Pendulum Instruments CNT-91R High Performance Frequency Calibrators
The CNT-91R is an all-inclusive high performance calibrator of frequency sources, that combines high resolution measurements and advanced analysis, and a built-in ultra-stable Rubidium atomic reference clock. Its compact format, and its short warm-up time make the CNT-91R an ideal transportable frequency calibrator/analyzer. The graphic LCD gives on-screen statistical parameters like mean frequency value, Standard and/or Allan Deviation of frequency, plus unique graphic analysis like viewing initial frequency drift vs. time. The combination of ultra-high stability and resolution enables very fast and accurate frequency calibration. Frequency measurements are made back-to-back, with zero dead-time to enable correct calculation of Allan Deviation.
Transportability: The CNT-91R is an all-inclusive high performance calibrator of frequency sources, including also the highest precision OCXO:s. The compact format, and the short warm-up time, makes the CNT-91R an ideal transportable frequency calibrator
Complete Frequency Calibrator: The following parameters are displayed at a glance on the graphic LCD: – statistical mean value of frequency – Standard and/or Allan Deviation of frequency – Graphic view of initial frequency drift vs time
Fast and Precise Calibration of Mean Frequency and Allan Deviation (ADEV): The combination of ultra-high stability time-base and resolution enables very fast and accurate frequency calibration. Frequency measurements are made back-to-back with zerodead-time to enable correct calculation of Allan Deviation
Oscillator Analysis
The CNT-91R features true zero-dead-time measurements of frequency and phase (TIE), and can therefore be used for wander and jitter analysis of clocks under test.Zero-dead-time measurements are also a pre-requisite for correct calculation of short term stability expressed as Allan Deviation.
