Trigger Commands
The digitizer trigger circuitry helps you locate the waveform you want to
view. The type of triggering used is edge triggering. Edge triggering
identifies a trigger condition by looking for the slope (rising or falling) and
voltage level (trigger level) on the source you select. Any input channel or
the external trigger input can be used as the trigger source. The
commands in this subsystem define the conditions for triggering.
: TRIGger:SWEep
Command
:TRIGger:SWEep {AUTO | TRIGgered}
Description The command selects the sweep mode, which defines how the capture of
digitized samples to memory or the ODI streaming is started.
AUTO Capture to memory or ODI streaming will start on trigger reception.
If a trigger event does not occur within 20 ms the digitizer automatically
forces a trigger.
TRIGgered Capture to memory or ODI streaming will start on trigger
reception. If no trigger occurs, capture to memory or ODI streaming will
not start.
Query :TRIGger:SWEep?
The query returns the current setting for the sweep mode.
Returned Format [:TRIGger:SWEep] {AUTO | TRIGgered}<NL>
: TRIGger:EDGE:SOURce
Command
:TRIGger:EDGE:SOURce {EXTernal | CHANnel<N>}
Description The command selects the source for trigger events.
<N> An integer, 1-4.
EXTernal Use the external trigger input.
CHANnel<N> Use an analog input channel.
Query :TRIGger:EDGE:SOURce?
The query returns the current setting for the trigger source.
Returned Format [:TRIGger:EDGE:SOURce] {EXTernal | CHANnel<N>}<NL>
