Audio Analyzer Measurement Description
Expected Peak Voltage
The Expected Amplitude sets the analog audio clipping level and must be set. This voltage is always the
absolute peak audio input signal voltage expected at the AUDIO IN connectors, and must be in the range of
7.07 mV (5 mV ) to 20 V . Remember, measuring a 1-volt rms sinewave input signal would require a
peak rms peak
1.414 V expected voltage value to avoid clipping (over-driving) the input.
peak

De-Emphasis State

Set to On or Off (default) to enable or disable 750 microsecond de-emphasis.

Expandor Reference Level

Set value from 10 mV/kHz to 10 V/kHz, or Off (default). Entering a numeric value automatically turns the
state to On. Entering Off disables the expandor (state = off).

Trigger Source

Audio Analyzer measurements use immediate triggering and are continuously re-triggered by the analyzer
any time the Trigger Arm parameter is set to Continuous. Trigger timing is independent of any mobile protocol
signaling.
