PAR EG&G 5207 Lock In Amplifier Options 92 & 97
There is a small dent in the front panel, but overall, this unit is in Good Cosmetic Condition.
This Single-Phase Lock-in Amplifier detects and measures very small A.C. signals even when they are obscured by overwhelming noise and interference. Integral RS232C and IEEE-488 interfaces allow for computer control of sensitivity, averaging time constant, phase, operating frequency, offset, dynamic reserve, display mode, and more.
The unit includes auto-phasing, auto-ranging, and sine-wave response features as well as digital and analog displays. Full scale sensitivity is 1 V to 5 Vrms. Input impedance is AC coupled and frequency range is from 5Hz to 200kHz (determined by plug-in cards). Common mode rejection is 120 dB maximum.
