This is done inPreface1-2 IntroductionPrefacetwo identical circuits by charging an integratingcapacitor with a constant current, starting at thetrigger event. Charging is stopped at the leadingedgeof thefirst followingclockpulse.

The SecureSync platform is the successor product. The successor product is VersaSync rugged time and frequency reference. An overfl ow mode displays also the 11th and 12th digits, when needed. The CNT - 85 is easy to use, compact and has a unique, smart automatic input triggering for any type of signal. A very short warm-up time of the oven oscillator, gives you ppb-performance after only 10 minutes. It offers all the functionality of the CNT - 85, plus the stability and accuracy of a built-in Rubidium atomic reference. This instrument is ideal for high-accuracy frequency calibration, inside as well as outside the cal lab environment, such as in digital communication systems. The short warm-up time means that the CNT - 85 R is instantly ready for use after a change of location.
