Performance Verification for OPT73 (FM Demodulation)
5.4.1
Offset Error (Internal Mixer Mode)
This section describes how to measure the difference between the frequency output from the frequency
generator and the frequency reading on FM Demod.
In the R3132 series, the frequency is phase locked on the signal generator’s 10 MHz reference signal.
