Hey Marcus Okay, we looked into this and realized that the rx_samples_to_file program has a bug. When you set the channel, it doesnt tune the center frequency of the desired channel which is why the amplitudes are off. Anything other than the first channel is at DC. Finding this bug led me to a

Hello all I noticed in my testing that I am seeing significant mismatch in amplitude on each channel of my N200(lfrx db) with the second channel being much weaker. I thought that it was a problem with my code, but when I hook up a signal generator and split to both RX ports and use the
