5.4.2
Linearity Error (Internal Mixer Mode)
This section describes how to measure the linearity error: set a total of two different signal frequencies,
and take the difference between the signal generator and the frequency obtained from the FM Demod func-
tion for each frequency. The linearity error is measured using the delta marker function.
In the R3132 series, the frequency is phase locked on the signal generator’s 10 MHz reference signal.
