EEVblog #13 Part 2 of 2 - Comparison of PC Based Oscilloscopes

[@GospodinJean]

PLEASE, DO A NEW VERSION OF THIS VIDEO. IT WILL BE MUCH APPRECIATED

[@matteo234321]

YES, I'd love to see if your opinion has changed after 10 years.

[@vencibushy]

Dave, it's a bit outdated video now. Is there any chance to make a bit up to date version? Pc based scopes got a long way. Can they compete with a bench type oscilloscopes today for a given price?

[@Woolfy95]

+Ventsislav Simonov Yeah that would be good

[@giomjava]

I second this! The tech must have improved by a lot by today..

[@Taran72]

i looked up some digital oscilloscopes and find the information of the video still valid. the BW and sampling rate a way poorer of a bench model. In the end I think that the compromise depends on the application the scope is intended for so they may be good for one application but no good for another.

[@russoft]

g quinn clearly has an axe to grind. I was looking for a helpful discussion. Nope.

[@andreabianchi1099]

After some test I have done on 1008c hantek I can Say that: pure shit.

[@judclark7376]

I would love to see this subject revisited today comparing the picoscope line to some of the lower end scopes.

[@uni-byte]

Picoscopes are not cheap.

[@Zaikar]

Great video! But it's 10 years old, both oscilloscopes PC based and standalone have been improved quite a lot, being really cheap options on both categories, it would be great to see a video like this talking about today's scopes. Thanks!

[@EEVblog]

@fingerboy18 Yes indeed. Good quality PC scopes can be had, but they are not cheap.

[@voland4513]

Something like Picoscope, not cheap at all.

[@wapvirus]

EEVblog would you please consider a quick review on The DSO 168 DSO168 Handheld mini pocket portable ultra-small digital oscilloscope 20M bandwidth 100M sampling rate s.aliexpress.com/YjyMzURf?fromSns=Copy to Clipboard Please check this out

[@christianaylward7997]

USD $299 for a 100MHz 1GS/s USB3 scope with 1M record length ain't too bad...DSCope U3P100

[@geoffreyolson9720]

the multichannel pc scopes with high vertical resolutions are ideal in automotive diagnostics. The vertical resolution is more important than the sample rate from what I've seen on scopes for auto use. Getting a high res waveform on a pc display makes it easier for me to tell if there's a pintle valve sticking in a fuel injector or a secondary short in the windings of an ignition coil etc.

[@RSP13]

Geoffrey Olson I see your point, but I think he had in mind a GENERAL USE oscilloscope. Of course it may not be the right answer for every case.

[@alexsimonetti8522]

Funny thing is that the most expensive oscilloscopes, like the AUD$ 140,000, 13GHz Oscilloscope you unboxed in another video, are basically a PC with a custom motherboard and a few other gadgets (like data acquision cards), but with all the bells and whistles of a regular Windows XP PC. Many other high-end meters are also PC-based.

[@jimporfit]

FPGA is a common core

[@stawmy]

I recently got a Hantek 1008 because i needed to see and sample up to 8 things at once, and it was the cheapest :D It has all the engine diagnostics but all i needed was the scope mode, and i was very impressed. Both the sample rate, real time display and bandwidth were good, the software very easy to use and you can do math functions, period & frequency on the channels. It does have drawbacks, the screenshot mode has a big delay so if you are trying to capture a pulse it takes many goes, and you can record but that also appears to be somewhat limited, and the worst thing is that it will crash given too much data, like 8 complex waveforms at once. But for 90 Euro's it's a snip. I like the custom screen so you can alter the background colour. I used this on an old laptop together with a spectrum analyser and second monitor. It worked, but only just! Some of the voltage ranges were also wildly inaccurate, but as a visual aid it works very well.

[@EEVblog]

Sorry, found a video/audio problem in Part 1, will have the render it again tonight and re-upload.

[@Thefirstscallywag]

I agree that an update would be nice.I picked up a Hantek 6022be for under $100.Basically I was afraid of frying a +$300 oscilloscope due to inexperience.Woks fine for my purposes and learning.Will probably upgrade later when I have more confidence.

