Description
Stanford Research SR550 FET Voltage Preamplifier
The SR550 Voltage Preamplifier is designed to work with SRS lock-in amplifiers. Preamplifiers provide gain close to the experimental detector, before the signal-to-noise ratio is permanently degraded by cable capacitance and pickup. The SR550 minimizes noise and pickup in the connecting lines and reduces measurement time in noise-limited experiments. Power and control signals are brought from the lock-in by a 9-pin cable. The SR550 may also be operated independently by applying appropriate biasing (±20 VDC, +5 VDC).
Features:
- 3.6 nV/√Hz Input Noise
- FET Input, 100 MΩ Input Impedance
- Gain of 1, 2, 5 or 10
- Single-ended and Differential Inputs
- AC Coupled Input
- Powered by SRS Lock-in Amplifiers
- High Common Mode Rejection
