Chan Error Vector Magnitude (1xEV-DO) (Reverse Direction Only)

Chan EVM (%rms) is the Root Mean Square (RMS) of the error vectors computed and expressed as a percentage of the square root of the mean power of the ideal signal (see EVM, Magnitude and Phase Error data results (%rms)). To the right of the EVM value is the symbol with the largest (or Peak) EVM (% Pk) and its value.

The error vector is the magnitude of the vector, at the detected symbol location for the specified code channel, which connects the I/Q reference-signal phasor to the I/Q measured-signal phasor as shown in the following figure:

This data result only applies to reverse link direction signals.
