I took this screen shot from the AD9361 reference manual:
As you can see there is an orange block labelled as digital multiplicand.
Unfortunately I didn't find any explanation about this block of RX signal path in the manual, I suppose it's an NCO that does the down conversion from IF to BB.
I would like to get IF band signal out of the pink mixer in the figure above. Therefore, I need to apply an LO which has an offset related to the incoming RF RX signal. It would be great if somebody can clarify if there is an NCO on the RX signal path or not?
change TX to RX
