I changed the frequency of the RX RF PLL, but the waveform of the RX output has not changed. I think the mixer is not working. How do I determine if the mixer is working properly?
What hardware and SW are you using ? Is your TX working ?
Have you tried using Evaluation hardware and Software.?
If using evaluation board, When you change the LO frequency , the center frequency of captured waveform as well changes in IIO. Can you share the plot what you are seeing.?
