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.
