Composite Frequency Error (1xEV-DO)

Composite Frequency Error (Freq Err) 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 Radio Frequency: A generic term for radio-based technologies, operating between the Low Frequency range (30k Hz) and the Extra High Frequency range (300 GHz). frequency, LO frequency or digitizer clock rate could all appear as carrier frequency error.
