Hi Michael
thanks a lot for the quick reply.
sorry for the unclear description, let me clarify that.
We want to do a sample data transport test thro loopback test between TX and RX part based on IIO.
we try to send out the baseband signal (sine waveform) on TX, and want to see the sine wave data in RX buffer.
per you point before, we don't employ IQ modulator in baseband part, and just do the up-convert (freq-move) to carry freq 2.4GHz.
And then we could see the carry in RX part thro IIO capture window.
We try to get/save the baseband signal/data after down-convert and FFT operation.
BTW, there is no digital demodulor used also.
So, my question is whether our method is the right way or not? is there missing something?
thanks anyway.
