When the evaluation ofthe 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, “MaskTesting,” starting on page 201.• Waveform Generator Sync Pulse— All of the waveform generator outputfunctions (except DC and Noise) have an associated Sync signal:The Sync signal is a TTL positive pulse that occurs when the waveform risesabove zero volts (or the DC offset value).See Chapter 17, “Waveform Generator,” starting on page 217.The TRIG OUT connector also provides the User Cal signal. See “To perform usercalibration" on page 257.Performing Service TasksThe Service Menu (under [Utility] > Service) lets you perform service-related tasks:• “To perform user calibration" on page 257• “To perform hard ware self test" on page 260• “To perform front panel self test" on page 261• “To display oscilloscope information" on page 261• “To display the user calibration status" on page 261For other information related to oscilloscope maintenance and service, see:• “To clean the oscilloscope" on page 261• “To check warranty and extended services status" on page 261• “To contact Keysight" on page 262• “To return the instrument" on page 262To perform user calibrationPerform user-calibration:
