CNT-91R/AF/20
Frequency Reference/Calibrator/Analyzer

Overview
CNT-91R/AF Frequency Calibrator/Analyzer & Frequency Reference
The Pendulum CNT-91R/AF Frequency Reference/Calibrator/Analyzer features a combination of a multi-output Rubidium Frequency Reference and a high resolution Frequency Counter/Analyzer, creating a dynamic measurement, analysis, and calibration system. Supply an ultra-stable reference frequency of 0.1, 1, 5, and/or 10 MHz to any test instrument, and calibrate any frequency source to 3 or 20 GHz. The CNT-91R/AF is a unique all-in-one frequency reference/ counter/analyzer/calibrator, with no competing product on the market.
