SR850 Stanford Research Lock In Amplifier

Used
The SR850 is a 102 kHz Lock In Amplifier from Stanford Research. Amplify RF and Microwave signals to measure, test, and design circuits. Applications include radio communications, cellphones, EMI testing, and much more.

Additional Features:

  • Frequency range 1 mHz to 102.4 kHz >100 dB dynamic reserve Phase resolution 0.001 degree
  • Time constants from 10 µs to 30 ks (up to 24 dB/oct rolloff)
  • Auto-gain, -phase, -reserve and -offset
  • Data logging (up to 65k samples)
  • Smoothing, curve fitting & statistics
  • GPIB, RS-232 and 3.5" disk drive

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.
