Product Description
The T760 GNSS Disciplined Rubidium Atomic Frequency Standard Server consists of a high-precision timing GNSS receiver, high-performance rubidium atomic clock, low-phase-noise phase-locked crystal oscillator, control module, and low-noise amplifier module.
By utilizing digital phase-locking technology, it combines the long-term stability of GNSS, low aging characteristics of rubidium atomic clocks, and the high short-term stability and low phase noise of temperature-controlled crystal oscillators. This innovative design results in a low-phase-noise high-precision atomic frequency standard with both long-term and short-term stability, providing high accuracy.
When in GPS lock state, the stability of the 10MHz frequency can reach the performance of a regular cesium clock, offering excellent cost-effectiveness.
The T760 GNSS Disciplined Rubidium Atomic Frequency Standard equipment is designed in a 2U chassis and can output 10MHz, 1PPS, IRIG-B, NTP, and TOD information (optionally supporting multi-channel 100MHz, 80MHz, 5MHz, and 1MHz outputs). It can be widely used in radar, communication, metrology calibration, power, electronic warfare, space measurement, and control fields.

Unified Network Monitoring Software:
BDMonitor is a unified network time monitoring software that can monitor satellite information, server information, and client information. Satellite information includes satellite time, lock status, number of locks, latitude, longitude, altitude, and other details. Server information includes NTP time synchronization status, synchronization status, server time, network configuration, and more. The monitoring and alarm information supports protocols like syslog and email or stores events in local logs. It supports monitoring of at least 10,000 clients and allows configuration of alarm types and levels for selective reporting. The software provides direct querying and configuration of network parameters and offers rubidium clock disciplining/maintenance, loss of lock/gain of lock status (remote) monitoring functions.
