Product Details

Overview

Signal Recovery originated from the Princeton Applied Research, EG&G products for scientific instrumentation. They are the inventors of the lock-in amplifier. A lock-in amplifier is an instrument with dual capability. It can recover signals in the presence of an overwhelming noise background or, alternatively, it can provide high resolution measurements of relatively clean signals over several orders of magnitude and frequency.

Highlights

Remote control via software only (no built-in display)
Dual reference and dual harmonic detection allow signals at two different frequencies to be measured simultaneously
Frequency range 250 kHz to 1 mHz
Ethernet, USB, RS232 connectivity
Compact design has no mechanical fans and is completely silent, especially useful for acoustic research
Software included - Acquire PC software, browser control software, LabView and SRInstComms
