Thanks for doing this. As a huge critic, that's my biggest compliment. I'm sick of reviews on products that cost so much that only a tiny portion of viewers will ever see them, especially people who work in the field at real companies. Once in a while it's fun to see that stuff. But, even though you claim no sponsorship because of your otherwise excellent rules, you take free gear. You can't lie about that. So, well let's see, play with a free $10K toy or a $500 tool people can actually use? No surprises, Dave plays with the cool stuff. Fair enough, I would too. But it's nice to see you ballance things out.
Just updated mine to the 6.1.35r2 firmware - finally finally fixed the Auto SetUp bug that has been plaguing me since day one (scope would brick if you used it - even power off didn't work).. I also no longer see the double trace with the PE effect Dave was showing.
I'm a med student and i spend most of the day watching your videos. i'm addicted. I can only dream of having one, crappy oscilloscope and when i watch your videos (especially mailbag...) my jealousy gland swell and turns hyperactive. love your videos... keep up the good work. thank you.
The "NAND JTAG" jumper likely sets the boot source for the Zynq. One way boots off the local NAND flash, the other waits for programming over JTAG. I'd imagine it's probably got a pull up/down to default to booting from the NAND when not strapped.
Yep. Lack of which forced me to purchase a RIgol DS1054Z instead of the Siglent 1202X-E just last week. Happily, I wanted just long enough to get the new low price. So I'm happy, but would have loved this one for $170 more as well.
Nothing strange, that is the usual what you get when you buy extra things from the manufacturer. If you want to try, buy from ebay, Amazon or Bang good. If you want to know it works, pay extra for that.
Zynq-7000 series FPGAs use separate memory for the Processing System (2xCortex A9) and the Logic System. They can get away with a single RAM chip for the processor.
So there is a very easy hack to enable 200Mhz, and the other options as well. (eevblog forums explain it well,) The reason for the 3 memory chips is fairly simple -- the two 128MByte on the right are dedicated sample memory -- connected to the fpga side of things. One chip for each pair of channels. (Keeping them on seperate channels so that the bandwidth is sufficient.) The third on the left is a 256MByte chip for the 2 ARM CPUs. Runs linux, and the scope app on top. Aside from the lack of 50Ohm input impedance option, this is a very decent entry level scope.
6:55 Assuming they're not fakes (a la Rulycon or Rukycon), it's somewhat comforting to see Rubycons in there, even though they're not a full complement.
I tried this with the SDS 1202X-E.. Same thing, but only if I use a metal object to hit the connector. When there are two waveforms, and you move the position knob, it removes the extra waveform and leaves only one on the screen. So i'd say it's a bug.
I see it mentions 1GSa/s in dual channel and 500MSa/s in Quad so it means that it has two ADC's one for each group of two channels ? This will be a big difference compared to Rigol that has 250MSa/s in Quad channel mode. Just looked again at the part where you open the scope and yes it seems there are two ADC's so it is superior to RIGOL and worth a bit of extra for this.
Yes, also if you check Siglent's website for SDS1104X-E & SDS1204X-E specifications, it says they have 2x 1GSa ADCs which makes 500Msps/ch (for each of 4 channels). Also have 2x 14Ms depth, which also makes 7Msps depth for each of the 4 channels. www.siglent.eu/sds1104x-e.html
This is what the guide says: " The four channel series has two 1 GSa/s ADC chips (channel 1 and 2 share one, channel 3 and 4 share another), so that each channel can achieve sample rates up to 500 MSa/and work on bandwidths of 200 MHz when all channels are enabled." So yes in order to have two signals samples at 1Gsps you should use channels 1 and 3 or 2 and 4. I haven't tried cause I'm still thinking whether to buy sds1104x-e or Rigol ds1054Z.
Well the basic decode is included yes, but both the AWG and the MSO hardware extras require software unlocks as well, so those are worthwhile hacks of course.
