V974

Overview

The Mod. V974 is a 4 channel fast rise time amplifier housed in a 1-unit VME module; each channel features a voltage gain adjustable from 1 to 10 in x1 steps. Channels are non-inverting and bipolar: they amplify both positive and negative signals. Input bandwidth is 170 MHz for signals up to 50 mVpp and decreases for larger ones (up to 100 MHz @ 400 mVpp). Gain setting is performed independently for each channel via four rotary handles. Channels can be cascaded in order to obtain larger gain values. Each channel is provided with three LEMO 00 connectors, one for the input and two bridged for the output. The board features a ±2 V output dynamics. 4 screw-trimmers (one per channel) allow the offset calibration which operates over a ±25 mV range. The features include an output short circuit protection.
