Pendulum Instruments introduces CNT-91R, a compact high-performance frequency calibrator/analyzer

Pendulum Instruments introduces CNT-91R, a compact high-performance frequency calibrator/analyzer


Pendulum Instruments, a company of the Orolia Group, announces the introduction of CNT-91R, 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.

Main product features and benefits are:

  • Calibration/Analysis of the highest precision OCXOs
  • Ageing per month is <5*10-11
  • Short warm-up time, only 12 minutes to reach 5*10-10
  • Frequency resolution is 12 digits in one second measurements
  • Graphic display shows numerical statistics data, histograms or trends (frequency vs. time)
  • Compact "one-box-solution" for portable frequency calibration and analysis
