0 None; EXTOUT is disabled
Input complete (1 µs pulse after A/D converter has integrated
1 each reading or, for direct- or sub-sampling, after the track and
hold has acquired the input signal)
Outputs a 1 µs pulse upon execution of the EXTOUT ONCE
2
command; the event then becomes OFF
Aperture waveform (a level indicating when the A/D converter is
3
making a measurement)
4 Burst complete (1 µs pulse following a group of readings)
Status event occurred (1 µs pulse whenever a status register event
5 occurs that has been enabled to assert the GPIB SRQ). (See
second Remark below.)
