Faster Noise-Limited Measurements

The SE4002 is a low-noise, ultra-high input impedance preamplifier with excellent common-mode rejection. It is designed to work with any Saluki digital lock-in amplifier. The preamplifier minimizes noise and pickup in the connecting lines and reduces measurement time in noise-limited experiments.
