AD9361 Harmonics problems

Hello,

Attached photos are describe spectrum image of “ADALM PLUTO” module, TX output chain.

You can see very Strong odd harmonics.

It is important for us to understand if these harmonics can be filtered in the level of the chip? ( I guess not).

Additionally as we discuss few weeks ago together with Eli we need to know if this issue exist also in ADRV9002?

Thanks.
