[@electronash]

+EEVblog - Is the list display possibly showing because it say Display ON (around 40:20 in the vid), even though the Decode mode is Off? I'm not speaking from experience at all here (it will be a long time before I could justify the price of a new 'scope. :p ), I'm just assuming it might be storing the history of the decode after the Decode mode itself is off, but you then have the choice of enabling the history display in the other decode menu? I've often wondered why they don't include realtime / hardware decoding for the common serial formats in ALL 'scopes in this price range these days? Surely it would be something simple enough for them to implement in an FPGA, and that would still include decoding for any part of the captured sample memory? That goes for things like the vector calcs too - it's something that you would think could be done on the FPGA / ASIC side so it doesn't slow down the update rate as much? The acquisition part of these scopes should be kept as separate as possible to the screen display side as well, so I'm not sure why the screen has so much influence over the update rate etc.? It looks like they try to do a bit too much in software these days, and rely on the processing power of the CPU alone to calculate and decode a lot of stuff that could possibly be better served by logic in an FPGA or ASIC? It would be interesting to know what actually goes into designing a modern 'scope, and what trade-offs they often have to make between sample depth, waveform update rate, screen update rate, hardware decoding, bandwidth, response time, UI stuff etc. It must be a nightmare to figure all of that out and test it thoroughly. lol

+TubiCal I purchased my first scope when I was 17 years old. I paid $750 (a lot of hard work) for it used. I still have it but never use it in favor my prized analog Tek scopes however, I have one DSO and use it more than I'd like to admit due to it's storage capability. Today, young people have an extreme advantage over their counterparts of 30 years ago. They have a world of instant information at their finger tips and very affordable, high tech test equipment available to them. Most of today's DSO's have features that did not exists 30 years ago and the few scopes that could come close, were only available in high tech labs. If only I would have had these options when I was younger.

[@mosfet500]

You need four channel scopes to decode SPI. (MOSI,MISO,SS,SCK). I wouldn't buy a two channel scope. The other thing is a that new scopes are going to get cheaper as chips improve. So, sure the Siglent looks great, and it is for the price, but watch what happens when the other guys incorporate new technology into their equipment. All this is good for us because we get the cutting edge cheaper and cheaper. I just bought the Keysight 34465a, goes down to 1uA scale - that's pA's I'm looking at. Great for uC low current testing.

I bought two of these. If you have a stand-alone logic analyzer, this is the way to go. Love it. I use a Saleae Logic analyzer (best working PC tools I've ever had) because I like having that connected to my PC anyways. My biggest issue with the Siglent is that the Intensity/Adjust knob is a bit cheap on how it works. I don't like needing to go thru menus for intensity, and that knob doesn't feel well with the menus either.

HI Dave, Would it be possible for you to do a video on Buying a second hand scope? as someone just starting to experiment with simple circuits i have no idea what all that marketing jargon means. What are the pitfalls for us noobs? what's too good to be true? That sort of thing, maybe go over several bits of different kit that a beginner might need and what to watch out for. Thanks for the vids, they've sparked my interest in electronics.

[@ethanpoole3443]

With these newer entry level digital storage oscilloscopes there is not a whole lot of savings to be found in older used oscilloscopes unless you are willing to settle for an analog oscilloscope. Buying an older digital oscilloscope will often mean sacrificing many very desirable features just to save a couple hours bored dollars. But the biggest pitfall for a beginner shopping for a new oscilloscope is buying too little bandwidth as people often mistake a "50 MHz" oscilloscope as meaning they will be able to make accurate measurements and see higher superimposed noise and glitches on the 47MHz waveform they are seeking to analyze -- also ensure that the sample rate is high enough (4x+) to reasonably begin to capture your intended waveform in a single shot (for example, a 1GS/sec oscilloscope will never be able to properly approximate a waveform greater than 250MHz, and to see actual noise or glitches at such frequencies will require even greater sampling rates).

[@EEVblog]

+Zero Ryoko I could do that. The question though is always what is your budget and your requirements. i.e. are you after the best analog bandwidth, the best bang-per-buck, 4 channels, what? At the low price end, there is probably little point going 2nd hand. But if you were looking at spending a few thousand, then there are some good 2nd hand options.

[@venteotl]

it is the trigger output, every bench oscilloscope has it, usually it is a bnc on the back .it outputs a signal every time the oscilloscope gets triggered, in this case the rigol is showing how many times the siglent triggers a signal in a second

It is VERY quiet much more quiet than the Rigol. Solid build, know a bit sensitive but acceptable. Also, do not like the measurement displays a they are not separated by their own box/framing. Rather just small text placed under waveform box.

