EG&G 5207 Lock-In Amplifier 5 Hz - 200 kHz

The model 5207 single phase is a computer-controllable instrument. Integral RS232C and IEEE-488 interfaces allow total programmability. Computer-controllable functions include sensitivity, averaging time constant, phase, operating frequency, offset, dynamic reserve, display mode, and others. Other standard features include auto-phasing, auto-ranging, and "sine-wave" response.
