Dear Nur Qalbi,
There's two issues that I'd like to address separately:
1. RF LO warning
2. Sampling rate warning.
1. Shouldn't really be a warning, because, as the output says, in the end
tuning is successful. The reason you're seeing this is UHD being a little
verbose about how it tuned. Don't worry, things should work as expected.
2. Is much much more severe: you seem to have modified the flow graph to run at
5GS/s. That does neither technologically, physically nor mathematically make
much sense - did you perhaps intend to tune to 5GHz RF frequency?
Best regards,
Marcus
