It is great for any kind of passive circuit with R, C and L. I also use it for active circuits, although I do not have data for all the common transistor types. it is very useful for testing a principles, but i find that sometimes the best values for components turn out a bit different in real life.
Rule #1: All Lives Are Final. Make sure that the life you have just been issued is appropriate for your needs, before departing the womb.
Rule #2: In case you don't like the life you have, see Rule #1.
Errr, John, didn't you point out earlier that the tube data exists, but that it comes in the from of an expensive plug-in?
Scratch that. I was gonna d/l the student version myself, and take a look at just how much it can be modified by a plug-in. Sadly, the above link takes me to where I should be, but that page is outta date.... there's no more getting a student version at all, according to OrCad's page.
Well, good ol' Google to the rescue. Just search for "pspice student download", and there's a raft of good stuff. I'm also gonna search for 'data plug-in", as soon as this d/l is done. ;D
