Title: Difference between MSO & LA with scope
Post by: JoeBean on March 08, 2011, 03:44:00 pm
Hi,
Probably a simple and/or dumb question, but what, if anything, is the difference between a mixed signal oscilloscope and a logic analyzer with a built in oscilloscope?   I missed out on a fairly new Agilent MSO for a good price a little while ago, and since then I've seen some Agilent 16xx series LA come up on ebay for cheap and I was just wondering why 2 seemingly similar creatures would have different names.

Mostly marketing. The old 16xx HP's were basicallys LA's with scope add-on options, so the user-interface is likely to be more LA-like than a scope - a lot of the old HP scopes had poor user interfaces generally. The MSO name appeared when HP launched the 54645D which was a scope with digital channels and wanted a buzzword to distinguish it.

I would also suspect that the function that is mentioned second is slimmed down.

An MSO will be a better scope than a its logic analyser in the same way there is more pasta in 'pasta with sauce'. lol

OK, that history helps make sense of it. Thanks.

Isn't that always how it is?  Just like Mixed Nuts With [insert expensive nuts] are always 99% peanuts with 2 of the other nuts broke up and hiding in the bottom.  ;D Anyway, didn't mean to get off topic...
