content: I was blown away by the DS1054Z (as were many), but this seems even less believable:https://www.circuitspecialists.com/digital-storage-oscilloscope-dso5202bm.html?utm_source=dso5202bm&utm_medium=email&utm_campaign=emc00047&utm_source=Circuit+Specialists+Newsletter&utm_campaign=0cf04aeb99-EMC00047_8Sept2015&utm_medium=email&utm_term=0_dd242259e3-0cf04aeb99-53181033&ct=t(EMC00047_8Sept2016)&mc_cid=0cf04aeb99&mc_eid=8f5a06fcccHantek DSO5202BM, 200 mhz, $351.20 and free shipping?The site doesn't look sketchy, so...? Is there some drawback to the Hantek that isn't obvious to me?

content: If you think that is an incredible price, knock yourself out with another $100 off and get the 70MHz version, e.g.https://www.amazon.com/Hantek-DSO5072P-Digital-Oscilloscope-Bandwidth/dp/B00RJPXB6YThen upgrade it to 200MHz with the well known software hack (search for tinhead's mega thread).But I would still choose the DS1054Z which also has a well known bandwidth hack any day unless money is really tight.

content: I have the 1054Z and no plans to change, I was just looking at quadruple the bandwidth for less money. When I was shopping DSOs last year and bought the Rigol I thought anything 100Mhz or higher was way more expensive. Seeing this at roughly the same cost as the Rigol was just a little shocking, but it makes sense if it has fewer features.Makes me wonder what the insides look like, what Dave would say about the hardware.

content: Yeah, incredibly shitty 200 MHz scope.

content: Quote from: MacbethI'm not so sure that it's *just* a software hack. I have the MSO5074FG and the analog switches are only 70MHz rated; It would need a part swap (and there are also some minor tweaks to the gain resistors to flatten the response) to get reasonable output. These are also on the same megathread I think...

content: Quote from: jimdeane on September 08, 2016, 04:06:43 pmI've had a 5202B for years ever since they came out. It's been a great scope for debugging and product development and at the time the price/performance was unbeatable. No doubt there are better scopes out there now such as the new Rigols but recently I had to check some SDRAM timing and the 200MHz bandwidth limit makes a 100MHz clock signal look like a sinewave so I have had to get in an old Tektronix TDS700 series war horse that I purchased from ebay recently. Unlike the Hantek it has 1 GHz bandwidth, 4 channels and up to 4Gs/s sampling. I would have like a 2GHz bandwidth but price starts increasing exponentially even in the 2nd hand market ! It seems that once you get above 500MHz that space is still dominated by the giants in test equipment and so is the price !!Limits of the Hantek was that the AC coupling was weird in that it would start rolling off at 100Hz and it could do with an extra 2 channels !!cheers
