RMS Dly Spr Thresh (dBm) (Channel Sounding)

Menu Path: Trace > Data > Sounding > Overall > Metrics

RMS Dly Spr Thresh is the threshold used to determine whether a sample in the impulse response contains a path. This threshold is automatically set as 3 * sigma of the noise distribution (assumes AWGN Additive White Gaussian Noise - Statistically random radio noise characterized by a wide frequency range with regards to a signal in a communications channel.). You can adjust this threshold with the RMS Delay Spread Threshold parameter.

When averaging is enabled, RMS Dly Spr Thresh is calculated from the averaged impulse response.
