The full specification of T3100 Counter is available in the PDF file
The heart of the instrument is a newly developed FPGA counter device, which contains a complete interpolation time counter with two precision two-stage Time-to-Digital Converters, a FIFO memory which allows for very high measurement rate, and a dedicated microcontroller. The counter T3100 has on-board a Temperature-Compensated Crystal Oscillator (TCXO), while the model T3100S contains an Oven-Controlled Crystal Oscillator (OCXO) which provides still high accuracy and stability at reasonable cost.
The T3100(S) Time/Frequency Counter occupies a single PCI slot in a PC and combines the picosecond precision of measurement with affordable cost and reliability for thorough industrial and scientific applications. The supplied software creates a user-friendly graphic interface and provides many useful functions for accurate control, diagnostics and statistical processing of the measurement data.
