SIGNAL RECOVERY

Signal Recovery designs, manufactures and sells lock-in amplifiers, signal averagers, amplifiers, light choppers, signal multiplexers, and specialized counters

SIGNAL RECOVERY is part of AMETEK Advanced Measurement Technology, and designs, manufactures and sells lock-in amplifiers, signal averagers, amplifiers, light choppers, signal multiplexers, and specialized counters. We have been involved in this business since one of our constituent companies, Princeton Applied Reasearch, invented the lock-in amplifier, giving us a unique insight into the areas of research in which our products are used and the ability to really help customers solve difficult measurement problems.

Analogue Lock-In Amplifiers

Model 5105 Dual-Phase Analogue Lock-in amplifier

Model 5105 Dual-Phase Analogue Lock-in amplifier

The model 5105 is a compact dual-phase lock-in amplifier ideal for those signal recovery applications not demanding the performance offered by more sophisticated instruments in the SIGNAL RECOVERY range. It does not incorporate controls for manual operation but instead is operated entirely via an RS232 interface using simple ASCII character string commands. This approach allows the unit to be located closer to the signal source than is the case with PC card based instruments, thereby improving performance.

Over the past few decades, the Signal Recovery Models 5209 (single-phase) and 5210 (dual-phase) have become the benchmark lock-in amplifiers against which others are judged. They are widely referenced in technical publications describing a diverse range of research applications including optical, electrochemical, electronic, mechanical and fundamental physical studies.

Preamplifiers

Model 5113 Low-Noise Voltage Preamplifier

Model 5113 Low-Noise Voltage Preamplifier

The model 5113 is a high performance, low noise voltage preamplifier with continuously adjustable gain and selectable high, low or band pass filtering.

Model 5182 Current Preamplifier

Model 5182 Current Preamplifier

The model 5182 is a current-to-voltage preamplifier of low noise and low input impedance designed to amplify the extremely low currents encountered in such areas as photometry and semiconductor research.

Model 5184 Ultra Low Noise Preamplifier

Model 5184 Ultra Low Noise Preamplifier

The model 5184 is a medium input impedance, AC-coupled, voltage preamplifier which features an ultra-low noise input stage. It has a frequency response from 0.5 Hz to 1 MHz and a fixed gain of x1000 (60 dB) and incorporates a special pseudo-differential input stage that can be floated to give the ground loop immunity normally associated with true differential inputs but without the associated noise penalty.

Model 5185 Wideband Preamplifier

Model 5185 Wideband Preamplifier

The model 5185 is a wideband voltage preamplifier with a frequency response from DC to 200 MHz and switchable gain settings of x10 (20 dB) or x100 (40 dB). It has a selectable input impedance of 50Ω or 1 MΩ and a DC offset facility.

It has a frequency response from 0.5 Hz to 1 MHz and three switched gain settings of x10, x100 and x1000. It is a general purpose preamplifier which has the facility to be connected to grounded sources in a manner which breaks ground loops and since it has a true differential input it can be used to measure floating sources, such as the output from an AC bridge, without imposing an asymmetrical load onto the source.

Model 181 Current Preamplifier

The model 181 is a current-to-voltage preamplifier of low noise and low input impedance designed to amplify the extremely low currents encountered in such areas as photometry and semiconductor research.
