:SOURce?

TRIGger:SOURce? returns “ BUS”, “ EXT”, “ IMM” or “ TTLTrg0 - 7” to show the present trigger source. The quoted string is sent to the output buffer.

Example Query the Trigger Source

TRIG:SOUR EXT	Trigger source is external BNC on multimeter
TRIG:SOUR?	front panel.
TRIG:SOUR?	Query multimeter to return trigger source
enter statement	setting.
enter statement	Enter quoted string into computer.
