Sometimes,the AD9164 is no output when sweeping frequency at 2.4GHz or 4.8GHz.

Hello, Can you please help me with the problem I meet .

When using AD9164 outputs 1GHz to 3GHz RF signal, sweep frequency step is 50MHz, sometimes AD9164 changed to no output at 2.4GHz and then all frequency is no output.

Change the output sweep frequency range to 3GHz to 5GHz, sweep frequency step is 50MHz, sometimes AD9164 changed to no output at 4.8GHz and then all frequency is no output.

Sometimes, AD9164 changed to no output at other frequency, but the probability is very low.

After restarting AD9164, AD9164 output get right.

When AD9164 outputs 2.4GHz or 4.8GHz signal continuous,  this problem will not happen.

When change the sweep frequency step is 1MHz or 5MHz, this problem will improve.

When decrese level of output power, this problem will not improve.

JESD204B frequency is 4.8GHz, I don't konw is there any collections between it?

I don't understand  why AD9164 outputs 2.4GHz or 4.8GHz signal continuous,  this problem will not happen.

I don't konw how to solve this problem and I need your help.

Thanks and regards