[@incalify]

I agree, a new version of this video with the updated versions of the PC scopes is needed. Please do it. Your observations are useful and valuable for us. Thanks in advance.

[@powder-phun949]

And there is one more thing - physical knobs and buttons. Am i the only person who likes turning knobs?

[@GregWoodsLancs]

6 year on, still a valid comment. Especially when PC scope software tries (and fails) to copy rotary dials instead of being designed for PC, making full use of mouse, keyboard, and these days, touchscreens

[@ianswitzer3395]

For someone who is unable to pay very much money, less than 200$, it appears as if a pc based scope is the best for me. My only other alternatives are "pocket" scopes and other usb scopes. In comparison it seems this is the best for me.

[@DrTune]

The Rigol DS1052E really is pretty great; I finally picked one up to replace my $90 ebay analog scope, it's exceptional value for money

[@bgable7707]

Yes Dave, it would be great to see a new comparison. I've just started getting into "hobby electronics" do to some interest caused by the IOT rage and my applications background. 10 year in tech goes a long way. However, $$$ is more than I'm ready to JUMP into. Please advice via a new video. Thanks for all the hard work on all your other videos!!!

[@crusader2.0_loading89]

Did you buy an oscilloscope?

[@SDTricker]

I just got a 50Mh Hantek in today. I was really scared it wasn't going to be good enough, but I was really surprised at how easy it was to use and decent it was. The square waves did start to curve out around 1Mhz though. :( I guess I should have gotten the 80Mhz. Otherwise, it is really good for the price.

[@HillsWorkbench]

Bought the Instustar for about $60. Agree with the calls below for a re-do update or whatever. Scope works well, the FFT is better than my Rigol DS1054. Prices are down, performance is better.

[@A1Googler]

The equivalent-time sampling method allows a DSO to have a bandwidth that is higher than its sample rate, which in fact many DSOs do.

[@schmudge]

+EEVblog would it be worth updating this or is this still valid? cheers (or have you done it??)

[@ACTSRevolution]

still helpful for this N008!!! I would like to know why max freq input is never specified. What if i want to analyze an RF waveform for a signal frequency of 10's or 100's MHz - can anything do this? Is this not a use of older scopes, maybe only newer scopes? Maybe an update to this vid could do a better job of educating the broader YT audience.

[@HermanWillems]

@g quinn PC scopes will be the standard. Because you can script them. You can put also the data into data analytics software. You can get advanced analytic algorithm which you need alot of CPU power for. Post processing is cheap on a computer. The USB Scope just has do have good specs and a huge memory buffer. The rest of all functionality can be achieved by software on your PC and updates.

[@sc0rpi0n0]

Likewise, it applies to other tools as well. Choosing the right oscilloscope is crucial, much more crucial than choosing a solder iron. There are many more specs to look at, and as a teacher, you're totally obliged to inform your students about it.

[@leisergeist]

Damn, the tech has come a huge way since 2009. The Analog Discovery 2 is pretty viable IMO.

[@HermanWillems]

And also the PicoScope. He should do a revision on PC based scopes because these days on work and everywhere you have PC's. 24 inch monitors are cheap as hell. And Computers cost NOTHING anymore. You have much larger memory to store history. And a larger detailed screen. The Analog Discovery 2 is pretty viable for students. But it's not doing negative voltage reading which is a bit sad. But for educational, it's a machine that can do Scope, Function Generator and digital signals. Even thought the specs on paper are great. I doubt it has good accuracy. The software is also great of the Analog Discovery 2. For it's money its worth it very well for starter. I also looked into it, but now im looking into PicoScopes.

[@camelCased]

@@HermanWillems And also VDS1022I is pretty nice for occasional hobbyists. Still, I wish there was a USB scope that can rival a budget Rigol for an even lower price (because a USB scope has no screen, no knobs, and also it has less complex firmware, delegating the input/output logic to a computer).

[@duncanyoung8688]

And people may not want to drag around a big heavy expensive bench scope.ive a pocket scope and does me fine,£30 fit for purpose

[@ZeroMass]

He's speaking of quality and function, not if it comes with a cup holder or fits in ones shoe. Further hes helping folks new to electronics, what is important, and the factual differences. You on the other hand are just spamming the comment section with drivel.

