Audio Performance Verification Procedures
Analog Input to Analog
Output Gain Accuracy
Over Frequency
This test measu
res the Analog Audio Output level accuracy over the audio
frequency range, when using an Analog Input as the audio source.
Typical Operation Check. This test checks for typical operation. Typical values
are not guaranteed characteristics a nd are listed in the test record as pass/fail.
1. Set the waveform monitor to the factory presets. (See page 60, Restore the
Factory Presets.) If the audio tile is not selected, press the Display Select
4 button.
