R&S SMB Command Description
1407.0806.32 6.41 E-2
SOURce:INPut Subsystem
The SOURce:INPut subsystem contains the commands for configuring the inputs for external pulse
modulation signals.
The instrument trigger setting influences all sweeps (Instrument Trigger).
Command Parameters Default
unit
Remark
[SOURce:]INPut:PULM:IMPedance G50 | 1G0
[SOURce:]INPut:TRIGger:SLOPe POSitive | NEGative
[SOURce:]INPut:PULM:IMPedance G10 | 1G0
The commands set the impedance for external feed via the PULSE EXT input.
Parameters: 1G0
10 kohm to ground
G50
50 ohm to ground
Example:
INP:PULM:IMP G50
'the PULSE EXT input is set to 50 ohm to ground.
*RST value Resolution Options SCPI
1G0 - Device-specific
[SOURce:]INPut:TRIGger:SLOPe POSitive | NEGative
The command sets the active slope of an externally applied trigger signal at the INST TRIG inputs
(BNC connector at the rear of the instrument). The setting is effective for both inputs at the same
time.
Example:
INP:TRIG:SLOP NEG
'the active slope of the external trigger signal at the INST TRIG inputs is the
falling slope.
*RST value Resolution Options SCPI
POSitive - Device-specific