[@RWoody1995]

+Duncan Young I doubt a £30 scope is going to be all that good... an oscilliscope is a serious piece of equipment not a toy to play with

[@revolutionaryrocket2677]

The best oscilloscopes are often found on eBay. I bought a 100MHz HP 54600B CRO, l optioned up witht eRS-232/automation module, in calibration and in perfect condition for $A 230 delivered to my door. This CRO has wonderful triggering and is a delight to use.

[@markharrisllb]

I have a Hantek 6022BL and it’s helped me learn. I've just bought a Siglent SDS1104X-U and even if I’m using all four channels it's 5 times more powerful than my Hantek and it does lots of things I don’t understand. I only ever do small projects and never do anything over demanding. However, perhaps I should have got the SDS1104X-E…?

[@revolutionaryrocket2677]

The author metioned using PC based data acquisition. Latency and slow speed is usually the issue with low cost DAQ boards.

[@peterjohnson5586]

You should do another one with the current USB scopes.

[@judgenap]

Hi EEVblog, Thanks a lot for your great information . It was a year ago since you made this video. have you seen more up todate scope. I am ready to buy

[@dabrusterguy]

Here's why I feel I need a PC oscilloscope: I go on engineering trips, and I cannot bring a huge amount of equipment. Plus, the equipment I do bring gets tossed around, which includes a lot of sharp tools, and I don't want something which is heavy or can get damaged easily. Furthermore, it's rare I actually need an oscilloscope on these trips. I always bring a laptop on these trips. Under these conditions, would you recommend a PC oscilloscope?

[@uni-byte]

It's been a while since you did this one. It would great if you look another swing at it as teh tech has changed. Now the Hantek 6254BD has 1GSa/s, 250 MHz bandwidth and a 25MHz AWFG all for about $260 Yankee Bucks Memory depth is only 64K, so that's a drawback, but the Siglent SDS1204X-E is only 200MHz and $700 YB but it might actually be 3 times the scope with all it's other features if you have the $$$. However, in the Hantek price range you simply cannot get a 4ch, 250MHz, 1GSa/s scope from anyone anywhere.

[@Necrocidal]

How do Picoscopes compare nowadays to traditional oscilloscopes, especially considering the extra connectors and licenses that some scopes need in order to do what Pico's get built-in? How does the performance compare for "final" cost of a setup?

[@Dan-oo1rj]

That's the good question what I'm going through now. Looks like Picoscope is delivering quite good product, even for very huge money... (if somebody is willing to pay 20K USD per unit - must be aware of good and bad sides of the product) But what if they will stop providing software? I had that issue with Zeroplus logic analyzers. I've switched into Linux from Windows but their software for my device is only for Windows. Standalone oscilloscope will be always "standalone" and "self-sufficient" device.

[@Necrocidal]

@@Dan-oo1rj there's open-source APIs for Picoscope, so if they somehow decided to commit commercial suicide by discontinuing their strongest selling point, the hardware can still be used

[@Dan-oo1rj]

@@Necrocidal many companies "commited commercial suicide" by letting bigger fish to purchase them and then shut them down. :) My point was very generic, not related to the Picoscope only :) I have quite old oscilloscopes and they will work without PC, data connection cable and additional software. But no one can be compared with ability of the PC and it's UI on it's screen! :) Each way has pros and cons :) Probably I'll go PC way this time :D BTW - thx for the info about OpenSource UI for Picoscope.!

[@mikaveekoo]

I think that for measuring the basics (e.g. frequency response, noise) of audio equipment the pc scilloscope is competent enough.

[@themiln]

Hey Dave! Check out the Hantek DSO-5200A - Just under the entry level price of a proper bench DSO with minimal trade offs. It may be an acception to the rule! Your thoughts?

[@esavarem]

For around a thousand bucks you could have also for example tested an Agilent U2702A usb pc oscilloscope. It feels pretty decent to me, though sometimes I miss a good bench scope next to all the other instruments

[@nickofehunter1]

for the beginner to you feel that the lower rate could or would be sufficient, or is the higher rate is needed right away with using the scope for the beginner?

