4-11 FM Verification
This section provides a manual procedure to verify the performance of the frequency and phase modulation of
the MG362x1A.
The test methodology is the RF output of the MG362x1A is modulated on and off while monitored on a
spectrum analyzer display. The FM accuracy is determined by measuring the delta of Carrier Wave
(FM/
M on and FM/
M off). This delta is converted to modulation index by applying Inverse Bessel Null,
Taylor Series and Newton’s Method for Finding Roots calculations. The modulation index is then converted to
the actual deviation or dB. These tests quantify how the modulating input signal affects the signal generator’s
RF output.
