Command Interface
In addition to being controlled and monitored by way of the screen interface,
the instrument can be controlled and monitored by means of SCPI commands.
For example, averaging can be disabled for the ACP measurement screen by
changing the Averaging setting to On in the Meas Setup > Settings menu. The
same thing can be done by sending the command
[:SENSe]:ACPower:AVERage:[STATe] OFF
Figure 4-19 Screen interface setting vs. SCPI command
In the SCPI command syntax, variables are indicated by angled brackets; for
example, a parameter specifying an amplitude in dBm might be represented in
the command syntax by the variable
<ampl>
, but in an actual command this
variable be replaced by an actual value, such as
-10
.
Where a command parameter must be one of a limited set of choices, the
alternatives are listed, with vertical lines separating the choices:
OFF|ON|0|1
.
The SCPI syntax allows for certain elements of a command to be omitted for
brevity. Where a command name is given in a mixture of upper-case and
lower-case letters, the lower-case letters are optional (for example,
AVERage
can be shortened to
AVER
). Also, any element that is enclosed in brackets is
optional (however, if you do include the optional element, omit the brackets).
This command:
[:SENSe]:ACPower:AVERage:[STATe] OFF
can be sent in its long format:
:SENSe:ACPower:AVERage:STATe OFF
Or it can be shortened by omitting lower-case characters:
:SENS:ACP:AVER:STAT OFF
Or it can be shortened further by omitting the bracketed elements:
ACP:AVER OFF
