Here is a problem with AD9970.

 

Everytime when I included 0x005 ( VGA gain ) into the program at the beginning of the program or at the end of the program, entire AD9970 stopped working.

 

What is the problem with this?

 

The attachment is the captured image, what is the reason for those horizential lines?
