Pitor: We've seen a similar issue and have worked around it by just using a slightly different frequency. Can you post the frequencies that you're seeing it on? I think Ettus should be able to duplicate. I saw an issue with spectral inversion (I think I and Q are getting swapped somewhere) at 2

I’m working with the TwinRX and am having the same results as Emanuel. I was ignoring the warning about the sample rate but you said that it must run at 200MHz. Can you explain why UHD sets the sample rate to 100MHz if 200 is required? Thanks, -Kevin On Mon, 14 Jan 2019 at 7:06 AM Emanuel vi

[USRP-users] X300 MIG

2017-12-11 Thread Rigney, Kevin E via USRP-users
Hello, I'm looking to build a custom design using the DRAM on the X300. There are some custom changes Ettus has made to the MIG and I'd like a little clarification. What's the difference between ui_clk and ui_clk_x2? What clock rate is the ui_clk running at? What clock should I use if I want to
