CNT-81 Timer/Counter/Analyzer

Pendulum Instruments offers a choice of two high-performance timer/counter models; the fast/high-resolution CNT-81 and the CNT-81R with built-in Rubidium time base, which allows frequency calibration of the highest possible specified oven oscillators. The counters are equipped with GPIB-interface as standard, for use in automatic test systems, or in PC-controlled instrument clusters on the lab bench or workshop bench. The standard frequency range of 225/300 MHz can be extended to 2.7 GHz. With the new 8 GHz prescaler input option, the frequency measuring range is extended into 8 GHz. Optional timebase oscillators extend the timebase stability to 0.02 ppm/year. The CNT-81R has a built-in atomic clock standard (Rubidium).
