AD9371 configuration RX channel gain, MGC mode, configuration 195~210 is correct, but there is a problem in the upward configuration, the spectrum is completely wrong.Currently, there are only one good point for the 10 boards, and the other nine are basically a phenomenon.That piece is good between 210 and 255, but there are a few values that don't work.
This is the configuration of 220, all three exceptions.The anomalies are not the same.
When normal, it is normal to change the size of input signal, and the amplitude is normal.So it's not a problem of saturation overflow.I just changed the RX gain configuration, just a number, 0.5dB change.Please reply as soon as possible. Thank you.
