SCPI and HS Command Reference 4-3
Some parameters are enclosed in square brackets ([ ]). The
brackets indicate that the parameter is optional and can be
omitted. The brackets are not sent with the command string. If
an optional parameter is not specified, the synthesizer uses a
default value.
Command
Separator
A colon ( : ) is used to separate a command keyword from a
lower level keyword as shown below:
SOUR:FUNC:SHAP
SIN
A semicolon ( ; ) is used to separate commands within the same
subsystem, and can also minimize typing. For example, sending
the following command string:
TRIG:SOUR:ADV INT;BURS ON;INT:RATE 5e-3
is the same as sending the following three commands:
TRIG:SOUR:ADV
INT
TRIG:BURS
ON
TRIG:INT:RATE
5e-3
Use the colon and semicolon to link commands from different
subsystems. For example, in the following command string, an
error is generated if both the colon and the semicolon are not
used.
OUTP:STATE
ON;:TRIG:STAT
ON
The MIN and MAX
Parameters
Substitute MINimum or MAXimum in place of a parameter for
some commands. For example, consider the following
command:
FREQuency
{<frequency>|MINimum|MAXimum}
Instead of selecting a specific frequency, substitute MIN to set
the frequency to its minimum value or MAX to set the frequency
to its maximum value.
