Overview
The Model N979 is a 16 channel fast rise time amplifier housed in a 1-unit NIM module; each channel features a fixed voltage gain of 10; fixed gain values in the x2 ÷ x9 range (gain step = 1) are available on request.
Channels are bipolar, non-inverting. Channels can be cascaded in order to obtain larger gain values. Input bandwitdth is 250 MHz for signals up to 50 mVpp and decreases for larger ones (up to 130 MHz @ 300 mVpp).
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. 16 screw-trimmers (one per channel) allow the offset calibration which operates over a ±30 mV range. The features include an input overvoltage protection.
