Overview

Pendulum brand frequency references offer extreme accuracy for applications in telecommunications, calibration laboratories, automated test systems and design departments.

GNSS-disciplined references offer traceable Cesium-like stability at an attractive price. Units are self-calibrating.

Two stand-alone high stability frequency references are available where traceability to external reference is not required.

Benefits

• Get the accuracy and stability of a Cesium clock at a fraction of the cost (FTR-210R).
• Traceable self-calibrating Frequency Standard. No need to send away for external calibration. Save time and money. (FTR-210R).
• An optional measurement input converts the reference to a complete one-box ultra-high performance frequency & time calibrator. No need to carry multiple instruments for a field calibration (FTR-210R).
• Easy-to-use, and operate. No configuration via PC needed.
