In article , james.douglas@genesis-
software.com says... Anyone use these? Any recommendations good or bad? I am looking at some that have Scope, Meter, Spectrum Analysis, etc. Are the "multi-use" type PC scopes any good? I see some that are down around $200-300? which is in my price range. My gut reaction when I see a PC-based O-scope is to cringe. I would stay away from them. For the same price range that you mention, you could get one heck of a nice Tektronix 7000 series 'scope, or perhaps a 400 or 2400 series portable, all from the used/surplus arena (more specifically, from ham radio swap meets or Greed-Bay). Example: The Tek 7603 was one of their most popular, and is also one of the most plentiful on the surplus market. It has a mainframe bandwidth of at least 100MHz, and can often be found for around $50-$100 with plug-ins. If you want some serious bandwidth, you should have a look at the Tek 7904 or 7104. The base frames have bandwidths of 500MHz and 1GHz, respectively, and you should be able to get a good 7904 with plug-ins for a little over $300. Your test equipment needs are, of course, your choice. However, I would like to say that just because a test instrument CAN be designed to work in a PC environment does NOT always mean that it SHOULD be. Good- quality input stages are hard to do (there's a reason Tek put so much R&D into theirs), and they are one of the main driving factors where cost is concerned. I have little faith that the Taiwan-import PC-based (alleged) O- scopes can do a proper job in this regard. Good quality test gear is an investment, and it should be treated that way.
