ID900 Time Controller

Time-tagging, delay and pattern generation

  • Timestamping and histogramming
  • Delay generation with multi-hit ability
  • Pattern generation
  • 1 GHz counters

IDQ’s Time Controller is designed for flexibility and it aims to efficiently and reliably solve a large number of problems encountered in the modern laboratory. It performs the funtions of a number of devices: Time-tagger, delay generator, pattern generator, counter and discriminator. Its hardware consists of 4 inputs and 4 outputs that are interconnected internally via a fast FPGA. It offers two modes. The high speed mode allows fast count rates up to 100 Mcps on each channel and a binning of 100 ps while the high resolution mode has a binning of 13 ps and allows a maximum count rate of 25 Mcps on each of the four channels.

The Time Controller is an evolutive device. Extra functionalities can be implemented remotely by updating the firmware and the software
