• 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 17, “Waveform Generator,” starting on page 257.
The TRIG OUT connector also provides the User Cal signal. See "To perform user
calibration" on page 301.
