Witryna20 sty 2024 · Re: EG&G 5209 lock-in amplifier repair. The comparator output does not look good. This would be a lot of high frequency "noise". The circuit shows some hysteresis (feedback to the non inverting input) that should normally suppress these intermediate states - though the capacitor between the inputs kind of defeats it.
