Time Measurement

Image of time to digital converter clock source cronologic offers a diverse portfolio of time measurement solutions:

Dedicated time-to-digital converters (TDC) with ultra high single shot resolution down to 13ps, as well, as high speed flash ADC boards with hardware preprocessing for pulse signals are available.

A low cost series of time taggers is available for applications that do not require ultra precise single shot timing resolution.

All product lines can be used as frequency counters, time interval analyzers (TIA) and for single photon counting.
