For some dumb reason I have several of them, I have the HP 5004 and 5006, a bug trap sig analyzer and a Kurz Kasch model. All are basically about the same, at least as much as I use them. Honestly, I find I seldom use signature analysis. About the only time it really comes in handy is working on vector mathboxes. But it's nice to have it for well documented projects, like the cinematronics boards.

Analyzer. What is the one to get? I keep seeing people talk about the HP 5004A, is that was I should be targeting? I'm sorry if this has been discussed to death already, I just now finally joined this list. Also, what should I expect to pay for one? Thanks, Jon
