SR124 & SR2124 — Analog Lock-in Amplifiers

For over a half century, the lock-in amplifier has been the instrument of choice for measuring small AC signals in the presence of noise. Early instruments were designed with analog electronics, multi-gang mechanical switches, needle indicators, etc., and measurements were often monitored with chart recorders. Microprocessor based designs emerged in the 1980s, and by the early 1990s even the lock-in’s analog demodulators were replaced by high-resolution ADCs and digital signal processors (DSP).

SR510 & SR530 — 100 kHz Lock-in Amplifiers

The SR510 and SR530 are analog lock-in amplifiers which can measure AC signals as small as nanovolts in the presence of much larger noise levels. Both the single phase SR510 and the dual phase SR530 have low-noise voltage and current inputs, high dynamic reserve, two stages of time constants, and an internal oscillator.

SR810 — 100 kHz Lock-in Amplifier

The SR810 Lock-In Amplifier and SR830 Lock-In Amplifier provide high performance at a reasonable cost. The SR830 simultaneously displays the magnitude and phase of a signal, while the SR810 displays magnitude only.

Both instruments use digital signal processing (DSP) to replace the demodulators, output filters, and amplifiers found in conventional lock-ins.

SR830 — 100 kHz lock-in amplifier

The SR810 Lock-In Amplifier and SR830 Lock-In Amplifier provide high performance at a reasonable cost. The SR830 simultaneously displays the magnitude and phase of a signal, while the SR810 displays magnitude only.

Both instruments use digital signal processing (DSP) to replace the demodulators, output filters, and amplifiers found in conventional lock-ins.

SR844 — 200 MHz Lock-in Amplifier

The SR844 is the widest bandwidth lock-in amplifier available. It provides uncompromised performance with a frequency range of 25 kHz to 200 MHz and up to 80 dB of drift-free dynamic reserve. The SR844 includes the many features, ease of operation, and programmability that you’ve come to expect from SRS DSP lock-in amplifiers.

SR850 — 100 kHz DSP Lock-in Amplifier

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

SR860 — 500 kHz Lock-in Amplifier

The new SR860 Lock-in Amplifier is the latest in a line of innovative lock-ins from SRS. With unparalleled analog performance, sophisticated new digital signal processing features, a thoroughly modern, intuitive user interface, and a wide range of computer connectivity options, the SR860 is the ideal choice for any synchronous detection application.

SR865A — 4 MHz Lock-in Amplifier

The SR865A Lock-In Amplifier offers superb performance and outstanding value. With 4 MHz frequency range, time constants from 1 µs to 30 ks, very low noise front-end amplifiers, and a modern, intuitive user interface, the SR865A is the ideal choice for any synchronous detection application.
