IDQ’s ID801-TDC is an 8-channel time-to-digital converter, coincidence counter and time interval analyzer. This system is used to transfer the time-tags of registered events with picoseconds precision and at high rates to a PC. Additionally, it can count single and multiple channel coincident events at even higher rates internally and convey those to a PC.

New features:

  • Programmable divider: trigger the TDC up to 100MHz
  • Data transfer up to 5 millions events per second
  • NIM – TTL -LVTTL and variable inputs

The ID801-TDC registers incoming signal events on 8 independent channels, records their exact time (bin size 81 ps) and channel number and communicates these to a PC. A graphical user interface is supplied for Windows® and Linux, software examples are available for C/C++ (Windows® and Linux) and Labview™.

The ID801 comes with 4 standard interfaces:

  • GUI Software
  • Command Line Interface
  • LabView Sub VIs
  • C User Libraries
