User Manual 3162A/B
SCPI Command Reference 4-3
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.
Querying Parameter
Setting
Query the current value of most parameters by adding a question mark ( ? ) to
the command. For example, the following command sets the output function
to square:
SOUR:FUNC:SHAP SQR
Query the output function by executing:
SOUR:FUNC:SHAP?
Query Response
Format
The response to a query depends on the format of the command. In general,
a response to a query contains current values or settings of the generator.
Commands that set values can be queried for their current value. Commands
that set modes of operation can be queried for their current mode. IEEE-STD-
488.2 common queries generate responses which are common to all IEEE-
STD-488.2 compatible instruments.
SCPI Command
Terminator
A command string sent to the function generator must terminate with a <new
line> character. The IEEE-STD-488 EOI message is a <new line> character.
A <carriage return> followed by a <new line> is also accepted. Command
string termination always resets the current SCPI command path to the root
level.
