Query
Description Queries the present trigger state.
Syntax < Long > < Short >
:trigger:state? :trig:stat?
Return Parameter <NR1> Trigger state
0 Un-triggered
1 Triggered
Note This function is designed for triggering with slow
time-bases or for single shot events. This query
will return 0 before the trigger point and 1 after a
trigger point (if any).
However with quicker time-bases in auto mode, a
periodic waveform is constantly re-sampled and
thus re-triggered each time, resulting in the query
returning 0 before each trigger. Therefore with
quicker time bases, this will usually result in 0
being returned, even if the waveform is shown as
triggered.
Example :trigger:state?
0
Returns the current
trigger state as un-
triggered.
:TRIGger:SOURce
Set
Query
Description Selects the trigger source channel.
