place the U8480 Series in the wait-for-trigger state.

Item Description/Default Range of values
source
Available trigger sources:
– BUS: The trigger source is a *TRG common command or the
TRIGger[1][:IMMediate] SCPI command.
– EXTernal: The trigger source is the trigger input in the U8480 Series
– HOLD: Triggering is suspended. The only way to trigger the U8480 Series is to use
TRIGger[1][:IMMediate].
– IMMediate: The trigger system is always true. If INITiate[1]:CONTinuous is
ON, the U8480 Series is continually triggering free (free run mode). If an
INITiate[1][:IMMediate] command is sent, a measurement is triggered and
then the U8480 Series returns to the idle state.
