FET input preamplifier The Stanford Research SR550 Voltage Preamplifier is designed to work with any SRS lock-in amplifier. Preamplifiers provide gain close to the experimental detector, before the signal-to-noise ratio is permanently degraded by cable capacitance and pickup. The preamplifier minimizes noise and pickup in the connecting lines and reduces measurement time in noise-limited experiments. SRS SR550 Features FET input, 100 MΩ input impedance Gain of 1, 2, 5 or 10 3.6 nV/√Hz input noise Single-ended and differential inputs AC coupled input Powered by SRS lock-in amplifiers High common mode rejection Ask for SRS SR550 detailed specification.
