• Mask— The pass/fail status is evaluated periodically. When the
evaluation of the testing period results in a failure, the trigger output
pulses high (+5 V). Otherwise, the trigger output remains at low
(0 V). See Chapter 14, “Mask Testing,” starting on page 187.
• Waveform Generator Sync Pulse— All of the waveform generator output
functions (except DC and Noise) have an associated Sync signal:
The Sync signal is a TTL positive pulse that occurs when the
waveform rises above zero volts (or the DC offset value).
See Chapter 15, “Waveform Generator,” starting on page 199.
The TRIG OUT connector also provides the User Cal signal. See "To
perform user calibration" on page 234.
