:trigger:state?

:trig:stat?

Return Parameter

<NR1>

Trigger state

Un-triggered

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?

Returns the current

trigger state as un-

triggered.

:TRIGger:SOURce

Set

Query

Description

Selects the trigger source channel.
