Trigger control via GPIB

You need a separate GPIB command to start a measurement synchronized with
other instruments. This is done by sending the
(Group Execute Trigger) code. The MEASure? and READ? queries do not allow
you to do so, because such a setup causes a query error. With the
INITiate[:IMMediate] and FETCh? concept, it is possible to meet the requirements
of such applications.
Example:
CONFigure:AC
TRIGger:SOURce BUS
INITiate
TRG

FETCh:AC?
