I put a signal of 605MHz in the RF input of the fmcomms card.
I use no-os driver.
I have create a Pcore that is connected to adc_mon_data of your adc block.
I try to acquire the I/Q samples with chipscope and analyse with matlab but I think there is a problem because I don't see I=cos(wt) and Q=sin(wt) as you can see on the linked file.
Can you drive me on the good way to solve this?
