Agilent N5181A/82A MXG Signal Generators SCPI Command Reference 133
Analog Modulation Commands
Pulse Modulation Subsystem–Option UNU and UNW([:SOURce])
:PULM:INTernal[1]:FREQuency:STEP
Supported All with Option UNU and UNW
[:SOURce]:PULM:INTernal[1]:FREQuency:STEP[:INCRement] <freq>|MAXimum|MINimum|DEFault
[:SOURce]:PULM:INTernal[1]:FREQuency:STEP[:INCRement]?
This command sets the step value for the internally- generated square wave pulse rate.
This command is used when SQUare is the pulse modulation type. Refer to “:PULM:SOURce” on
page 135 for the pulse modulation type selection. Refer to “:PULM:SOURce” on page 135 for the pulse
modulation type selection. The step value, set with this command, is used with the UP and DOWN
choices in the :PULM:INTernal[1]:FREQuency command.
The step value set with this command is not affected by a power- on, preset, or *RST command.
Example
:PULM:INT:FREQ:STEP MIN
The preceding example sets the step value for the square wave pulse rate to 0.1 Hz, the minimum
rate.
Range 0.1Hz–10MHz
:PULM:INTernal[1]:PERiod
Supported All with Option UNU and UNW
[:SOURce]:PULM:INTernal[1]:PERiod <period>|MAXimum|MINimum|UP|DOWN
[:SOURce]:PULM:INTernal[1]:PERiod?
This command sets the pulse period for the internally–generated pulse modulation using the variables
<value><units>. The command, used with the UP|DOWN parameters, will change the pulse period by
a user–defined step value. Refer to the :PULM:INTernal[1]:PERiod:STEP[:INCRement] command for
setting the value associated with the UP and DOWN choices.
If the entered value for the pulse period is equal to or less than the value for the pulse width, the
pulse width changes to a value that is less than the pulse period. Refer to
“:PULM:INTernal[1]:PWIDth[1]|2” on page 134 for setting the pulse width.
Example
:PULM:INT:PER .5S
The preceding example sets the period of the internally–generated pulse to 500 milliseconds.
*RST +4.00000000E−006
Range 30nS–42S
