• 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 15, “Mask Testing,” starting on page 239.
• Waveform Generator Sync Pulse— All of the waveform generator output
functions (except DC, Noise, and Cardiac) 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 16, “Waveform Generator,” starting on page 251.
The TRIG OUT connector also provides the User Cal signal. See "To
perform user calibration" on page 294.
