Hi Everyone, I hope you all are having a great holiday season! I'm looking for some opinion's/advice. I've been considering getting a Bitscope, which is the USB connected, PC based oscilliscope. Does anyone have any experience with these, and would you recommend them? I'm thinking of the BS310U dual channel, 100 mhz model. With analog probes, I'm looking at about $550. Thoughts? Thanks! Regards, Phil

And I'd like to ask for opinionsa on a similar gadget - I had been musing about the Velleman Two Channel USB PC Oscilloscope - I found it on line for about $350. (You might take a look at that too, Phil.) I haven't a clue as to how good these things are. I had thought that a sope like this runnung on a relatively cheap laptop, might make a good wave-form display for my synth as well as for testing purposes. I'll be looking forward to opinions. Thanks. Bill --- In motm@yahoogroups.com, "Phil Peery" <ppeery@...> wrote:

Hey guys! I'd looked into the PC-based digital scopes and they would probably be more than adequate for audio frequency work. Both of these have been reviewed in the various electronic magazines and the Bitscope has a users group like this one. Check out the archives or just sign up. A good dual channel scope is very useful for fast troubleshooting and prototyping - though not entirely necessary. Here's what I use daily - Paul S. will get a good laugh!: A very inexpensive Leader LCD100 digital scope with a built-in DMM. A 200kHz device, it is always on when I'm playing with the synth and testing new module designs in real patches with other modules. I picked it out of the trash at work during a 5S frenzy. It's very handy! A teacher gave me an old Speco FS4820 scope when I was a student. He claimed it needed repair. I calibrated it and use it all the time. I actually bought (with money, no less. Don't say a thing, Mike Marsh!)a B&K 35MHz dual channel scope. I got it a local hamfest for $45.00 and gave it a good cleaning. To find hamfests in your area, check out http://www.arrl.org or ask somebody that looks like an amateur radio operator and ask. We're easy to spot - picture Paul S. with about 75 more pounds, ill-fitting clothing from the local hardware store, and a bunch of electronic stuff hanging from his belt. I only wish I were kidding. <sigh> Chub - KG9MS incognito --- In motm@yahoogroups.com, "wjhall11" <wjhall@...> wrote: > > And I'd like to ask for opinionsa on a similar gadget - I had been > musing about the Velleman Two Channel USB PC Oscilloscope - I found it > on line for about $350.

I bought one of those "light comes on but I have no way of testing it further" deals on ebay for 21$ and 5$ shipping, and miracle of miracles it worked! And still does! And my wife never complains about the price of 300's, but asked about the scope, and I was able to show her it cost 21$, and she was impressed, I think. Or it might have been her "what the heck is that" look, it's sometimes hard to tell.

I bought one on ebay for 35 dollars and it works great a dual trace 20mhz... only problem is it starts to put out a funky smell after it is turned on for about 5 minutes, I cant figure out the smell but I hate it. It is not like a capacator or something electronic, really weird. I am affraid to open it up due to possible high voltages. I dont want to get fried over my cheap-o oscilloscope. I have seen 10 mhz single trace small oscilloscopes on ebay for buy it now of 150 brand new. I thought about getting one of those and putting it in my cabinet like Keith emerson had on his modular.

It would be a good idea to open it up, John. Leave the power off and look for something obvious. It may be that some crawled in and died (you'd be amazed at how often that happens)or something was spilled into the unit. Perhaps something has been jostled out of place and is now resting against the CRT or some other heat producer. You'd want to catch that before it fails. If you keep your hands away from the plug at the end of the CRT and any of the high voltage terminals (which are seldom exposed) you'll be fine. With the power off, you may still get a shock, but it isn't likely to kill you. Of course, you could end up like me - babbling about picking things out of the trash and attending (good grief) hamfests. As for a simple "module-like" unit, there are a lot of handheld and portable digital units around for cheap. My Leader LCD100 is about 5"Hx7"W and 1 1/4" thick. It's all wrong for a module but the price was right! I just had to reach into a waste barrel. Often the analog mini 'scopes are expensive, and "well traveled" because of their portability.

You definitely want to open it up and take a look. Arthropods are attracted to the warmth of electronic devices so it could literally be a "bug".
