Hi!
I am using a TSW3100 together with a DAC5682z.
Having some trouble figuring out why the change in interpolation and Y2 divider alters my output spectrum so much, which you can see in the pictures below. Can someone first explain what the Y2 and Y4 dividers do?
The signal is a basic two tone (1 MHz).
With 2 times interpolation and Y2 set to 8:
With 4 times interpolation and Y2 set to 16:
In the picture above I forgot to change the frequency for the two tone and thus it is half compared to the first picture.
Thanks in advance!
