Dear fellow users, I intend to put together a 8 channel data collection system using 2 X310s, each mounted with 2 TwinRXs. With the guidance from the past experience in this forum, I have installed the hardware and started data collection on a computer running on Ubuntu 16.04 LTS and UHD 22.214.171.124. Time and frequency synchronisation were obtained by using the clock and PPS from external Octoclock-G, and also timed command for the two X310s as source0 and source1.
However, I realised that as the TwinRXs in different X310s did not share LOs, the data collected was not phase synchronised. I am currently trying to take LO1 and LO2 from one of the boxes and sharing it with the other TwinRXs via an RF splitter. The first TwinRX LOs are set to "Internal, True (for export)" and "Companion, True", while the rest are set to "External, False". I shall refer to the former TwinRX as "Master", and the remaining as "Slave". The Master is in RX A slot of the first X310. With this setup, I am able to achieve phase synchronisation repeatedly for the Master, and Slaves placed in RX B slot of X310. The Slave place in RX A slot of the second X310 has a phase which starts independently of the Master. Any kind advice of what I am missing to achieve phase synchronisation of the last Slave? Regards, GOH Liang Zhen
