Maybe someone could bring a function generator to the next meeting and we can bring our new scopes and test them out? It would be nice to have someone familiar with digital scopes give me a quick primer on their use and functions as well as to compare the various models.
Sova From: [email protected] [mailto:[email protected]] On Behalf Of Jason Barnett Sent: Sunday, August 10, 2014 4:46 PM To: A discussion list for dorkbot-pdx (portland, or) Subject: Re: [dorkbotpdx-blabber] Looking for input on oscilloscope Jerry, Sova and Paul, thank you for your input on Aliexpress and the MSO5074FG. Paul, I had not seen that thread on eevblog. He posted an update the day after you gave me the link, saying his unit was replaced and he has been quite happy with it since. While $500 is not cheap, it is within my "toy" budget, so while I would not be happy if it turned out to be a complete dud, it isn't going to break me either. After all of my research and weighing the risks, I think I will go ahead and order this scope, albeit using a creditcard with buyer protection and a bit of nail biting. I was able to find it for $500 and free shipping, so if there is a problem and I get a refund it should be the full $500 instead of $430 + $80 for shipping. This unit is a bit of an unknown, so it will be exciting to see if I end up with a dud, a gem or something in-between. Thanks again for everyone's help.

I'm really curious to see it. There's so little info about this scope, like whether it does intensity grading and how many waveforms/sec it captures, if it does. Reply #8 on that thread claims to have more info, but I can't see where he got it, and it doesn't make much sense to me either. He believes it captures 2000 waveforms/sec, but the he says there's no intensity grading, which doesn't make much sense to me. I do not believe any TFT LCD is that fast, so how could 2000 waveform/sec work without rendering to intensity grading? But this page has a number of screenshots that look like they might be intensity graded? http://www.aliexpress.com/store/product/High-quality-Hantek-MSO5074FG-70Mhz-4-Channel-Oscilloscope-8-Channel-Logic-Analyzer-25MHz-Arb-Waveform-Generator/100653_1596199238.html But those screenshots look nothing like the images on the product photos, which look less like photos and more like illustrations (gray in the illustration/photo, bright blue in the screenshot). I couldn't find anything that looks like a real photo of this scope actually in operation, other than a splash screen, not the 'scope's actual waveform display. So much mystery! If $500 is a lot of money for you, I'd recommend waiting. Early adopters can really suffer, especially with brands like Hantek. _______________________________________________ dorkbotpdx-blabber mailing list [email protected] <mailto:[email protected]> http://music.columbia.edu/mailman/listinfo/dorkbotpdx-blabber
