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/vHz 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
