T760 GNSS Rubidium Atomic Time and Frequency Standard
Learn about our T760 GNSS Rubidium Atomic Time and Frequency Standardrd
The T760 is a high-precision GNSS disciplined rubidium atomic frequency standard. It integrates GNSS, a rubidium clock, and a low-phase-noise crystal oscillator, achieving output frequency stability comparable to that of a cesium clock. It supports 1PPS and UTC synchronization and features automatic timekeeping, frequency smoothing, anti-interference, and encryption. It runs a built-in Linux system and is compatible with PTPv2.1, NTP, and SNTP protocols, achieving nanosecond-level network timing accuracy. Housed in a 2U chassis, it supports multiple signal outputs, including 10MHz, 1PPS, IRIG-B, and Time of Departure (TOD).