So tempted by one of these. Around £350 for the siglent, rigol ds1054 is £370 or the ds2052 is around £600 (and outside my budget). Originally I was looking at the owon scopes but you vid on them put me right off. The four channels of the rigol is tempting but the screen and dpo swings me to the siglent. Decisions, decisions.

[@waqastabassam1428]

I know it's been a long time since your comment... which scope did you eventually decide on getting? I have the same issue with screen of the siglent vs the four channels of the rigol!

[@ragnor0k]

I bought the four channel Rigol. I would have liked the bigger screen. But I'm always telling the junior engineers at work to use more channels on their scope to view more and better under stand what is happening in complex systems. I get really frustrated when an engineer has a four channel scope at their disposal and only ever seem to use one channel!!!! grr! If I'm honest I think I made the right decision, For the money it's a very good scope. my only critisms are like Dave said the fan is very loud and measurements take up a lot of space. But on the flip side it is handy to have the measurement function so accessible. Oh and I wish it could remember the same settings every time i turn it one. Hope this helps

[@jensharbers6702]

I work in an Electronic lab for medicine devices. Most part of your scopes are 200Mhz (Well with proper Gs/sec), but we're mostly using 20Mhz at best. And for an entry level (I'm about to buy the 1202X-E also) or normal Hobby user this Siglent is fine. It has it's disadvantages, but remember, 380 Bucks for an good working oscilloscope. Yeah, you can easily go better (Pico scope 5000series, R&S RTM3004 with 10bit), but the prices are going up exponential. In my opinion the Siglent is a good "home and hobby" use scope. Also it is suitable for measurements for car sensors (crankshaft and camshaft position sensor signals, PWM's etc.).

What is the difference between the "EXT" and "EXT/5" -external trigger options in the menu? Also I've not found good information about the video trigger options, with respect to lines. "Line num" seems to trigger on a specific line inside a frame window (which is great btw) in a composite video signal. But I miss more comprehensive details about this feature, as many other features. It's a great scope with a very shallow manual.

[@stephenbarfield3211]

The EXT/5 setting attenuates the external (EXT) input signal by a factor of 5. Say the external trigger signal was 50 volts. It might overload the EXT input so EXT/5 would drop it back to 10 volts.

[@peteabc1]

I bought rigol 1054z based on some of your videos and I must thank you..still the best scope for hobbyist (like me). Only thing i'm missing is the 50ohm input switch. And the freq range goes well beyond 100MHz (of course the signal is attenuated). I can see FM stations in FFT view... (I know it should theoretically go to 500MHz and depends more on the analog aa input filters)

[@SirBunghole]

Maybe now Rigol will adjust their prices on the 200MHz down to something more reasonable.

Please give me idea about how do I make it work i.e. DAC operation atleast upto 10Mhz and upto 50Mhz ideally. Thanks in advance

Yeah. My experience with low end test equipment is the lack of decent firmware QA. Rigol is as low as I'll go for serious test equipment. They do a half way decent job of making sure their firmware works properly. Look at the bugs Dave found. They are obvious and easy to replicate. IMO companies like Siglent just don't take their firmware seriously.

How long do you think it will be before we get affordable scopes with more than an 8 bit AD? It seems DSO's are mainly aimed at the digital world. For us that do mostly audio work, 8 bits is to coarse for our needs. Is it really that much more expensive to use 12 or 14 bits (or more)?

[@ethanpoole3443]

+Samuele Disegna If you do a bit of a thought experiment one may realize that to determine the zero crossover points and estimate the amplitude will require at least 2 samples per half-cycle, or 4 samples per cycle/Hertz being sampled. Of course that is just to reproduce an estimate of the waveform, those 4 sample points will not render any detail with respect to higher frequency components superimposed on your waveform because there is no extra data available to capture those intermediate deviations.

[@gabiold]

2x to reproduce the frequency in sine wave. All waves are the sum of sine waves, so if you see a 200 MHz-looking wave on the screen which is "sharper than" a sine, then it contains higher frequency components than 200 MHz.

I had also discovered that the ground level reference of each channel would "jump up" ~20 MV when ANY vertical change was made to the other channel which showed a severe flaw in the design of this "ONE VERTICAL CONTROL SET BULLSHIT". Rigol stated they reported this bug for correction which has been over six months ago and STILL no FW revision change from the time this bug was reported. Evidently they are happy with this channel interaction being present and have not decided it was important enough to fix it....

hello friends, i would really appreciate some honest, professional advice. if any of you can help me it would be greatly appreciated! i have been producing electronic music for a long time and i have always been fascinated by looking at wave forms as i am making edits to sounds. ive used many software oscilloscopes but im not satisfied, the waves dont seem to "flow" like they do with these external units. i will only be using it to see waves im generating with various sound sources and nothing more. i know for me a software one is fine but its also a novelty thing... when it comes to sound i am a fully blown nerd! with that in mind, would it be safe to assume i only need to buy a cheap-ish one? what would be a reasonably priced oscilloscope for me? i would be prepared to pay up to $500 as i will most defiantly use it for life... but for this application if a cheap one is all i need then please let me know.!thank you!

Another advantage of CROs over DSOs: No goddamn firmware bugs ruining perfectly good hardware >:|

Can someone please tell me how to wire up th 3 wire digital volt meters, I know 1 black wire is for negative 1 red wire is forpower and 1blue wire is for signal. I need it to measure from 1 to 30 volts on my adjustable regulator but the wire for lighting up the display the red wire needs 3 -15v. I am at an impasse at the moment can anyone tell me of a video or some explanation. Please

The display will require its own dedicated power source at whatever voltage (or within a range of voltage) it's documentation specifies. Most likely the negative lead will be a common ground with whatever voltage you are trying to measure (as well as the negative for the meter's own power source) and the sense wire would then be the positive side of the voltage you are measuring. The backlighting can run off the same dedicated power supply that powers the meter itself provided the voltage is appropriate for both the meter and backlight. With a variable output supply the meter can not be reliably powered by the regulated output you are trying to measure, hence it will require a dedicated power source of its own. However, is your meter compatible with a 30V input? Some may require a resistor divider network to map higher voltages to a lower voltage (usually in 10x decades, as in map 0-30 to 0-3) and then simply move the decimal point to map the lower voltage to its higher voltage.

+Ethan Poole The input for the AC-DC converter with adjustable out put has to be between .5v - 39v And I am running a multitap transformer with 34, 27.5, 24, 20, 17.5, 15, 12 volt outputs plus the 0v. But this limits the ability to run the 3 wire digital display that requires 3 - 18 volts for the display power.

[@ethanpoole3443]

+gigabytex64 You just need to add a simple 5V (or 6,8,9,12 or 15, your choice) linear regulator, such as a 7805, off one of the lower voltage taps that powers your panel meter. Then let your AC-DC converter regulate your variable output and attach the sense wire to the converter's positive output. Is the 39V figure an AC voltage for the regulator's input (I am assuming so)? If so then your high tap at 34VAC is perfectly fine so long as your mains voltage is not too high, but if that were a rectified DC figure then the peak voltage of a rectified 34VAC tap will potentially exceed 48VDC (34x1.41) when the transformer is lightly loaded -- just something to be aware of when rectifying AC voltages. When using the AC-DC converter there is no real advantage to the multiple taps other than the one lower voltage tap for powering the panel meter. Multi-tap transformers are typically a way to optimize linear DC regulators by reducing power dissipation at lower voltages. Good luck!

[@gigabytex64]

+Ethan Poole Thanks, you are correct as the AC is 39 but my converted and regulated voltage is sitting on 35 volt DC. so it would be fine to place the sense wire on the regulated 35v and just run a separate tap rectify and regulate it for the negative and positive for the power on the meter !.

Sexiest oscilloscope I've seen!

[@MauriatOttolink]

virgen virgen. Well the superb device is so light that if you dropped it on your foot, you wouldn't be shagged nor would the 1202.

[@bulwinkle]

Pink and yellow, looks like it's been designed for the female engineers amongst us.

[@Gowintech]

Dave,could you speak it a bit slow:)

[@user-lp2op9uu1w]

Wow, I like it! Even a poor student like me can afford it!

[@8bits59]

Do you ever take off the screen protector? XD

[@Bradman175]

I dont

[@neptunevibe]

27:06 Of course is perfect mate. Is Chinese technology not those craps made by americans. Chinese tech and engineering with the high quality production and materials from China! I'm glad you love it!

[@aneeshprasobhan]

hmm, isn't keysight and the german Rohde&Schwarz miles better than these Chinese scopes ?
