content: Hello everyoneive been in the hobby sceene of ee for at least 10 years and from the very beggining when i was low budget and i needed a scope, the hantek usb scopes were considered crap...the years passed , i got my self a ds1054z (best vfm ever spent) and this got me into ee university. Now i realy had to downsize my lab,made my self a small set of instruments (lab psu , soldering station etc)but , the oScopes on the market are still bulky and expensive.I cannot justify getting a second rigol (or similar) for the projects i will do here , its too bulky and too expensive .Thus i turned my attention back to the hantek usb scopes .I mean ... they cant be that bad , they sould be able to "see" a uart or a slow analog signal ..right?

content: They have a wide range of models. Lower end models are really bad. More recent higher end models are decent. Enough to observe UART for sure.But their PC software is not everyone's cup of tea. So, I would download that and check if it has some demo mode or something like that to see if it works for you. But in a pinch, it is workable.

content: If you want cheap then for non-repetitive communications type signals a $20 USB logic analyser with the Pulseview program works OK.For analog signals in the audio range, a PC analog microphone input together with the Audacity software gives you a 20kHz storage scope.

content: Quote from: finos on August 25, 2022, 06:01:37 amIt depends what you mean by bad. Yes they can handle low frequency stuff reliably without stressing USB streaming bandwidth or S/W triggering, but if you consider high noise level and lack of AC coupling, is that bad? (There is alternative s/w and a hack in the Hantek thread to add on AC coupling now. High noise is still an issue though). The other one to consider is the VDS1022I, it's more expensive, but has reliable H/W triggering, twice the sample rate, low noise, ok s/w (florentbr's alternative is pretty much perfect) and galvanic isolation.https://www.eevblog.com/forum/testgear/hantek-6022be-20mhz-usb-dso/https://www.eevblog.com/forum/testgear/owon-vds1022i-quick-teardown-(versus-the-hantek-6022be)/Seconded on the $20 (I think you can get them closer to $10) 8 bit USB logic analyser. An ideal accompaniment for monitoring longer data streams.

content: You might be better off with something like this:https://www.eevblog.com/forum/testgear/fnirsi-1013d-100mhz-tablet-oscilloscope/msg3022032/#msg3022032https://www.aliexpress.com/wholesale?SearchText=fnirsi+1013DIf you want somethingreallycheap to just "see if something is happening" at low frequencies then you can go with something like this:https://www.aliexpress.com/item/1005003839624513.htmlhttps://www.aliexpress.com/item/32973233356.htmlThey're very limited and youwon'tenjoy using them, but they work.

content: never heard anything good of hantek usb scopes, mostly the software side ?you have good bench models scopes, and hackables in the bandwith, it would be a better investment

content: I’m struggling to see why you don’t bring your Rigol and shove it under the bed or something? The USB won’t be as nice to use. Picoscope is an option if you want analogue traces and decoding, but economy model(s) have constrained bandwidth.

content: I have some good scopes, but I also have the FNIRSI 1013D (badged "YEAPOOK") -- I just wanted to see if it could be useful.It is quite useful! I use it to look at slow digital and analog signals. It isn't much good above 10MHz but above that you can still tell that something is going on. The trigger is adequate. It's cheap and small, and I'm glad I have it.Even that tiny scope Fungus mentioned ($34 at Amazon, includes a scope probe) looks like it could be useful for simple work. I'm tempted to get one -- I already have a TinySA and a NanoVNA for when I don't want to fire up the good stuff.

content: Quote from: adam4521 on August 25, 2022, 05:58:09 pmDon't know what the story is with this OP, but getting older, and having issues with health I understand why the need could arise. The handheld Hantek 2072 been really good when working at a table with a niece. Nothing bad at all to say about the functionality and value of this. Recently got a OPWON HDS2102S which it also great when working on small projects at the table. I would prefer either of these multi-use handhelds over a USB scope esp if size & space is a consideration.
