[R-390] Oscope tutorial

[Chuck Catledge]

One thing you might miss on the least expensive of the new digital scopes is they lack variable intensity.  That is, any trace, no matter how fleeting, shows up at full intensity.  The slightly more expensive versions usually add variable intensity, e.g. 128 levels, which very closely emulate an analog scope.
P.S. I still have and use my Tek 465 for vintage work...just seems like the right thing to do.

Hi

The 4” depth and extreme light weight are what sold me on getting one. The serial decoding and all the other features are things that I simply can not afford to get on a modern (made in China) US brand scope, even a used one. 

I’m not tossing out my 2465B any time soon, it just needs some help on the “lugging around” front.
