Command Description R&S SMB
1407.0806.32 6.72 E-2
SOURce:PULM and PGEN Subsystem
The PULM subsystem contains the commands for checking the pulse modulation. The external signal is
input at the PULSE EXT connector. The connector can be used as trigger input for internal pulse
modulation. The polarity and input impedance of the connector can be selected.
The PGEN Subsystem contains the command for activating/deactivating the output of the video/sync
signal at the PULSE VIDEO connector.
The keyword SOURce is optional with commands and can be omitted.

[SOURce:]PGEN:OUTPut[:STATe] ON | OFF
The command switches on/off the output of the video/sync signal at the PULSE VIDEO connector at
the rear of the instrument.
Example:
PGEN:OUTP:STAT OFF
'deactivates output of video/sync signal
*RST value Resolution Options SCPI
OFF - Option R&S SMB-K23 Compliant
[SOURce:]PULM:DELay 20ns .. 1s
The command sets the pulse delay. The pulse delay determines the time that elapses after a trigger
event before pulse modulation starts. The pulse delay is not effective for double pulse generation.
Example:
PULM:DEL 13 us
'13 us elapse after a trigger before the first pulse is generated.
