Freq Err (TD-SCDMA)
Freq Err (Composite Frequency Error) shows the composite signal carrier frequency-error relative to the VSA's center frequency. This parameter is displayed in Hertz and is the amount of frequency shift, from the VSA's center frequency, that the VSA must perform to achieve carrier lock.
Errors in RF frequency, LO frequency, or digitizer clock rate could all appear as carrier frequency error.
