Phase Err (Flex Frame)
(Phase Error) is the phase difference between the I/Q reference signal and the I/Q measured signal, averaged over all symbol points.
The magnitude of this error data is an indicator of the quality of the phase component of the modulated signal. For example, a very high phase error might indicate high incidental FM Frequency Modulation modulation on the signal.
The phase error shown in the Points/Symbol has no effect on this error data.
trace is computed only at the symbol times (the instant in time when symbols are detected). The computation does not include points between symbols. Therefore, the value ofThe
also shows the symbol that has the largest phase error (the peak phase error).See Also
