content: I was thinking of buying a DS1054Z or D2072A, but it occurred to me that I would benefit more from a capable hand held scope with similar capabilities instead.I have looked at some of the Hanteks available and some of the models seem to be OK. The opinions and reviews on different hand held scopes seems to be rather sparse. So with this in mind I am looking for direct experiences, full reviews, or learned opinions on what might meet my wants/needs.I will be working on solar power generation and distribution, controls and electronics for stepper motors, servos, automobile controls and electronics, CCD cameras and associated electronics for astronomy, video signals such as old NTSC base and up to HDMI, and protocol analysis for micro controllers and their various forms of communication busses, USB1,2,3, etc. I think 2 channels are enough but maybe I need 4. I will be working on up to 1000VDC and down as low as ADC input values in the mV range. I would like to analyze things like CANBUS, SPI, RS323, RS485, and many other protocols. I probably will not need more that 100MHz bandwidth unless other see a flaw in my assumption. Maybe I could live with 60MHz.So, what says the herd? Should I just get a DS2072A and carry around a portable AC source to power it? Would this be the best bang for the buck for what I want to do? Should I look at a real hand held scope? Is it possible with a hand held to get most of the things I want without going over $800 for example? Perhaps a USB scope and a notebook?Thanks for any feedback.

content: I haven't used a Scopemeter in 10 year probably. Are they still using the easy to scratch plastic screen cover and horrid display?Not that you have lots of options in the handheld department, but for the price Scopemeters don't offer much in terms of value. If you need protocol decoding, Scopemeter is out anyhow.

content: While I like Fluke and the durability of their Scopemeter series, they don't really offer some of the features I think I need. I am not sure that any hand held scope will do what I want at any price. The Flukes are also more expensive than I want at this point, new and used. There are some older models for my price point but they are old tech and slow sampling etc.I am beginning to think that I might have to forget the safety of a fully isolated hand held and go with the DS2072A and carry it around to where I need it. I am still investigating online, but the decoding part makes it a long shot by the looks of it.

content: Thanks for reminding me about the input limits. The only budget priced hand held I could find with good high rated and isolated inputs is the Hantek DS1XX2S series. They look fairly good for the price but a couple of things I have seen seem to show that the Hantek firmware is buggy and some models are crippled by the firmware. They also do no protocol decoding at all. I found the DS1152S for $740 shipped on ebay. If I could find a tear down and a review of this series somewhere I would like to seem them. But until then it is a $740 gamble.The other option for me is to forget the "all in one" device and get a DS1054Z, a cheap handheld scope for looking at waveforms only in the field, and use the clone logic analyzer I have with my netbook when I need to decode things.

content: Quote from: tautech on October 26, 2014, 09:31:10 pmActually I would gladly buy a hand held scope without the multimeter built in. As far as I am concerned it is extra cost and they all seem to be poorly implemented and slow. They just add cost and complexity to what a scope should be. I already have a Brymen BM525 that does 87,000 data points at up to 20 times per second.The video I watched on the Sigilent model left me very unimpressed on the overall scope, and the multimeter was a toy IMHO.It seem to get a good hand held scope with isolation and a useful AT rating for the field, I need to go with a Hantek at $740 without decoding, or a Micsig for $1600 or so that includes decoding.

It seems that although you disliked some features, the later model was good enough that you repaired / replaced it with the same model when it broke.From comments you made elsewhere it appeared that you also owned a Hantek handheld, but I don't think you reviewed it. What was it that made you prefer the Owon despite the problems ?

In the meantime I rented a Hantek from Ebay.Hantek was OK but rather big.I think the Owon -N series are about the best performance vs. size vs. price for a handheld scope in the "Chinese" price range.Pity the built in DMM sucks so bad - just ignore it.

content: Mike:Yeah, I like knobs too. I can live without them if the scope has what I want for the price I want. I don't understand why hand held scopes have the horribly executed multimeters tacked on. It seems like a waste of space, time, and money.Pascal_Sweden:That Wens 540 is almost what I want. The problem is the scope is a bit low on bandwidth. Perhaps 10MHz is enough. The price that is mentioned on that video is a bit crazy though. I found it on Alibaba but the price looks like its close to $710 for one.I am considering the following non-optimum idea: DS1054Z + Uni-T UT81B or UT81C. This would give me the capability of looking at waveforms in the field on battery, and doing more detailed inspection should the situation warrant it. The missing thing is that the DS1054 does not have CANBUS decoding but the DS2072A does.

