The time interval counter NSZ was developed by K+K to calculate the time difference between two input signals. K+K DNSZ is the expanded cascadable version allowing measurement of several input signals in comparison with a common time reference. Up to 8 different signals are possible, the achieved resolution for the time differences is 50 ps.
The devices are offered as single version (19" plug-in module) for special measurement applications (for example delay measurements) and as a complete system K+K ZFM.
K+K ZFM integrates more than one K+K DNSZ, optionally the corresponding number of K+K FXE channels and a controlling and protocolling unit. It can be used as time and frequency monitor for clock generators (typ. 1PPS / 10MHz).