[@Chicken_Massacre]

Hi Dave. I have been thinking about buying a PC based oscilloscope. But there are so many to choose between. Is there any any way you could give an update on newer models of PC based oscilloscopes since this video is roughly 5 years old, and there might be some new chips available, with higher bandwidth. There are also alot of SMD made oscilloscopes available, are they any good ? I'm thinking of getting a cheap one, to start with since i don't have alot of money, because i'm in technical school, going for Electro Engineering. So if you could find the time for this, it will be greatly apreciated. Best regards from Copenhagen, Denmark.

[@satyamfifa]

Is Link Instruments MSO-19 and better than the PC based oscilliscops compared in this video ?

[@rgubele]

Hi EEVblog, Why does the sampling rate need to be 10x the bandwidth of the scope, instead of 2?

[@COASTER1921]

Imagine you have a sine wave and take 2 samples per period. Unless you time them to be taken at the maximum amplitude you will not see the true amplitude of the signal. Worse, if you take them at the zero crossing point, you will see no signal at all. To fix this problem we just take more samples. Take 4 samples in a period and you'll be able to guarantee second the frequency, but will still have amplitude problems. To fix that you double samples again to 8. This is where I consider the sampling rate to be effective, but 8 and 10 are very close so it doesn't matter much. Surprised nobody here answered this question for 7 years.

[@rgubele]

@@COASTER1921 I appreciate you responding, even seven years later. Unfortunately, that can't be correct. Those two samples will in fact define the sine wave mathematically, unless they were taken far apart enough that they are sampling separate oscillations or the sampling rate happens to be exactly the same as the frequency of the signal that you are measuring. This is basic signals theory stuff. The only explanation I can think of for why you'd need oversampling, and especially so much of it, is if oscilloscopes in general don't implement a sinc function and just do linear interpolation (or don't do any interpolation at all). If you're only "connecting the dots," then what you said makes sense. You'd have to take a measurement and then set down with a pen and paper or something to get a representation of the waveform. This could be the case, I dunno. I don't do a lot of electronics work, and most of what I do is pretty low frequency, so even crappy little DSOs are massively oversampling. Of course, if that is the case, then why stop at 10x? Is that just what practical experience tells you is enough?

[@COASTER1921]

@@rgubele If we only cared about the frequency you are correct. But for an oscilloscope you need the amplitude as well. Sample right at nyquist then decrease your frequency a little bit without changing sampling rate. You'll get some nasty aliasing and no longer effectively be able to tell the signal amplitude. You can easily verify this on a cheap oscilloscope that has a bandwith frequency close to its sample rate like the ADS1013D when you increase the frequency up to the 100 MHz maximum. With only 200MS/s the resulting amplitude is just plain wrong as you adjust frequency, and the effective bandwidth is really only useful up to ~30MHz if you squint a bit, though a bit less than 20MHz in my opinion since I like being reasonably confident with my measurements. There are lots of ADS1013D reviews out there and they all touch on this to some degree. I own an ADS1013D and love it despite these shortcomings. You just need to adjust the expectations to the price. Unfortunately even modern USB scopes often don't hold up well and have these same problems if you only plan to use them as an oscilloscope. The reason some are a compelling value now is due to the crazy amount of other features built in (i.e. Analog Discovery)

[@rgubele]

@@COASTER1921 This still does not sound correct to me. The amplitude would be encoded in the two samples as well. At Nyquist is a special case, as mentioned, but any other error would presumably be quantization error. Unless you're using an oversampling system and/or not doing sinc interpolation or your signal is not band limited or something. So what is the "something"? I recommend this video. It's dealing with digital audio, but the principles are the same: xiph.org/video/vid2.shtml It sounds like what you are describing is not aliasing, but rather the result of bad (or perhaps "not useful" is a better way to put it) interpolation, bad (or nonexistent) anti-aliasing filter, or something else. Not having an anti-aliasing filter seems likely, as it's difficult to make a good one that is compact, but I dunno. This is not really my area of expertise. And it sounds like 10x is just a practical rule of thumb drawn from experience. But it would be nice to have a confident answer on this. Wish EEVblog himself would expand!

