Response message: HOLD, MAN, IMM, BUS, TLIN, EXT or TIM
Description These commands are used to select the event control source the specified layer. With HOLD se-
lected, operation will stop and wait indefinitely in the specified layer. While in HOLD, operation
can be continued by sending the :IMMediate command or the :SIGNal command. Keep in mind
however, that if the layer count is >1, HOLD will again be enforced when operation loops back
around.
With IMMediate selected (do not confuse :SOURce IMMediate with :IMMediate), operation
will immediately pass through the specified layer.
NOTE
With the Immediate trigger source seleted, a “trigger ignored” message will
be displayed if an external trigger is sent to the Model 2001 or a manual trig-
ger (ie., pressing TRIG key) occurs. The external or manual trigger is not used
(ignored).
A specific event can be used to control operation through a layer. With BUS selected, operation
will continue when a GPIB trigger (GET or *TRG) is sent. With TLINk selected, operation will
continue when an input trigger via the Trigger Link is received. With EXTernal selected, opera-
tion will continue when an External Trigger is received.
A TIMer event is available for the scan and measure layers. With TIMer selected for the speci-
fied layer, the event occurs at the beginning of the timer interval, and every time it times out. For
example, if the measure layer timer is programmed for a 30 second interval, the first pass
through the measure layer control source will occur immediately. Subsequent scan events will
then occur every 30 seconds. The interval for the timer is set using the :TIMer command.
