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.

The trigger source is set to IMMediate on U8480 Series power-up.
The MEASure and CONFigure commands automatically set the trigger source to
IMMediate.
The READ? query or MEASure command should not be used if the trigger source is
set to HOLD.
TRIG:SOUR IMM This command configures the U8480 Series
for immediate triggering.
