NEW FOCUS 2011 200-KHZ FRONT-END PHOTORECEIVER
It features features low-noise detectors, variable-gain transimpedance amplifiers, and two adjustable filters. The DC 30 setting prevents your signal from going off-scale due to DC amplitude fluctuations, without attenuating fast signals. The high-pass filter can be adjusted to eliminate residual 60-Hz noise, and the independent low-pass filter can be set to dampen noisy signals. Variable gain of up to 90 dB in 10-dB steps gives you a useful input range from 1 pW to 10 mW.
