Agilent X-Series Signal Generators SCPI Command Reference 239
Analog Modulation Commands
Pulse Modulation Subsystem–Option UNU and UNW and Option 320 ([:SOURce])
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 command
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: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
Key Entry Incr Set
:PULM:INTernal:PERiod
Supported All with Option UNW
[:SOURce]:PULM:INTern
al:PERiod <period>|MAXimum|MINimum|UP|DOWN
[:SOURce]:PULM:INTernal: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: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:PWIDth[1]|2 command 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 4.00000000Eï€006
Range 30 nS – 42 S
Key Entry Pulse Period
:PULM:INTernal:PERiod:STEP[:INCRement]
Supported All with Option UNW
[:SOURce]:PULM:INTernal:PERiod:STEP[:INCRement] <value><unit>|UP|DOWN
[:SOURce]:PULM:INTernal:PERiod:STEP[:INCRement]?
This command sets the step value for the internal pulse period using the variable <value><unit>.
The step value, set with this command, is used with the UP and DOWN choices available in the
:PULM:INTernal:PERiod command.
