Product Description:
The SR550 voltage preamplifier is designed to work with any SRS phase-locked amplifier. The preamplifier provides gain close to the experimental detector, and then the signal-to-noise ratio is permanently reduced due to cable capacitance and pickup. The preamplifier minimizes noise and pickup in the connection line and reduces measurement time in noise-limited experiments.
Features:
3.6 nV/√Hz Input noise
FET input, 100 MΩ input impedance
The gain is 1, 2, 5, or 10
Single-ended and differential inputs
Ac coupled input
Powered by SRS phase-locked amplifier
High common mode rejection
