N455

Quad Coincidence Logic Unit

Datasheet

Home Modular Pulse Processing ElectronicsDigitalCoincidence/Logic/Trigger Units N455

Photo of N455
  • 4 identical independent sections

  • Two inputs per section

  • 130 MHz Max input frequency

  • 6 ns double pulse resolution

  • 10 ns I/O delay

  • Switch selectable AND/OR logical function

  • Adjustable output FWHM (4 to 650 ns)

  • Overlap output

  • Common Veto

The Mod. N455 houses, in a single width NIM module, 4 independent sections performing the logic function, AND or OR, selected via the relevant front panel switch. Each section has 3 normal and 1 complementary NIM shaped outputs whose width can be set via front panel trimmer and a supplementary overlap output (OVP OUT) whose width is equal to the time interval during which the desired function is satisfied. The OVP OUT allows to obtain an output signal with the minimum input/output delay. A common veto input signal is available to disable all the output signals. (ISN-GRENOBLE design)
