AFE7950EVM: Is it possible to dynamically change the NCO frequency?

Part Number: AFE7950EVM

"TI JESD204 IP reference designs"
Located in ZCU102_AFE79xx_64b66b_12Gbps.zip
Input the signal referring to TI204c-Setup.docx,
I confirmed the behavior as attached.

I would like to dynamically change the NCO frequency during ADC sampling.
Can it be done with Latte?

    Hi Tatsuya,

    To dynamically change the NCO frequency after device bringup you can use the python command AFE.updateRxNco(chNo, Freq) # chNo 0-3. Please note that you should only update the frequency within the same Nyquist zone as the initial frequency for the Tx side.
