1. Module description
1.1 Overview
The Mod. N625 is a 1-unit NIM module which houses:
−
Four linear 4 Input + 4 Output Fan in/Fan out sections
−
One 1 Channel Discriminator
Each Fan in/Fan out section produces on all its output connectors, the sum of the signals
fed to the inputs, multiplied for the selected gain factor (1 or –1, jumper selectable).
Gain = 1 (non inverting mode) and gain = -1 (inverting mode) are signalled by LEDs.
Fan in/Fan out inputs are bipolar, both input and output signals are DC coupled.
Moreover each Fan in/Fan out section features a screwdriver trimmer which allows the
DC offset (“zero”) adjustment.
The discriminator channel has one DC coupled input, an internal jumper allows to
perform the slope coupling on either the leading or the trailing edge; the threshold is
screwdriver adjustable and monitorable via test point; the output is NIM standard, its
width is screwdriver adjustable as well.
The discriminator In/Out connectors are placed on the back panel, while its controls are
on the front panel.
