I purchased a warp eval kit3 board and i have some problems with it , the noise from the ADC looks like a sine wave ,
I changed the channel frequency (band 5 ghz) but i get always the same result , is this due max2829 or AD9963 please help
attached image in following link
the red is imaginary part and blue is the real part
What is the serial number of your kit (W3-a-NNNNN)? I can check our records for its manufacturing calibration data.
Are you using one of our reference designs (i.e. WARPLab)?
no I use a custom code and i delete every thing in the eeprom, did you see this phenomena in other board
please can you tell me the procedure to correct this issue

The serial number is also printed on a label on the top of the board, just to the right of the SO-DIMM.

I would recommend starting with our WARPLab Reference Design and verifying the Tx/Rx I/Q signals are clean with this known-good design. Otherwise you'll have to provide more details about your custom design for us to help. A sinusoid in the Rx I/Q signal could be caused by many things.
in my design i configured the ad9963 and max2829 and the clock generator as described in your code , the transmitter path is functional , the only problem is with rx path ,
A sinusoid in the Rx I/Q signal could be caused by many things.
can you list this things that can cause this problem
