PC Based Oscilliscopes
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. Thanks! Jim Douglas www.genesis-software.com Carrollton, TX USA 75006 Latitude 32.9616 Longitude 96.8916 |

Depending on what you are trying to measure,
they can be a very usefull tool. A "real" scope is much better, but much more expensive. IF you can, try before you buy. At the very least get to do a hands on demo. I use several different audio applications for a variety of my measurement needs. For the serious stuff, I borrow a good scope from work. The biggest "flaw" is they average the readings, so if what you are looking for is a rarely occuring gltich, a most PC scoes will miss it. For looking at normal waveforms they do a respectable job.

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.

It's STORAGE of waveform. When I was younger we had to put a hood over the front of the scope and use a Polaroid to get shots of easy to miss signals. A real storage oscilloscope costs a fortune, but if you can get a PC variety that fills your frequency needs, I'd go for it. Three or four hundred bucks is a bargain when accompanied by a good warranty.. mike |

You'd retract that EADG EADG I mean. sheesh..how hard can it be? I'm starting to suspect they shipped the wrong instructions with it, not that it matters, I can't speak Chinese anyway. http://www.clicmusic.be/images/hands_crossed_jpeg.jpg mike eadg eadg |
