Hi,

My config :

- Zynq 7000-AP SoC mother board

- FCOMMS3 RF board

- IIO Scope.

 

OL Tx 5 GHz

DDS CW Tone ~1MHz

(screenshots attached)

 

Tx spectrum image attached.

Except the residual carrier and the image frequency, where do all other spurious come from ?

How to reduce them ?

 

Thanks
