SCPI Syntax Conventions
Programming the counters through their LAN, USB, and GPIB interface is
achieved using the Standard Commands for Programmable Instruments (SCPI)
control language. A typical example of the SCPI language syntax is shown for the
following MEASure command:
MEASure:FREQuency? [{<expected>|MINimum|MAXimum|DEFault}
[,{<resolution>|MINimum|MAXimum|DEFault}]][,<channel>]]
The programming conventions are as follows.
Command Keywords and Abbreviated Commands
Command keywords (e.g.
Upper case letters indicate the abbreviated spelling of the keyword or parameter.
Either the abbreviated form or the entire command/parameter must be used.
Optional Keywords and Parameters
Optional (implied) keywords and parameters are indicated by square brackets
(e.g.
optional parameter is not specified, a default value is used.
Separating Commands and Parameters and Linking SCPI Commands
A space must separate the last keyword and the first parameter. Commas (,)
separate multiple parameters. The '@' symbol must precede each counter
channel number and parentheses must enclose each channel:
MEAS:FREQ:RAT? 5E6,(@2),(@1)
Multiple Subsystems
commands within different subsystems (root nodes) must be separated by a
semicolon (;) and a colon (:). For example, the string:
INP:COUP AC;:TRIG:SOUR EXT
requires a semicolon and a colon because the subsystems/root nodes (INPut and
TRIGger) are not the same.
