LOCK-IN AMPLIFIER
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 µV 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
Configured with:
/92 - Standard IF
/94 - Internal Oscillator
/97 - Broadband frequency card (5Hz - 200kHz)
Other Options may be available if needed, contact Sales to discuss.
