Introduction to The commands in the TRIGger subsystem define the conditions for an :TRIGger internal trigger. Many of these commands are valid in multiple trigger

Commands modes.

The default trigger mode is :EDGE.

The trigger subsystem controls the trigger sweep mode and the trigger specification. The trigger sweep (see ":TRIGger:SWEep" on page 323) can be AUTO or NORMal.

•NORMal mode displays a waveform only if a trigger signal is present and the trigger conditions are met. Otherwise the oscilloscope does not trigger and the display is not updated. This mode is useful for

low- repetitive- rate signals.

•AUTO trigger mode generates an artificial trigger event if the trigger specification is not satisfied within a preset time, acquires unsynchronized data and displays it.

AUTO mode is useful for signals other than low- repetitive- rate signals. You must use this mode to display a DC signal because there are no edges on which to trigger.

The following trigger types are available (see ":TRIGger:MODE" on page 319).
