The Mod. V925 is a 1-unit VME module which houses three 4 In / 4 Out and one 3 In / 3 Out sections; one Discriminator channel is also featured.
Each Fan in/Fan out section produces on all its output connectors, the sum of the signals fed to the inputs, eventually inverted.
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.
