The Mod. N968 is a spectroscopy amplifier implemented in a single-width NIM module. It accepts the typical outputs generated from either optical response or resistor response preamplifiers connected with nuclear particle detectors.
A front panel switch allows to select between positive and negative input signals.
Gain setting can be performed continuously in the 10 ÷ 1500 range, product of Coarse, Fine and Superfine Gain. Two internal jumpers allow to set a x0.1 attenuation and a further x2 amplification, thus extending the gain range to 1 ÷ 3000.
Shaping time (Ts) values are 0.5, 1, 2, 3, 6, 10 μs.
The Pole Zero (PZ) cancellation is performed via a front panel screw-trimmer. The module features also:
-a Bipolar output (to be used for timing purposes)
-An advanced Baseline Restorer (BLR) circuit, with either manual or automatic threshold setting
-A Pile Up Rejector (PUR) which allows to reject piled up events
