The

OUTPut

command subsystem enables you to route the multimeter's voltmeter
complete signal to the VXIbus TTL trigger lines.

•
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.
Aperture Time
320 ms (50 Hz)
267 ms (60 Hz)
20 ms (50 Hz)
16.7 ms (60 Hz)
2.5 ms (400 Hz)
•
The VXIbus trigger lines are open-collector TTL lines that remain in a
non-asserted (high) state until the voltmeter complete signal is sent.
