Well, I wanted to get a feeling about upper and lower limits, over a
19.7 octave range I had pretty good tracking. The thing was that I
only noticed these things as I got up there, but later I could find
them when looking for them at any frequency.

Well, one learn to apprechiate these features the more one uses
them. The scope was bought to troubleshoot more or less digital
curcuits but this is what I use it for during the weekends ;)
