Command Description R&S SMB
1407.0806.32 6.74 E-2
[SOURce:]PULM:SOURce INTernal | EXTernal
The command selects the source for pulse modulation. Pulse"
Parameters: INTernal
The internally generated rectangular signal is used for the pulse modulation.
EXTernal
The signal applied externally via the PULS EXT connector is used for the
pulse modulation.
Example:
PULM:SOUR INT
'selects the internal modulation source.
PULM:STAT ON
'activates the pulse modulation.
*RST value Resolution Options SCPI
INTernal - Option R&S SMB-K22 (external pulse modulation)
and R&S SMB-K23 (internal pulse modulation)
Compliant
[SOURce:]PULM:STATe ON | OFF
The command activates/deactivates the pulse modulation. The pulse generator and the output of the
video/sync signal is activated automatically. Output of signal can be switched off with command
SOURce:PGEN:OUTPut:STATe OFF.
Example:
PULM:STAT ON
'activates pulse modulation with the modulation source selected under
SOURce:PULM:SOURce.
*RST value Resolution Options SCPI
OFF - Option R&S SMB-K22 Compliant
[SOURce:]PULM:TRIGger:EXTernal:IMPedance G50 | G10K
The command selects the impedance for external pulse trigger. The trigger is fed via the PULSE
EXT input
Example:
SOUR:PULM:TRIG:EXT:IMP G50
'selects 50 OHM as the trigger impedance for the external pulse trigger.
*RST value Resolution Options SCPI
G10K - Option R&S SMB-K22 Compliant
[SOURce:]PULM:TRIGger:EXTernal:SLOPe POSitive | NEGative
The command sets the polarity of the active slope of an applied trigger at the PULSE EXT
connector.
Example:
PULM:TRIG:EXT:SLOP NEG
'the pulse generator is triggered on the negative slope of the external trigger
signal.
*RST value Resolution Options SCPI
POSitive - Option R&S SMB-K22 and R&S SMB-K23 Device-specific
