GPIB Command Structure
GPIB Command Structure
The GPIB commands follow the guidelines determined by the Standard
Commands for Programmable Instruments (SCPI) consortium. For
example, the
CONF:CHAN<wsp><number channels> command syntax
is used to change the number of channels to test in the IQS-12004B DWDM
Passive Component Test System.
In this example,
³
CONF identifies that the command is part of the SCPI CONFiguration
subset of commands.
³
CHAN is a keyword that define the function of the command.
³
<wsp> is included to indicate that a space is required (wsp stands for
white space).
³
<number channels> is the command parameter.
Keywords must be separated by a colon. A typical command would be
CONF:CHAN 4
This command instructs the system to test four channels in one
acquisition.
