ADF4158 N-DIVIDER/2 of MUX out

Hi all

Is it possible for us to evaluate the function of the divider alone using the PLL evaluation board,w/ EVAL-ADF4158EB1Z?

For example, observe the N-DIVIDER / 2 output of the MUX output with the RFin input.
Specifically, the RF signal is input from SG (Keysight E4438C) to RFin, and the N-DIVIDER / 2 output signal is acquired from the MUX output.

The question is
In this measurement evaluation, what is the duty cycle accuracy (frequency accuracy) and phase stability of the N-DIVIDER / 2 output signal?
Are there any precautions?

Best regards,

sss
