Hi Larry, I don't have experience with the N310 but I have used the X310 with a TwinRx card. I had a Gnuradio flow setup to capture both channels into files. 10Gbit network. Executing the Python script from Gnuradio resulted in captures being stored as two INT16 IQ files. When I looked at

Hi Larry, Which carrier frequency do you use for your tests? Something like 2.4GHz? do the 4 receive channels have a stable phase between them? i.e. if you don't move the transmit antenna or your RX array, the phases do not change? I assume you have 1 TX antenna and 4 RX antennas. I would

Hello everyone, I am having an issue with achieving a phase-synchronous RF configuration using an N310 with an Octoclock and a linear antenna array. What I believe should be the expected results of this setup is that each AD9371 should receive synchronous signals aligned in phase, with a
