configuring VCO input signal so it will be sensitive in PLL system
|
Hello,I have made of a system which is based on the article attached.
I tuned the YIG to the resonance of the resonator, then i measured the output of the IF on a scope as shown below. When I tuned to ph2 pase shifter i see the "error voltage" level shanges which need to go back to the YIG "FM" port as shown below. Also i need to make sure that the signal going back to the YIG is something which the YIG could make changes so It will be sensitive to the signal. How do i need to tune the phi2 phase shifter so I wull get a lock in the resonance frequency? /g/electronics101/photo/296358/3858955?p=Created%2C%2C%2C20%2C2%2C0%2C0 /g/electronics101/photo/296358/3858956?p=Created%2C%2C%2C20%2C2%2C0%2C0 /g/electronics101/photo/296358/3858957?p=Created%2C%2C%2C20%2C2%2C0%2C0
