I am trying to use about a 9 year old AD9910 Eval Board to generate a range of sine waves say upto 400Mhz.
Unfortunately, I feel there are issues with it. There is an output- though but it appears distorted and I am unable to get it locked.
The signal appears to be like a frequency modulated wave even if I am using this in the normal mode.
Checking the signal at the SYNC-CLK (J9) also one sees a similar waveform. This is puzzling.
Earlier when i was using Windows XP, it had worked well. But now I have upgraded to windows 7 pro version- 32 bit.
Would this be the cause of the misbehaviour?
or what could be the problem????
Thanks in advance.
