Product Description:
The T710-GROH GPS Rubidium Atomic Clock with Temperature-Controlled Crystal Oscillator (TCXO) Frequency Standard consists of a high-precision timing GPS receiver, high-performance rubidium atomic clock, low-phase noise phase-locked crystal oscillator, control module, and low-noise amplifier module. By combining the long-term stability of GPS, low aging characteristics of rubidium atomic clocks, and the high short-term stability and low-phase noise features of the temperature-controlled crystal oscillator through digital phase-locked loop technology, it innovatively creates a low-phase noise, high-precision atomic frequency standard with excellent short-term and long-term stability and high accuracy. In GPS lock mode, the 10MHz frequency stability can reach the performance of ordinary cesium clocks, providing a cost-effective solution.
The T710-GROH GPS Rubidium Atomic Clock with TCXO Frequency Standard outputs a 1PPS signal derived from the frequency signal of the rubidium atomic clock, synchronized with the UTC time output by GPS. Compared to the original second pulse of GPS, the divided pulse is smoothed, overcoming the impact of original pulse fluctuations and jumps, and reproducing the UTC time reference. When the GPS signal is lost or abnormal, the device can intelligently identify and automatically switch to the rubidium atomic clock timing mode, providing a continuous high-stability time and frequency signal.
The T710-GROH is designed in a 2U chassis and can output 10MHz, 1PPS, and TOD (Time of Day) information (optional support for multiple 10MHz, 5MHz, 1MHz, 1PPS outputs). It can be widely used in radar, communication, metrology calibration, power, electronic warfare, space telemetry and control, and other fields.
