Agilent X-Series Signal Generators SCPI Command Reference 245
Analog Modulation Commands
Pulse Modulation Subsystem–Option UNU and UNW and Option 320 ([:SOURce])
DOUBlet This command sets Trigger Doublet as the pulse modulation source. This produces
two pulses at the RF OUTPUT connector for each trigger event at the PULSE
connector. The first pulse follows the external trigger signal. The second pulse has
user- defined width and delay parameters.
GATEd This command sets Gated as the pulse modulation source. A pulse train with
user- defined period and width parameters occurs at the RF OUTPUT connector
when a valid gate signal is applied to the PULSE connector.
PTRain This selection produces an RF pulse train (up to 2047 distinct cycles) with
user- defined widths and delays at the RF OUTPUT connector when a valid trigger
signal occurs at the PULSE connector. The Pulse Train Trigger mode selection
determines when the pulse train is output.
Example
:PULM:SOUR:INT SQU
The preceding example selects an internal free- run square wave with a 50% duty cycle, as the pulse
modulation source.
*RST FRUN (Int Free–Run)
:PULM:STATe
Supported All with Option UNW
[:SOURce]:PULM:STATe ON|OFF|1|0
[:SOURce]:PULM:STATe?
This command enables or disables pulse modulation for the selected path.
When pulse modulation is enabled, the PULSE annunciator appears on the signal generator’s
front- panel display.
Example
:PULM:STAT ON
The preceding example enables the pulse modulation.
*RST 0
