Basic Electronics » This a decent oscilloscope?

I'm asking because I really trust the collective opinion of this forum, but this seems like a pretty good deal: http://sacramento.craigslist.org/ele/1799244495.html It does have a minor problem that is listed in the ad:
What do y'all think? Worth it? Ted |

For $100.00, you bet. |

Phrank916-- Hold on-- Even at $100, it is NOT a good deal if it won't actually perform the way you need. Even at $100, particularly in this economy, this is a serious investment, and you definitely do not want to wind up with something sitting collection dust most or all of the time. There are things you need to understand (None of which are necessarily obvious) prior to getting an o-scope.
Don't get me wrong. I think $100 is a very good deal for an o-scope. You just want to make sure that you don't buy a problem. As for brand, I say tektronix. They are, and always have been the leader. Many, many tektronix scopes are out there on the market for a very reasonable price, that will do you better (IMHO). Just keep in mind, your o-scope should be able to accurately report voltage levels that your voltmeter cannot. Just my $0.02, so now you have an alternate view :D BM |

Good points Boba... My response was to the thought that for a C-note, it ain't a bad price considering what they sell for new. I have had my share of bad scopes in the past but when you don't have one and need one... well There ye go. The little Nano scope I bought a while back is all I have at the moment and in spite of the built-in short comings, it does what I need and is pretty darned accurate too. I would much prefer a 4 channel Tektronix storage scope but that is a bit out of the budget. There are always work-arounds if needed. |

Thank very much Mongo, and also to Boba: Your insight and expertise on the subject is appreciated. I've also read other info from Boba regarding oscilloscopes whithin other threads in this forum, and it's all very helpful. I've decided to hold off on an oscilloscope purchase and do a bunch more research before jumping into anything. Thanks again for taking the time to give me "shopping" advice, hehe! Ted |

mongo-- I agree entirely-- my big red flag was no probes. Depending on a person's need, that can get spendy. BM |

You can get a pretty good new scope for 372$ http://www.dealextreme.com/details.dx/sku.30573 |

Well, I am not sure, I was just glancing at stuff, but I think that the MCU output 20MHz. If so, that looks like one needs a 100MHz scope minimum. Someone needs to verify this however. I do know that this is the range of of any scope that I will buy one day in the future, higher if I can afford it, seeing as how that is really the ultimate ee tool for today's tinkerer, in my opinion. |
