Stanford Research SR560 Low-Noise Voltage Preamplifier

The SR560 is a high-performance, low-noise preamplifier that is ideal for a wide range of applications including low temperature measurements, optical detection, and audio engineering.

The SR560 has a differential front-end with 4 nV/√Hz input noise and an input impedance of 100 MΩ. Complete noise figure contours are shown in the SR560 Tech Note at the end of this section. The SR560's inputs are fully floating (BNC shields are not connected to chassis ground). Both the amplifier ground and the chassis ground are available on the rear panel for flexibility in grounding the instrument. Input offset nulling is accomplished by a front-panel potentiometer, accessible with a small screwdriver.

  • 4 nV/√Hz input noise
  • 1 MHz bandwidth
  • Variable gain from 1 to 50,000
  • AC or DC coupled
  • Two configurable signal filters
  • Differential and single-ended inputs
  • Line or battery operation
  • RS-232 interface
