PCI TIC
The TIC is a time interval counter module for PCI computers. It offers 40-bit counters. You can perform a wide variety of counter tasks with the TIC, including event counting, period measurement, pulse width measurement, frequency measurement, etc.

The TIC uses reciprocal counting techniques to achieve high-resolution measurements on lower frequency signals without sacrificing measurement time. Reciprocal counting provides a fixed number of digits of resolution for all frequencies rather than a fixed resolution in Hz for the same gate time.
