About the influence of the EVM of the AD9361 by Tx/Rx frequency

Hi,ALL

 

We are evaluated using the board of AD9361.

By a combination of Tx and Rx frequency, EVM value of 64QAM has been worsening.

Rx frequency of open.

ex) Tx = 6000MHz, Rx = 6000MHz, 3000MHz, 1500MHz ···

      Tx = Rx / 2 ^ n

What do you think is the cause?

Is there a way to avoid the problem?

 

Similarly, Do you think EVM values become worse even if you change the Rx frequency?

Tx frequency is open.
