Abstract

A high-performances 16-channel spectroscopy amplifier having high performances has been developed in a single width NIM unit. The pole zero cancellation, the coarse and fine gain, the shaping time, the output polarity and the output DC offset Can be adjusted through a serial interface. The selected values are stored in a non-volatile memory. Each channel has three analog outputs. The first has a nearly gaussian shape with gain from 0.5 to 256 (2048 possible values), the second is a similar pulse with again 10 times the choosen value of the first output. The last is a fast signal suitable for timing purposes. The module has an additional multiplexed output that can be programmed to present the output of any channel for remote monitoring
