Hi, My ADI Friend:
I have a question about the relationship & sequence of the RX QEC & TX QEC:
In my point of view :
I think AD9361 will ulitize RX Channel (or any internal RX loopback channel as AD9371)
to do the TX QEC cali, So I think the RX QEC calibration should be exectued sucessfully before TX QEC cali;
But when I read the API and SPI script, I found the recommend way is just to do the RX RF-DC&BB-DC calibration
firstly, then do the TX QEC, finally the API & SPI script enable the RX QEC tracking when the TX QEC cali was finished(see below pic);
So my question is if we do not execute RX QEC cali before TX QEC cali, how can we guarantee the performance of TX QEC?
