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.
