Introduction to
:TRIGger
Commands
The commands in the TRIGger subsystem define the conditions for an
internal trigger. Many of these commands are valid in multiple trigger
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 451) 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.
