:TRIGger:SOURce
Syntax :TRIGger:SOURce {BUS|EXTernal|MANUal}
Description Selects the trigger source.
Queries trigger source that you set for the instrument.
Remarks The default trigger source is MANUal.
The trigger sources include the following types:
BUS: When the load receives the remote triggering command (
:TRIGger) via the
interface, the load will perform one trigger operation.
EXTernal: The digital I/O interface on the rear panel of the load can be used to receive
the external trigger signal. When the external trigger is in effect, the load
will perform one trigger operation once a low pulse is received over the
trigger terminal. The trigger output signal over the digital I/O interface can
be used to trigger an external device, such as a digital oscilloscope, an
electronic load, and other products.
MANUal: In the local operation mode, press the TRAN key on the front panel, and
then one trigger operation is executed.
Example :TRIG:SOUR BUS /*Selects the Bus trigger source.*/
:TRIG:SOUR? /*Queries the selected trigger source.*/
