AD9129 noise on output after pulsed CW

Hello,

 

I have a problem with a board using the AD9129. I transmit a pulsed CW for a while and when I suddenly stop, e.g. I send zero's to the DAC, I see some noise appearing after about 1us, around 20mVpk-pk. Refer to attached screenshot.

When I only transmit zero's to the DAC, the output remains silent, no high noise shown.

 

Could this be some kind of artifact caused by the DAC itself?

 

Best regards,

Ingmar
