Question about phase synchronization with X310 and two UBX 40

2019-12-02 Thread Masatetsu Wake
Hello all, My customer is using X310 with two UBX 40 daugther boards and would like to know how he can synchronize the phase. Below is the some of the steps he is trying: 1. I add "dboard_clock_rate=20e6" to the "device arguments" field of the property for the UHD Source block, as the following U
