Option Details
Parameter SCPI Notes
Key
KEY
The waveform is triggered when you press the front panel Trigger key
Bus
BUS
Enables triggering over GPIB, LAN, or USB using:
:SOURce:RADio:ARB:TRIGger:INITiate
External 1
EXTernal1
Enables triggering a waveform by an externally-applied signal
External 2
EXTernal2
Enables triggering a waveform by an externally-applied signal
Note: in EXM, trigger 2 is a bi-directional trigger port, so when trigger 2 has been
configured as OUTPUT type, selecting External 2 as the input trigger for the current
step generates an error
Note 2: in VXT model M9420A, triggers on an externally connected trigger source
marked Trigger 1 on the front panel
PXI
PXI
Enables triggering a waveform by a PXI backplane Line applied signal
Bus Trigger Command (Remote Command Only)
Used to initiate an immediate trigger event if "Trigger Source" on page 2293 is set to
BUS.
Remote
Command
:SOURce:RADio:ARB:TRIGger:INITiate
Example
:SOUR:RAD:ARB:TRIG:INIT
Sync to Trigger Source
There is a time interval (system processing time) between the trigger event and the
beginning of playing waveform. Turn on this control to compensate the system
latency at the cost of cutting off the beginning of the ARB. The figure below shows
the turn-on and turn-off behavior of the control.
