Time interval and frequency standard Pendulum Instruments
Time interval and frequency standard products developed by Pendulum Instrument is based with model 6688 and model 6689. But also, time GPS-controlled interval and frequency standard. Those products are based on a Rubidium reference (GPS-89) or an oven-controlled crystal oscillator.
- 6688 & 6689 : Achieve a stable frequency reference in calibration labs or test systems with the stand-alone high stability oven-controlled crystal oscillator found in the 6688 Frequency Standard. For greater stability employ the Rubidium Frequency Standard 6689, ensuring frequency drift due to aging of less than 0.001ppm per 10 year period.
- GPS-12R : A portable reference standard for ultra-stable GPS-controlled Rubidium reference with near-Cesium accuracy; the GPS-12R is the recognized measurement device for telecom and wireless communication field applications where battery operation with zero warm up after transportation, and hold-over drift rate of less than 1microsecond after 24 hours for uninterrupted operation is required. As a NIST traceable frequency standard, the GPS-12R is ideally suited as the in-house frequency standard for all test equipment.
