The multimeter generates the voltmeter complete signal after it has sampled
the input for each reading. The length of time this low-going TTL signal is true
(low) depends on the aperture time and on the autozero mode as shown below.

The VXIbus trigger lines are open-collector TTL lines that remain in a
non-asserted (high) state until the voltmeter complete signal is sent.
•
More than one TTL output trigger line can be enabled at one time.
