LED Pulsers for MULAN


The LED flasher system.


Three main components:

  1. Flight simulator (FS)
  2. LED flasher boards
  3. Driver boxes.


The flight simulators are 9U VME modules that provide ecl triggers to the system via 34 pin twisted pair cables.  Each 34 pin ribbon cable plugs into the back of the LED driver box and provides the triggers (one for each LED).


Cabling DETAIL for the FS.


A clock signal is required to drive the outputs. The experimental clock is fed to a divide clock box and set so that the frequency that the FS receives is less than 30 MHz. The flight simulator needs to keep the separation between pulses on the same channel to greater than 10 usec.
