With the CNT-85 and CNT-85R frequency counters and calibrators, Pendulum offers the ultimate tools for stationary as well as portable calibration of frequency, from DC to over 8 GHz. These counters are designed for on-site calibration of the master clock in GSM base stations, offering a TUR of >50 over a 10 year period. They also fit on the R&D bench, in the calibration lab or in manufacturing test systems where fast and accurate frequency measurements are needed. Choose between the economy model CNT-85 and the ultimate CNT-85R including a built-in Rubidium time-base reference.

The CNT-85R from Pendulum is the most accurate portable frequency calibrator on the market. 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-85R is instantly ready for use after a change of location.
