The Wait-for-Trigger State
After you have configured the meter and selected a trigger source, you must place
the meter in the wait-for-trigger state. A trigger will not be accepted until the
meter is in this state. If a trigger signal is present, and if the meter is in the
“wait-for-trigger” state, the measurement sequence begins and readings are
taken.
The “wait-for-trigger” state is a term used primarily for remote interface
operation. From the front panel, the meter is always in the “wait-for-trigger” state
and will accept triggers at any time, unless a measurement is already in progress.
You can place the meter in the “wait-for-trigger” state by executing any of the
following commands from the remote interface.
MEASure?
READ?
INITiate
The meter requires approximately 20 ms of set-up time after you send a
command to change to the "wait-for-trigger" state. Any external triggers that
occur during this set-up time are ignored.
