Probleme with I/Q samples fmcomms card

Hello,

 

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?

 

Thanks
