The SR850 is a digital lock-in amplifier based on an innovative DSP (Digital
Signal Processing) architecture. The SR850 boasts a number of significant
performance advantages over traditional lock-in amplifiers—higher dynamic
reserve, lower drift, lower distortion, and dramatically higher phase
resolution. In addition, the CRT display and 65,536 point memory make it
possible to display and process data in a variety of formats unavailable with
conventional lock-ins.
Features:
1 mHz to 102.4 kHz frequency range
>100 dB dynamic reserve
0.001 degree phase resolution
Time constants from 10 Micros to 30 ks
(up to 24 dB/oct rolloff)
