modulation analyzer
(unwanted AM on
the output wanted
frequency)
Wanted input signal = 70 dBµV; unwanted input signal modulated with 30% AM; VoA(IF) = unwanted output signal Vout when the wanted output
signal is modulated with 0.3% AM.
Measurement at 887.5 MHz: fwanted = 885.25 MHz (80 dBµV), funwanted = 889.75 MHz 30% modulated with 100 kHz, fosc = 931 MHz.
