Unexpected Frequency Event
In Referenced Mode, the system knows the Reference Audio file that is being played on the Source DUT; therefore, the system knows which frequencies (tones) to expect at a given time. The Unexpected Frequency event is reported when a measured frequency deviates from an expected frequency by a specific percentage (determined by the negotiated parameters of the over-the-air audio stream).
The information reported with the Unexpected Frequency event is listed below:
- Info1: The measured frequency (Hz).
- Info2: The expected frequency (Hz).
- Msg: “SegID=N”, where N is a Segment Identifier indicating the expected segment.
