EG&G Princeton Applied Research 5207 /93 Lock-In Amp
Single-Phase Lock-in Amplifier
Computer-controllable unit with integral RS232C and IEEE-488 interfaces to allow total programmability
Controlled functions include sensitivity, averaging time constant, phase, operating frequency, offset, dynamic reserve, display mode, and others
Standard features include auto-phasing, auto-ranging, and sine-wave response
Both digital and analog displays
Full scale sensitivity is 1 uV to 5 Vrms
Input impedance is AC coupled (100 M shunted by 40 pF)
Input modes are single-ended and differential
Frequency range determined by plug-in cards from 5Hz to 200kHz
Common mode rejection is 120 dB maximum
