The Model N979B is a 16 channel fast rise time amplifier housed in a 1-unit NIM module; N979B channels are divided into 4 groups with different fixed gain: x2, x4, x8, x10.
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.
