srs SR445A-Quad 350 MHz preamplifier


主要指標(biāo)與說明The Model SR445A 350 MHz Preamplifier contains four wide-bandwidth, DC-coupled amplifiers, each with a gain of 5. The four channels may be used independently, or cascaded to provide a total gain of up to 625. The fast rise time, low noise, and excellent DC accuracy of the SR445A make it an ideal instrument for amplifying the outputs of fast photomultiplier tubes and photodiodes.

The four channels may be used independently, or cascaded to provide a total gain of up to 625. The fast rise time, low noise, and excellent DC accuracy of the SR445A make it an ideal instrument for amplifying the outputs of fast photomultiplier tubes and photodiodes. The SR445A can be used to improve the sensitivity of oscilloscopes, photon counters, boxcar averagers, spectrum analyzers, and other high-frequency test equipment. Each channel has an input and output impedance of 50 Ω. The input impedance of channel 1 can be increased to approximay 500 Ω by a front-panel switch. This can improve the sensitivity of signals from current and charge output devices, such as photomultiplier tubes. Each channel has a separate offset adjustment allowing you to quickly null DC errors.SR445A 350 MHz PreamplifierGeneralAmplifier channels 4Inputs and outputs 50 Ω (DC coupled)Bandwidth DC to 350 MHz (-3 dB)Rise/fall time 1 ns (single channel)Voltage gain 5 per channel (up to 4 channels can be cascaded)Input noise 6.4 nV/√HzOperating range Inputs: ±200 mV, Outputs: ±1.0 VPropagation delay 2.7 ns per channelRecovery time 3 ns for a 10× overloadInput protection ±50 V for<1 msOutput clamp ±1.6 VOutput overload detect ±1.3 VCrosstalk -60 dBOperating temperature 0 °C to 40 °C, non-condensingDimensions 8.3" × 1.5" × 8.0" (WHL)Power 10 W, 100/120/220/240 VAC, 50/60 HzWarranty One year parts and labor on defects in materials and workmanship