content: I have been revisiting the idea of getting a Wens 540 debug meter but I am unsure about the logic analyzer and its real usefulness in real life. The specs claim 50MSPS but only 10MHz bandwidth. So in real world use is this bandwidth really enough? Does anyone have an opinion of the limitations of the bandwidth in relation to the higher speed busses I want to inspect? The scope function is only 10MHz but has a 50MSPS which could cause some real issues with aliasing. Because the Wens 540 does not have a real scope input is reliably flat across the bandwidth? Nobody knows yet.The price is $700 USD approximately and I wonder if this is good value. The other concern for me is the oscilloscope has only CATIII 300V direct input but I would like to use this on solar systems where I might see 600V at up to 10A.I am really not sure that this debug meter is a good buy in comparison to other options or not. This is probably the first time in a long time in my history where I am not sure.I am still considering a DS2074Z as I want Canbus which the DS1054Z does not have, or a DS1054Z plus a logic analyzer with Canbus for the same price as the DS2074Z, or just the Wens 540 as an all in one device.To recap, my lowered expectations are that I want a portable solution for a 20MHzish oscilloscope, SPI, Canbus, I2C, RS232, RS485, 600V capability, but I still want to stay under $800 total. Is the Wens 540 the closest I can get, or is a multi-device solution a better idea?Any more opinions?

content: Quote from: Lightages on November 03, 2014, 12:12:01 amFirst off, that 50 MSa/s rate isn't terrible for comms protocols. That would give you decent edge accuracy out to about 10 MHz. But that BW means any digital channels above 2 Mbit/sec will be impaired, and above 3.3 MHz significantly so (not even the 3rd harmonic preserved). If seeing 5 Mbit comms signals as sine waves is OK, then fine.QuoteWell, the Wens will be of no use for HDMI. Or USB2 or USB3. CANbus will probably be fine (1 Mbit/s max there), but SPI may well not be. SPI these days is often 10, 15, or 25 Mbit/s (or more), and the Wens won't work there either. But that may not be the primary impediment, since there aren't enough channels to see more than one side of a SPI comms channel, and even then, only if there's no other device sharing the SPI bus (single Master, single Slave). That's because there isn't even a line available to conditionalize on the Select line. So you won't be able to separate out the merged bus traffic. This is even true on the $800 Rigol DS2000. The DS1054Z solves that particular problem, at half the price, and loses CAN decode.QuoteYou went from "I probably will not need more that 100MHz bandwidth unless other see a flaw in my assumption. Maybe I could live with 60MHz", to "Can I get by with 10 MHz"? Youreallywish you could get by with the Wens, but you already know you can't.QuoteIt's not so much whether it's a good value or not. It's not terrible for a combined functionality, portable instrument. The real question is if it will meet your needs, and IMO, your needs exceed its capabilities.QuoteThe 600V should not be a problem with 10x probes.QuoteI suspect you may be sure, but just don't like the reality of the situation. You have requirements that exceed the capabilities of the Wens, but still wish it would work for you. Because it would be an "easier" solution. I know the feeling.QuoteI think you meant DS2072A, because there is no 2074 or DS2000Z-anything.QuoteThe only way you're going to stay within that price bracket, and get close to the functionality you require, is with a DS2072A (and a long power cord, or inverter and battery backpack), or a stack of separates. Sorry to be the bearer of bad news.

