To whom it may concern,

I am to meassure the phase detector gain for the IC 74HC4046 I am using the phase comparator II which is said to be a phase frequency detector, I was told that in order to meassure the phase detector gain I have to inpur two signals close to each other in phase and frequency (knowing the phase difference), after that meassure the width of the output pulse and hence to calculate the phase detector gain, I am to divide the width of the output pulse by the phase difference at the input.

Thank you,

Best regards,

Francis
