Overview
Pendulum brand frequency standards offer extreme accuracy for applications in telecommunications, calibration laboratories, automated test systems and design departments.
GPS-disciplined references offer traceable Cesium-like stability at an attractive price. Units are self-calibrating. A stand-alone high stability frequency standard is 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
- Traceable self-calibrating Frequency Standard. No need to send away for external calibration. Save time and money. (GPS-88/89)
- Bring near-Cesium stability to the field with no warm-up time. No need for hours of waiting time. (GPS-12R/12RG plus internal battery)
- Easy-to-use, and operate. No configuration via PC needed
