External triggering
The instrument is triggered by the TRIGGER key or a pulse received from an external source.
After each measurement, the instrument provides an output pulse on the VM COMP (voltmeter
complete) terminal. This output pulse can be used to trigger another instrument to perform additional
operations.
A typical application for external triggering is to use the instrument with a switch system that also has
external triggering capability. The drawing below shows an automated test system to measure 10
DUTs.
The instrument is externally triggered to perform a measurement when a channel closes in the switch
system. The switch system then receives the voltmeter complete (VM COMP) pulse when the
measurement is complete which then closes the next channel. This handshake sequence between
the instrument and switch system continues until all the 10 DUTs are measured.
