to the defaults.
[Example] :CONFigure:SPECtrum:CHPower
Sets up the analyzer to the channel power measurement defaults.
3. Detailed settings
Use :SENSe commands to set details for the measurement session.
[Example] :SENSe:CHPower:BWIDth:INTegration 3MHz
Sets the channel power measurement range to 3 MHz.
4. Acquiring data
Use an :INITiate or :ABORt command to initiate or stop data acquisition.
[Example] :INITiate:CONTinuous ON
Initiates data acquisition in continuous mode.
To save or load the acquired data and settings, use an :MMEMory command.
[Example] :MMEMory:STORe:IQT "DATA1"
Saves the acquired data in file DATA1.IQT.
5. Obtaining the measurement results
Use a :FETCh or :READ command to obtain the measurement results.
[Example] :FETCh:SPECtrum:CHPower?
Returns the channel power measurement results.
6. Display
Use :DISPlay commands to set the display-related conditions.
[Example] :DISPlay:SPECtrum:X:SCALe:OFFSet 800MHz
Sets 800 MHz for the minimum (left) edge of the horizontal axis in the
spectrum view.
NOTE. A menu item grays out on the screen when the setting is prohibited or
unavailable. If you run the GPIB command corresponding to this menu item, an
execution error occurs. For example, when no waveform is displayed on the
screen, the scale-related commands are invalid.
