I do my analysis on the spot.
Why make a scope print out or make a file?

I do. A lot.


I imagine the graphs might be good for published technical papers.
But what else?

Documentation, problem reports and so on. For example, my module specs often contain real-life scope plots along the lines of "This is the waveform you should see at the secondary of TR12". Then lots of investigations for clients. "Look, this is what a transient on the powerline does to the XYZ bus".


Maybe I can email somebody someday with a scope pic and write "
Seeee...it makes a glitch! "

Au contraire. Almost every day I receive scope pics from clients, asking me what the cause of the glitch, jitter, whatever could be and requesting mod suggestions. Without those plots I'd had a hard time helping them, short of hopping on a airplane and visiting them. I can consciously say that the ability to quickly exchange scope plots has avoided dozens of costly business trips over the last few years. Those to the east coast can eat up almost a whole day just to get there. I only charge 50% rate for travel time but boy does that add up.


Also, I can't recall the last time someone posted an oscillograph on
SED. IIRC, awhile back, JL's post was a digital cam pic :)

The last time was this morning at 6:16am by Jamie Morken.


Is 'Scope on LAN' practical?

Absolutamente. Although USB works fine as well. GPIB is a royal pain in the neck.

Until the first virus shows up, and your scope turns into a pumpkin, two days after the warranty expires. It's USB keys plus Sneakernet for me.

I think your PC must have a virus, it is posting messages twice :)

Rats, and I was posting from my scope. ;)

Joerg, I agree completely about Windows scopes...but you can't get really quick digitizing scopes without it. :(
