Four independent sections
Bipolar inputs
Four 4 Input + 4 Output Fan in/Fan out sections
1 Channel Discriminator featured
Inverting or non-inverting mode independently selectable on each section
100 MHz bandwidth
The Mod. N625 is a 1-unit NIM module which houses four 4 Input + 4 Output Fan in/Fan out sections and a Single Channel Discriminator.
Each Fan in/Fan out section produces on all its output connectors, the sum of the signals fed to the inputs. Fan in/Fan out inputs are bipolar, while the output can be either inverting or non inverting (jumper selectable independently for each section). Both input and output signals are DC coupled. Maximum input amplitude is ±1.6 V. Moreover each Fan in/Fan out section features a screwdriver trimmer which allows the DC offset adjustment. The discriminator channel has one DC coupled input (polarity is jumper selectable), the threshold is screwdriver adjustable and monitorable via test point; the output is NIM standard, its width is screwdriver adjustable as well. Front panel LEDs allow to monitor all the mode, gain and polarity adjustments performed via internal jumpers.
