FREQUENCY REFERENCES

GPS-12R Portable Reference Clock

The Pendulum GPS-12R Portable Reference clock is an ultra-stable GPS-disciplined Rubidium reference, targeted for telecommunications application. Its high stability and low noise output, makes GPS-12R the ideal reference source for telecom instrumentation and testers, like SDH/PDH/Sonet Analyzers. Its Cesium standard performance, when locked to GPS, makes GPS-12R an ideal calibrator for metrology and test systems.

GPS-88/89 Frequency Standard

The GPS-88/89 features the only traceable GPS-controlled frequency standard on the market. GPS-controlled frequency standards are especially suited for use in calibration departments, providing continuous traceability with no need for external calibration. The stability over 24 hours is excellent with one part in a trillion. Unlike other GPS-disciplined oscillators (GPSDO), the disciplining process is not hidden to the user. The incorporated high-resolution phase comparator continuously compares the local oscillator with the GPS transfer standard. The result of that comparison is stored internally and can be transferred on demand to a PC. The frequency offset is displayed on the front panel and the values are stored in NVRAM for a period of at least 2 years.

6688/6689 Frequency Standards

The 6689 with a Rubidium clock and the 6688 with a high-stability oven-controlled crystal oscillator, are designed for use in test systems, where a very high stability frequency reference is required and where multiple instruments or testers need to be supplied. The Frequency References are also suited for calibrating various instrumentation, like frequency counters and synthesizers.
