– 8 stop channels at a time bin resolution of 82 ps, measurement range 0 ns - 10.6 µs in start-stop operation (double TDC option: 16 stop channels, 1 or 2 start channels)
– 2 stop channels at a time bin resolution of 27 ps, measurement range 0 ns - 40 µs in start-stop operation (double TDC option: 4 stop channels, common start input)
– measurement range extendable on request
– min. time between start and stop 0 ns, pulse pair resolution 5.5 ns, min. 32 hits / channel
– multi-hit capability extendable by FPGA options (e.g. hit tagging, see PLU-option)
– no minimum time limit for hits at different channels
– transfer rate up to 8 million results per second via USB 2.0 readout (interface available for Windows® 2000, Windows® XP, Windows® Vista and Windows® 7 32 bit operating systems)
– LabVIEW VI interface
– DLL for user programming

 Available option:
PLU-Option (FPGA preconditioning feature), enables extended functionality, e.g.:
