In the market for a scope

[Harry Bissell]

Hey Toby:

Excellent point.

I use a Fluke/Phillips hybrid scope at work. My favorite... like it even
better than
the TEKs. It has digital storage, but push a button and it becomes analog.
Crude
but excellent "sanity check". Make sure its real, then sample.

There is room for analog and digital !!!
