tanford Research SR830 DSP Dual Phase Lock-In Amplifier, 1 mHz to 102.4 kHz

The SR830 DSP Lock-In Amplifier provides high performance at a reasonable cost. The SR830 simultaneously displays the magnitude and phase of a signal. The instrument utilizes digital signal processing (DSP) to replace the demodulators, output filters, and amplifiers found in conventional lock-ins. The SR830 provides uncompromised performance with an operating range of 1 mHz to 102 kHz and 100 dB of drift free dynamic reserve.

Features:
•1 mHz to 102.4 kHz frequency range
•>100 dB dynamic reserve
•5 ppm/°C stability
•0.01 degree phase resolution
•Time constants from 10 µs to 30 ks (up to 24 dB/oct rolloff)
•Auto-gain, -phase, -reserve and -offset
•Synthesized reference source
•GPIB and RS-232 interfaces
