Phase Modulation
Phase modulation (
M) of the YIG-tuned oscillator RF output is achieved by summing an external or internal
modulating signal into the FM control path of the YIG loop. The external modulating signal comes from the
rear panel FM IN/FM IN input connector; the internal modulating signal comes from the B3 Function
Generator Module.
Circuits on the B3 FM Module adjust the modulating signal for the
M sensitivity selected, convert the
modulating signal to a
M signal by differentiation, and then sum it into the YIG loop FM control path. There,
it phase modulates the RF output signal by controlling the YIG-tuned oscillator’s FM (fine tuning) coil current.
