T770 Metrology-Grade Atomic Frequency Standard
Enhanced Grandmaster Clock (ePRTC)
The T770 is a metrology-grade rubidium atomic frequency standard, offering frequency stability, drift, and temperature coefficient up to 10 times better than ordinary rubidium clocks, and a one-day frequency stability comparable to that of a small cesium clock. It supports 1PPS and GNSS UTC synchronization, uses smooth frequency division to ensure a stable time base, and automatically maintains time in the event of a loss of lock. It features anti-interference algorithms and outputs multiple signals, including 10MHz, 5MHz, 1PPS, and Time of Departure (TOD). Options include 100MHz, 90MHz, and IRIG-B. Its 2U chassis makes it suitable for applications such as ePRTC master clocks, radar, communications, metrology, and aerospace measurement and control.
