Hal,
Is the change cumulative? In other words is one tries 2^n times, could
you get there?
BTW. Thanks for your advice on scopes.
I finally ordered a DS1102. I had ordered a DS2072 but it would have
been 4-6 weeks till arrival, if then. In the interim, I convinced
myself a 2072 would have been a like trying to hold a tiger by the tail.
Play with the cheaper version for learning purposes. I was also turned
off by the metal heat sink holddowns popping off inside the unit. While
a repair would be easy, one would void the warranty. Turns out guys
have hacked the 2072 to turn it into a 2202 bandwidth et al.
