GPS-Controlled Rubidium Frequency Standard 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.

Portable Frequency Standard 7370

The 7370 is a cost effective and fully portable GPS Synchronised Frequency Standard, which will continue to operate for up to 8 hours without the connection of its GPS and power.

The instrument has fully automatic battery recharging and oscillator calibration overnight, using optional fixed antenna, or while travelling (via in-car charger lead and magnetic base GPS antenna).

GPS Precision Time & Frequency Standard 1804

The 1804 is a Precision Time and Frequency reference using signals from the GPS satellite constellation. Applications include digital audio and TV transmitters, cellular communications. satellite ground stations, calibration laboratories and any application where accuracy and continuous availability are critical.

GPS Master Clock 2804

The 2804 is a Precision Time and Frequency reference using the GPS satellite signals to discipline a high-stability, low-noise oscillator. Applications include DAB and DVB-T transmitters, cellular communications, satellite ground stations, cal. labs and any application where accuracy and continuous availability are critical.

Tracking Oscillator TO-16

The TO-16 is a Precision Tracking Oscillator for 5 or 10 MHz scientific or metrology applications. The TO-16 accepts any noisy frequency input coming from e.g. Rubidium Frequency Standards or badly disciplined GPS-controlled oscillators and effectively remove the noise, while maintaining excellent long-term stability.

GPS-Controlled Frequency Standard for Nordic Countries GPS-88 & GPS-89

Deliver precision frequency and time reference with these GPS-controlled frequency standards. The GPS- 88 and GPS-89 are fully traceable and extremely accurate frequency standards, with applications in telecommunications, calibration laboratories, automated test systems and design departments.

Long-term frequency stability is provided from the built-in Cesium-controlled standards in the GPS-satellite. Very high short-term stability comes from the built-in oven controlled crystal oscillator found in the GPS-88; or the built-in Rubidium atomic clock installed in GPS-89, as its local oscillator.

Frequency References 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.

PicoReference

The GPS PicoReference™ is a low-cost, high-performance frequency reference and measurement test set. It integrates a smart GPS and a Rubidium reference, features a flexible 1-30MHz frequency testing range and a cutting-edge 1 ps measurement resolution. It’s ideally designed for clock characterization and calibration applications.
