The Mod. N405 is a one unit wide NIM module housing three independent sections that can be used either as logic unit or majority. The two modes are selectable via internal DIP switches.
Each section accepts 4 input signals, a VETO input and provides 4 outputs (2 normal and 1 complementary, shaped, plus 1 linear). The linear output provides a signal whose width is equal to the time during which the input signals satisfy the conditions programmed via the front panel lever switches. The shaped output widths can be set via front panel trimmers in the range 6 ns to 800 ns.
LOGIC UNIT MODE
The input signals can be disabled by means of a front panel lever switch. Each section can be programmed to perform either the AND or the OR functions via front panel switches. When only one input signal is enabled the section acts as a logic FAN-OUT independently from the selected mode.
MAJORITY MODE
The front panel enable/disable lever switches are used to set the majority level. The AND/OR lever switch must be set in the AND position.