[@jbpost52]

I have a question, first of all I know very little about osilicopes but I am starting to learn to use one for automotive diagnosis. The industry uses Snap on and Pico scopes. Would there be a problem using a bench scope for use on automotive? The scopes for cars seem to be very expensive. The voltages measured in the automobile secondary can reach as high as 50k volts. Any suggestion is appreciated.

[@SaptarshiGhosh7]

Jan Post - Other than portability I don't think there is going to be much difference. As long as higher voltages are considered you will need to get special probes that can handle voltages like 50kV. Normal ones can handle probably 300V depending on the CAT levels. I don't remember top of the head. Check manufacturer datasheet for the probe specs. You said that voltages go upto 50kV range. Just curious, where the voltage gets this high (Ignition coil/Spark plug)?? I'm asking coz I'm not from automotive industry.

[@jbpost52]

Saptarshi Ghosh Yes the secondary of the coil can reach as high as 50k .

[@ValExperimenter]

Jan Post I have always used a 15Mhz analogue scope on cars, the HV can be reduced by a simple clip on capacitive divider to 10's of volts this can be home built from a clothes peg and some 10mm copper tube split in half, the LV side of the ignition coil can be handled by a x10 probe. Injector pulses and trigger pulses are easily displayed on a bench scope. The main disadvantage of an analogue scope for automotive work that I find is they are not so easy to read at low sweep rates such as when the vehicle is idling. A large and bright screen is handy in a workshop

[@RC-Heli835]

Hey Dave, is the Rigol DS1052E suitable for auto diagnostics? Damn this is already 6 years old. Where does the time go?

[@ProfessorVector]

Not to mention when windows get updates win7,8,9 etc they lag behind with drivers and software updates. Right-on man, get a real bench scope, very well said! And many times you need your pc to drive you hardware and nothing beats real buttons not using you mouse to start some app, download it and then capture it.

[@rtybn2012]

I have a TEK 7704A with two 7A26 plug-in gives me a analog BW of 200Mhz. I just bough a RIGOL DS1102E with a BW of 100Mhz and 1Ga/s I bough the DS1102E for the FFT function. I am going to compare it to my HP 8590B Spectrum Analyzer which is 9Khz to 1.8Ghz under the same functions. I like the RIGOL for its size and weight

[@allantamm2185]

Dave! You have a couple days to 10 year anniversary at 17 jun 2019. Do I have to wait another 10 years for a decent usb scope?

[@tentis2]

Hello EEVblog, I'm thinking to buy a digital oscilloscope, is it worth to buy the OWON SDS7102 oscilloscope ? I have already an analogous oscilloscope (Tektronix 2465B) but now I'm interested in a digital one, I hava no experience with digital scopes, I didn't even see them in the real life :-) Thank you

[@sasantnuthakki8659]

Hi EEV blog, I am looking for pc based scope which can read reflecto waveform (2 waveforms through single channel). At present I am using Fluke 105B, now it's very hard to find a used one for cheap. Can you advice.

what about us that want to test cars... Like the snapon that can read all computer sensors in one hookup? can you explain that .,, i am serious... Thanks

[@gordo8189]

Rigol start-up procedure - switch on -> wait 10 seconds for boot... PC-based 'scope startup procedure - Switch on PC, wait up to 5 minutes for Windows to load -> Updates required (DO NOT SWITCH OFF YOUR PC!) Wait another 2-25 minutes while Windows 10 updates -> Attach Scope via USB -> Driver Not Found (Windows was unable to find a driver for your device - damn thing worked on my old PC) -> Start Windows Edge browser -> Surf to PC Scope website -> Go to Support/Drivers - WTF!! My OS is no longer supported... 10 years on, and the situation remains unchanged - PCs (including Macs) have their place, gaming, video editing, creating content, but an electronics workbench is not the place..

[@PeterWalkerHP16c]

WTF? My 7 YO Dell w/- SSD boots W10 in 15 secs. Rigol is a POS anyway. I have Macs and PCs amid my HP / Agilent / Fluke and Keithley gear. I keep my work bench clean, tidy.

