Calibrated Stanford Research SR560 Low Noise Preamplifier. High-performance, low-noise Preamp
Low Noise Preamplifier The SR560 is a high-performance, low-noise preamplifier that is ideal for a wide variety of applications including low-temperature measurements, optical detection, and audio engineering.InputsThe SR560 has a differential front end with 4 nV/?Hz input noise and an input impedance of 100 M?. Complete noise figure contours are shown in the graphs below. 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.In addition to the signal inputs, a rear-panel TTL blanking input lets you quickly turn off and on the instrument's gain. This is useful in preventing front-end overloading. The gain turns off 5 Micros after the TTL level goes high, and back on again within 10 Micros after the TTL signal goes low.click to enlargePreamplifier Block DiagramOutputsTwo insulated output BNC connectors provide 600 ? and 50 ? outputs. Both are capable of driving 10 Vpp into their respective loads. Two rear-panel power supply outputs provide up to 200 mA of +/-12 VDC referenced to the amplifier ground. The outputs provide clean DC power for use as a bias source.GainGains are selectable from 1 to 50,000 in a 1- Refurbished
