WitrynaSpecifying Lock-in Amplifiers 2 Both the sinewave-responding and the squarewave-responding lock-in amplifiers, when locked to the reference frequency f and correctly phase-adjusted for maximum response, would indicate a reading of:-V = √2/2 volts = 0.707 volts This is the r.m.s. value of a 2 volt peak-to-peak sinewave. WitrynaTo allow perfect phase matching at the demodulator, lock-in amplifiers include comprehensive and flexible phase shifting circuitry which allows a phase shift of over 360 degrees to be introduced. The phase controls on the lock-in usually take the form of a continuously variable of 0-95 degrees and 3 fixed increments of 90 degrees giving 365
