Well, I have a really dandy 100 MHz analog scope I bought new
about 15 years ago. But, it is absolutely worthless for watching
transient events, like what happens when a circuit power up.

The advantage of a PC-connected product is you can print out
the graphs, or save the data for comparison with data acquired
years later. When I got the Link DSO, it really helped me out
with a bind building my servo amps. The instability and following
error was something that you needed a long data stream to
capture. Somewhere around 1/4 to one full second was what
I needed. The Link DSO goes up to 100 MSa/Sec, so it is
good for many other tasks, too.

My boss saw it, and imediately had me buy one for our project.
He can now monitor and control our experimental equipment
from anywhere with a PC, using PC-Anywhere to take over
the PC at the equipment site.

Obviously, it is a pretty expensive tool for one-time use, or
for hobby applications.
