srs SR240A-300 MHz quad preamplifier

主要指标与说明The model SR240A 350 MHz Preamplifier is a 4-channel, DC-coupled instrument with a gain of 5 per channel. The amplifiers can be used independently or cascaded to provide gains of 5, 25, 125 or 625. The fast rise time, low noise, and DC accuracy of the SR240A make it the ideal instrument for use with photomultiplier tubes and photodiodes.Four independent channelsDC to 350 MHz bandwidth1 ns rise and fall timeVoltage gain to 6256.4 nV/√Hz input noise50 Ω input and output impedance3 ns overload recoveryExcellent phase linearity

The fast rise time, low noise, and DC accuracy of the SR240A make it the ideal instrument for use with photomultiplier tubes and photodiodes.The SR240A preamp is useful for amplifying small signals to levels that can be processed by other boxcar system modules. Typically, a signal of at least a few millivolts is required at the input of the SR250. If your detector does not supply this signal level, the SR240A can be used in front of the SR250 to ensure sufficient signal amplitude.SR240A 300 MHz PreamplifierGeneralAmplifier channels 4Inputs & outputs 50 Ω DC coupledBandwidth DC to 350 MHz (-3 dB)Rise/fall time 1 ns (single channel)Voltage gain 5 per channel.