How is your combination hammer/wrench/screwdriver working out for you?Luckily one wrench fits all bolt sizes too.Sadly (returning to reality), there doesn't yet exist an instrument that does everything, has great performance specs, AND is really cheap. Perhaps really not that surprising, when you think about it.How often will you need to be probing more than one channel? For those situations, a Picoscope 2105 (25 MHz BW, 100 MSPS) may fit the bill. It's extremely portable, and with your laptop provides scope, meter, spectrum analyzer, protocol decoder, and data logger capabilities. For <$300. More protocol decoders than the Rigols, and expanding.You can do some research here:http://www.picotech.com/handheld-oscilloscope.htmlSaelig has them for about 10% off MSRP.Well, rats. I see there's no 10x probe mode, so it's limited to +/-50V. Of course, you're not going to be looking at digital logic, or comms decoding, etc. at 600V, so a more conventional handheld may fit the bill for that part of your work.A Hantek DSO1060 at $365 will handle 10A, and 600VAC (800VDC). That's 2 channels, 60 MHz BW, and 250 MSPS. Has meter functions along with scope, but no protocols.The Owon HDS1021M is even cheaper, at $260, with current ranges up to 20A, and 400V (AC + DC). That one is 2 channels at 20 MHz BW, and 100 MSPS. Again, no protocols, but nothing else does either.These units are both battery operated, and work fine in the field. My Hantek DSO8060 has held up well over the years. They're certainly not bench-grade instruments, but they don't have to be. The screen is sharp and bright, but very glossy, which can be an issue with the sun overhead and trying to angle the handheld device. I haven't used the Owon's.It you really need the portability for your work, a Hantek handheld, plus a Picoprobe and your laptop, may fit the bill for ~$660. But that won't work for SPI, which requires a minimum of 2 channels. So drop the Pico and add a USBeeSX or Saleae (I prefer the SX), and get 8-channels of logic analysis, and lots of protocol decoders, with SPI up to ~8 Mbit/s or so, for under $200. Total combo <$550. The Hantek will run 6-7 hours on a charge, which since it shuts down automatically, mean you'll get all-day use in most scenarios. The decoders will run as long as your laptop does, and you won't have to drag the laptop into a situation where you're just reading voltage and current, or scoping out levels or switching signals.Hope this gives you some fresh ideas.

content: Thank you for the thoughtful and lengthy response. yes I meant DS2072A, just a mixup on all the model numbers.I like your last suggestion to get the Hantek and separate PC based logic analyzer. It is what I thought I would probably need to do. I just needed a reality check to get me off of analysis paralysis.Edit: I forgot one thing about the Hantek. I have seen some information online that the firmware is buggy and might not actually function as advertised. I was particularly interest in the DSO1062S which has isolated inputs. I will look at other alternatives.

content: Quote from: Lightages on November 03, 2014, 05:38:12 amI can only speak about the DSO8060/1060, which is what I have. The first one I got had numerous problems. Initially I thought they were firmware issues, but they turned out to be a hardware lemon.I got it replaced with another unit, and other than an occasional small glitch, that one has been fine for about 4 years. Back then, they were going for almost $700.Navigating around with buttons instead of knobs was kind of a PITA, at least at first. But that comes withe the territory on battery portables. I can't say the knobless Tek THS720A portable I had on loan was any more usable (monochrome, and battery life was MUCH worse).

content: Quote from: hgjdwx on November 03, 2014, 07:13:07 amThanks. That is an interesting looking unit. Nice to see them doing things with touchscreens.Unfortunately, the GDS-207 is priced at $1,200, which is beyond the $800 limit that Lightages specified. Also, it has NO protocol support. So that's really not a contender. Lastly, the battery life is considerably shorter ("up to 4.1 hrs") than the $360 Hantek. There may be other reasons to recommend it, but it fails on those counts.

Yes that GDS-207 is over my budget and also does nothing more than the Hantek models mentioned as far as I can see.Living in Chile is a risk to buy anything that might have a QC problem as it takes sometimes months for thing to arrive and then can take months to deal with if a warranty issue arises. That makes me kind of shy with the Hanteks because I have more bad written about them than good.Mike:Your review of your first Owon put me off Owon for good I think.So it looks like a Rigol DS1054Z plus a Picoscope or something similar to get most of what I want. It is too bad that there is nothing that does what I want yet. It seems like it would not be a particularly difficult thing to build now.

I already have a couple of Velleman handheld very low bandwidth scopes for doing some preliminary checks. I think this combination will give me many more options and capabilities.Too bad there isn't a really good AIO handheld yet for a reasonable price.

content: Saw a note about not buying from a WENS distributor because the margin is too high. We are moving offices in Sydney and are having a big stock sale coming up. Our margins are reduced because we'd rather sell stock before our move in late September.The WENS 540 is now $545 AUD +gst if you are in Australia. In USD it's about $395 USD at an FX of AUD/USD= 0.725That's a good price we believe. We have 7 of them at this price.It's here for on line shoppers.http://www.triotest.com.au/shop/handheld/3125-wens-540-10mhz-automotive-oscilloscope-and-debug-meter.htmlIf you are outside Australia or NZ we can supply but email us onsales@triotest.com.auto inquire if we ship to your destination.We are clearing out other items too and if you register on our site for the news letter we'll be sending out a list.Some of the clearance items are here.http://www.triotest.com.au/shop/303-clearance-itemsex-demo is here:http://www.triotest.com.au/shop/371-bargains-ex-demo
