Hi all, There are two daughter boards in N310, the phase difference between channels of different dboards will drift rapidly.
In my test, a B200 transmits single tone continuous wave to a 1-to-2 splitter, and the outputs of splitter are connected to input ports of RF0 and RF2 of N310. During the single program running, the signals received by the two channels should keep the phase difference approximately stable. But I observed that the phase drift of the two channels was very fast. Within a time span of 20 seconds, the phase difference varied by tens of degrees. Sense that two dboards are using independent reference clocks, not the same reference clock from mboard. By contrast, the phase difference between the two channels of x310 with two ubx is stable. Does anyone know how to explain this issue? Best regards, Damon
