238 Agilent X-Series Signal Generators SCPI Command Reference
Analog Modulation Commands
Pulse Modulation Subsystem–Option UNU and UNW and Option 320 ([:SOURce])
The optional variable <unit> accepts nS (nanoseconds) to S (seconds) with a resolution of 10 nS.
The range value is dependent on the pulse period (refer to the :PULM:INTernal:PERiod command).
Use DELay1 with the DOUBlet parameter and Delay1 and Delay2 with the ADOublet parameter (refer
to the :PULM:SOURce:INTernal command).
When “TRIGgered” is the pulse train trigger mode, then this value specifies the time after a trigger is
received before the first Pulse Train On Time starts (refer to the :PULM:INTernal:TRAin:TRIGger
command).
Example
:PULM:INT:DEL 200E-9
The preceding example sets the internal pulse delay to 200 nanoseconds.
*RST 0.00000000E000
Key Entry Pulse Delay
:PULM:INTernal:FREQuency
Supported All with Option UNW
[:SOURce]:PULM:INTernal:FREQuency <frequency>|MAXimum|MINimum|UP|DOWN
[:SOURce]:PULM:INTernal:FREQuency?
This command sets the pulse rate for the internally- generated square wave using the variable
<frequency>
. The command, used with the UP|DOWN parameters, will change the frequency by a
user- defined step value. Refer to the :PULM:INTernal:FREQuency:STEP command for setting the value
associated with the UP and DOWN choices.
This command is used when SQUare is the pulse modulation type. Refer to :PULM:SOURce command
for the pulse modulation type selection.
Example
:PULM:INT:FREQ 1MHz
The preceding example sets the square wave pulse rate to 1 megahertz.
*RST 4.00000000E002
Range 0.1Hz–10MHz
Key Entry Pulse Rate
:PULM:INTernal:FREQuency:STEP
Supported All with Option UNW
[:SOURce]:PULM:INTernal:FREQuency:STEP[:INCRement] <freq>|MAXimum|MINimum|DEFault
[:SOURce]:PULM:INTernal:FREQuency:STEP[:INCRement]?
Range Internal Free Run: depends on pulse period and pulse width settings
Internal Triggered, Adjustable Doublet, & Triggered Doublet: 70nS to (42 S - 10
nS - pulse width)
