The field trial of the frequency dissemination system for Square Kilometre Array radio telescope

Abstract

To satisfy the Square Kilometre Array's (SKA) frequency dissemination requirement, Tsinghua University designed a “1f-2f” frequency dissemination system. Compared to the former frequency dissemination system, it has better expandability which can support the star topology frequency dissemination network. In order to get the specifications as well as to find the potential problems of the frequency dissemination system for the SKA radio telescope, a field test was carried out at South Africa SKA site from 19/09/2015 to 27/09/2015. During these days, four tests were performed. From the field test results, we conclude that Tsinghua's Frequency Transfer System is capable for operated on the overhead fiber link, as well as long distance dissemination requirement.
