The Aim of the Device

• Need of a RPC simulator providing RPC-like pulses
  for Electronics testing and Crosstalk studies
  with the RPC detector.
• Real detector simulator giving pulses with
  different heights and distribution in time.
• Small size and simple electronic device.
• Lower price than other pulse generators.

What does the Pulser give us?

• Four different output RPC-like pulses
• Negative or Positive.
• Different heights.
• Variable distribution in time width.
• Pulse characteristics
• Minimum time interval of 5ns.
• Minimun width of 1ns.
• Minimun rise time of 600ps.
• Amplitude range from 0 to 2V.

Summary

• A device producing RPC-like pulses is under
  development.
• It will generate up to four parallel narrow and
  high frecuency variable pulses.
• Total power dissipation of 10W.
• It will be very useful for FEE electronics
  testing and crosstalk studies.
• First prototype will be ready in some weeks.