[@henryrobinson9837]

i know your right ,but the automotive field is starting to use them,have you tested a PICO -scope, they are high, but a cheaper hantek pc-based scope is a good starter. not everyone is a high paid electronics engineer

[@Jonnyweareten]

Can you review the Hantek 6022BE. ? is it worth the 40 quid?

[@MrGayguru]

Crazy prices in video. Dave is just old-sсhool enemy of USB devises :)

[@DmitryMakhnachev]

Even nowdays it is cheaper to have display on board(bench oscilloscope) than to transfer huge data to laptop(pc-based). Of course for real time monitoring. The more bandwidth you've gotta have the less difference in cost between them all but the cost will be much of course... :) Do not be fooled by fake specs. Count, count and count... Fast memory on SoC to capture big bandwidth is extremely expensive compared to a small lcd on a board not speaking of CPU itself.

[@dafpnp]

Hi Dave, has your opinion changed on this topic over last 11 years since you made this video?

[@GioJonnhyK]

take a look on "Uni-T UT71E" EEVblog's video... and look also our comments. Dave is just an asshole bias-based everytime he has to test something that isn't "AMERIGAN PRODUCT" on the packaging.

[@duncanyoung8688]

but pc based ones where first bought out because they where cheap,but companys have tryed to make them better and more expensive so realy the original reason why thay where first made is forgoten,Ime buying one for £40 because i cant afford £500 for a proper one and if i could i still wouldnt spend that much money.They are a great cheap option.

[@CoolDudeClem]

The wost oscilloscopes I've ever seen are the ones on eBay that can be built from a kit. The bandwidth is TERRIBLE, only 3khz and I'm not joking! What can you do with just 3khz? Nothing!

[@jaeholee3816]

10 years passed...now about 100$ 60Mhz pc Scope we can get

[@RayIzzle100]

You need to think about the fact that some people might have a pc in their lab so that can't be a factor and you need to account for what they might be working on so explain what the pc is only good for and what you need a normal one for... also gonna say I watch a lot of your videos and enjoy them but you are too negative about stuff something that won't work for you might be perfect for someone else so you need to explain what that scope is gonna be good for or able to do...

[@jmac2050]

pc bias, all i needed was an soundcard, oscilloscopes GUI, probe.

[@Godzilla_Jesus]

This is pretty outdated. I think for the time, this information was great, but 10 years later, tech marches on. For $50 or so US, you get what you pay for. These USB scopes are great for old equipment (think 8 bit computers, radios, tube anything), but are useless for troubleshooting complicated/current gear. I just got a Hantek 6022BL. It's USB scope along with a logic analyzer. It was $40 bucks from China free shipping. Is this useful with 2 channels @ 20Mhz for anything? How good of a logic analyzer can it be with 16 channels at 40 bucks? Well, the answer is that I repair 8 bit computers (Atari, Commodore, Apple, etc) and this is a very good price point for what I'm using it for. Oddly, the limited bandwidth and "in the ballpark" LA actually work to my advantage. Why spend $1200 on a bench scope that has features that I don't need at this point? If a person gets more serious about electronics or does it for a living, a good bench scope is a must. But in 2019, the higher end USB scopes rival the bench scopes. SO, ask yourself "What am I using this for?" Let your answer be your guide.

I want to make a critical comment. Why dont you make some vlogs that teach electronics? I know that gadget reviews are cool as companies try to get you to review them... but, the substance of your vlogs should be to teach electronics, not just talk about electronics. Talking about electronics is getting boring. You are turning into a marketer of electronics... I guess marketing is what the 21st century is all about...

You are an annoying man, posting 4 messages when you could have posted one. You obviously haven't seen a modern bench oscilloscope- they weigh almost nothing and are really portable. Smaller than a laptop and hellofalot more useful than a crappy chinese pc based scope. Hey, if you can work with a cheap option for 40 quid, then the work you use it for isn't that important anyway. Sorry, but it's the truth!

Whats even more annoying is the 5 seconds I spent reading your whining when I could have spent it watching another one of his awesome blogs : /

You never have anything good to say in your videos.
