Freq Err (Custom IQ)
center frequency. This error data 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.
(Frequency Error) shows the carrier's frequency error relative to the VSA'sErrors 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 can all appear as carrier frequency error.
is computed using all points (including points between symbols).
This field will display no data when Frequency Estimation is set to .
If carrier lock is not occurring, try changing the Frequency Estimation setting from to .
