The MCS-CT3 counter timer module is suitable for counting all sources of TTL pulses especially from the ET Enterprises AD8 amplifier/discriminator. 

  • 150 MHz capability
  • USB 2.0 interface
  • channel widths from 200us to 999hr
  • trigger input for synchronous counting
  • software can be customised by user
  • labVIEW virtual instrument software included

Operation

The following operating modes are available with the software application provided:

  • continuous readings
  • fixed number of readings
  • fixed run-time
  • simultaneous operation of two counters
  • automatic plateau plots (when using HV control interface)
  • external trigger option to start and stop measurements

Software and User Manual

The MCS-CT3 combines two indepenent software applications both of which have sufficient functionality to enable operation as a self-contained counter timer, or a photon counting system when combined with an ET Enterprises AD8 amplifier/discriminator and detector.

Cables

A USB cable is included, which caries the data from the MCS-CT3 and provides power.

A cable LEADAD8MCS-CT3 is available to provide power for an AD8 amplifier/discriminator.

TTL input is via a BNC connector
