The full specification of T4100U Counter is available in the PDF file.
The advanced Time/Frequency Counter T4100U is contained in a small, light, and handy case connected by two USB 2.0 ports to computer (notebook, netbook, or PC). It combines a 10 ps precision (RMS) of single-shot time-interval 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. Extended built-in memory of measurement results (model with external power supplier) helps designing complex measurement sessions.
The heart of the instrument is a newly developed counter chip, which contains an interpolation time counter with two precise two-stage Time-to-Digital Converters and a built-in microcontroller. The on-board data memory allows for a high measurement rate. The counter T4100U contains a Temperature- Compensated Crystal Oscillator (TCXO) which provides high accuracy at reasonable cost. An external reference clock, e.g. atomic standard, can also be used.
