CNT85/85R Frequency Counters
The CNT85/85R is two high-performance frequency counter models for every need and budget. Choose from the basic 300 MHz frequency counter CNT-85 or the ultimate portable frequency calibrator CNT-85R with built-in Rubidium time base.

Both counters can be equipped with optional HF-inputs to 2.7 GHz and a GPIB-interface, for use in automatic test systems, or in PC-controlled instrument clusters on the lab bench or workshop bench. A new option - the 8 GHz Prescaler input - extends the frequency measuring range.

Easy to Use
The CNT-85 is a compact portable high-performance frequency counter ideal for portable frequency calibration. It is very easy to use, thanks to an advanced and intelligent Auto Set function, which ensures perfect triggering on any type of input signal. Compared with other frequency counters, the CNT-85 has a lot extra to offer, like an input signal level meter (analog bar graph), pulse width and duty cycle measurements.

The CNT-85R is an excellent portable calibrator for calibration of the master clock in GSM base stations. Its built-in atomic clock never needs to be adjusted during the lifetime of the network.
