T710 GNSS Rubidium Atomic Frequency Standard

T710 Portable High-Precision Frequency Reference

The T710 GNSS Rubidium Atomic Frequency Standard integrates a GNSS receiver, a Rubidium atomic clock, and a low-phase-noise crystal oscillator. Using digital phase-locking technology, it outputs a high-precision 10MHz frequency signal with frequency stability comparable to that of a standard cesium clock. It supports 1PPS and UTC synchronization, features smooth frequency division and anti-interference capabilities, and automatically switches to the Rubidium clock if GNSS lock is lost. Supporting multiple signal outputs, including 10MHz, 1PPS, and Time of Departure (TOD), it is suitable for high-reliability applications such as radar, communications, power generation, and metrology calibration.
