[sdiy] USB o-scope - just FYI

[Paul Perry]

Well that first one has a "bandwidth" of 25Mhz - but note the sample rate of
100M/S...
Doesn't that mean that if you are examining a 25Mhz sine wave, it's going to
have only four sample points on it?
You'll never be able to chase spikes with something like this..
(any EEs, correct me if I'm wrong).

I'd much rather have a secondhand 100MHz analog scope, which in some
countries can be found quite cheaply.
