COULD IT BE?
There are three ranges noted on the back label. 50k-300MHz, 300MHz-900MHz, and 0.9GHz-1.5GHz.
If my stimulus start and stop crisses over one of these ranges then I see this happen.
So this may be a feature I never heard of instead of a bug or problem.
Maybe me talking to myself will help some poor bloak searching the threads someday. lol
