Parameters:
<State> ON | OFF
If ON, the range of the trigger offset is limited considering the
acquisition time and the reference point. Thus the trigger cannot
be set outside the waveform diagram.
*RST: ON

TRIGger<m>:MODE <TriggerMode>
Sets the trigger mode which determines the behaviour of the instrument if no trigger
occurs.

Parameters:
<TriggerMode> AUTO | NORMal | FREerun
AUTO
The instrument triggers repeatedly after a time interval if the trigger
conditions are not fulfilled. If a real trigger occurs, it takes prece-
dence. The time interval depends on the time base.
NORMal
The instrument acquires a waveform only if a trigger occurs.
FREerun
The instrument triggers after a very short time interval - faster than
in AUTO mode. Real triggers are ignored
*RST: AUTO
TRIGger<m>:FORCe
If the acquisition is running in normal mode and no valid trigger occurs, forcing the trigger
provokes an immediate single acquisition. Thus you can confirm that a signal is available
and use the waveform display to determine how to trigger on it.
