Gary --
I just put one of these on my bench at the office (Tektronix TDS220).
Slicker 'n sliced bananna peel.
Been performing incoming inspection to qualify the new scope by making
measurements on an infamous recalcitrant Radiokit....
So, from one day's experience:
Display is much nicer than I expected, clear and bright. The scope is
small and extremely light and it will fit on the desk in your shack along
with the rig you're trying to test. Imagine slicing off the front panel of
a regular scope and filling it with helium.
Remember that it is a digital scope, not an analog scope. However, it does
sample at 1 Gs/s, so it really is usable at 100 MHz.
Has all the built-in measurement stuff that you find on the regular Tek
digital scopes. The user interface is the usual Tek interface, which has
evolved to where it is almost understandable. Just don't touch that
AUTOSET butto.....oh darn.
It does NOT have a dual time base. However, that is partly offset by the
long sample memory and pretrigger info. Unlike some previous Tek digital
scopes, if you change scale settings after you have captured a trace, it
will expand or shrink the trace correctly.
The vertical channels seem to have pretty high internal noise, widening the
trace like on the old 465. Of course, the TDS220 is in the same class as
the venerable 465, and I'm more accustomed to a crisp 2465B (at only four
times the price!). I'd rather have the TDS220 than the 465 any day.
Unlike the flat handheld scopes, this one does not run on batteries.
However, the performance and display quality is orders of magnitude better
than any of the handheld scopes I've used.
It's the QRP version of a Tek scope.
