Products description

T710-H GPS Rubidium Atomic Clock with Temperature-Controlled Crystal Oscillator Frequency Standard is composed 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 integrating the long-term stability of GPS, low aging characteristics of the rubidium atomic clock, and the high short-term stability and low phase noise of the temperature-controlled crystal oscillator using digital phase-locked loop technology, it creates a low-phase-noise, high-precision atomic frequency standard with both long-term and short-term stability and high accuracy, offering a cost-effective solution.

The T710-H GPS Rubidium Atomic Clock with Temperature-Controlled Crystal Oscillator Frequency Standard outputs a 1PPS (One Pulse Per Second) signal derived from the frequency signal of the rubidium atomic clock and synchronized with the UTC (Coordinated Universal Time) provided by GPS. The frequency-divided pulse is smoothed compared to the original pulse, overcoming the influence of pulse fluctuations and jumps, and serves as the replication of UTC time reference. When the GPS signal is lost or abnormal, the device intelligently switches to the rubidium atomic clock timing mode, continuously providing a highly stable time-frequency signal.

The T710-H device is designed in a 3U 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, aerospace telemetry and control, and other fields.
