Hello,

I have a AD9850 module and I am having issues with the output at medium frequencies. I have a good waveform both Sine and square wave up until 20Khz.
After that I get DC offset, and it get worst as the frequency increases. At 1mhx I get like 600mV offset for a 145mV signal.
How can I remove that DC offset.

It was a faulty module. works good now when I swapped module.
