SCPI Command Reference 5-75
:SOURce <name>
:TRIGger[:SEQuence[1]]:SOURce <name> Specify measure event control source
Parameters <name> = IMMediate Pass operation through immediately
EXTernal Select External Triggering as event
TIMer Select timer as event

BUS Select bus trigger as event
Query :SOURce? Query programmed control source.
Description These commands are used to select the event control source. With
IMMediate selected operation immediately starts.
A specific event can be used to control operation. With EXTernal selected,
operation continues when an External Trigger is received.
With TIMer selected, the event occurs at the beginning of the timer interval,
and each time it times out. For example, if the timer is programmed for a 30
second interval, the first pass through the control source occurs immediately.
Subsequent scan events will then occur every 30 seconds. The interval for the
timer is set using the :TIMer command.
With MANual selected, the event occurs when the TRIG key is pressed.
With BUS selected, the event occurs when a GET or *TRG command is sent
over the bus.

Query :TIMer? Query programmed timer interval
Description These commands are used to set the interval for the timer. Note that the timer
is in effect only if it is the selected control source.
:SIGNal
:TRIGger[:SEQuence[1]]:SIGNal Bypass measure control source
Description This action command is used to bypass the specified control source when you
do not wish to wait for the programmed event. Remember that the instrument
must be waiting for the appropriate event when the command is sent.
Otherwise, an error occurs, and this command is ignored.