I tried to think up why multiple waveforms were displayed when tapping the BNC. I think the signal is being displayed in different zoom scales at the same time. Failure to clear the screen before zooming out and reprinting the waveform would be my guess. Take a look at how similar the waveforms appear in the horizontal plane. I think we're looking at the same wave with different zoom levels with slightly different horizontal offset and resolution.
Hi Dave, I'm really interested in seeing a comparison between the different low end scopes. I have a really old and low res USB scope (from Parallax Inc.) but I'm seriously thinking of getting one of these four channel low end scopes. Keep up the good work!
During one of the 'two-shots', the second shot seemed to go from absolute left to absolute right. So I think we are seeing oneshots that lasted two frames without them being properly rescaled to fit a single frame.
I bought a 1202. It is worth the money, but meh. Great scope, but wish the adjust knob wasn't used for menus. It feels like mush. Had issues with the decoder rs-232. SPI works. Get a USB logic analyzer instead of relying on scope for decode. Function generator actually works really nice, but setting frequency with adjustment knob sucks. Adjustment knob in general sucks. @10:20, the unpopulated part is a memory provision. The Zynq FGPA fabric gets programmed from the internal ARM processors. The Zynq is a bit different in that the processors boot first and program the fabric.
@@lukasbruderlin2723 Most USB LA's have better UI and are easier to work with than the scope based stuff. I'm not limited by scope memory when recording with a USB device. Usually they are using the computer's memory. Searching for things is easier when you need to type characters and several hex values. Scope based LA is still handy when you need to see if a glitch is occurring because of a power supply issue, or maybe a stray signal tickling a reset or BoD, or you need to view analog signals and the digital data they output. Tools for jobs.
+rocketman221projects -- Does it take more pressure for them to vent in that case? Do they still vent upward (which helps avoid the fluid from pooling on the PCB), or does it then vent to one side, potentially damaging other components?
I don't know how much pressure was inside them. The JB weld split apart and they vented out the top like normal. I made a video of it several years ago. One cap had JB weld over the vent and one had JB weld with a sheet metal over it. ruclips.net/video/ZaczI5xQk5k/видео.html
7:20 Some of these caps are Rubycons (looks like it's YXG series), which is great, but the 470uF 35V at C43 looks like another Lelon. The one further back adjacent to it might also be a Lelon - it's not a Rubycon because the vent pattern isn't right. We can only hope that Siglent put thought into which locations could survive being Lelons and it wasn't just random.
You seem to have the ear of some of the manufactures, I have a Owon sds7102s with the battery. Crappy scope but I needed the portability of the battery pack. Now I could a hand held but they lack the features. See if you can bend the ear just a little and get some "good" scopes with battery pack
Because there's no engagement made from Author > Viewer, and honestly, another Sig scope video? .... I personally enjoy the mailbag only and that's about it.
He has basically been phoning it in for the past few years. Too bad, I miss the old videos, a lot more informative and a lot less product wanking and/or slamming. There are a lot more channels out there now that do what he used to do, so that is nice.
I think that no one cares.. This teardowns of low end scopes are kind of pointless and boring. The hardware is almost fine for all of this units, but the software is almost totally crappy. It seems this teardowns are just a kind of marketing wank: "Just look at your beatifull hardware" But its the Software that's the key to a good Scope. If have seen and played with a few cheap scopes from Siglent and Uni-T, and their firmware were totally crap... Bugs, Strange menus, strange behaviour,...
Awesome, Dave! I have the Rigol 1054z but I haven't hacked it yet. I moved soon after I got it so I've been too busy with other things. Something I'm thinking about: at the start of booting there's "ECC disabled" and then "bad CRC"... I'm curious which one is the cause and which is the effect. Without really knowing more and diving into it I can't tell. With software it's entirely possible for the effect to be shown before the cause, it just depends on how those parts were written.
Should I buy one of these cheaper ones (SDS1104X-E or DS1054Z) + separate fuctiongen or scope with inbuild gen and pay +300€? any suggestion what benefits these options have? or link to forum is ok if this has been there some where...
10:10 - why are some of the lines below the central chip S shaped several times? Is this to lengthen the signal path so it will not be out of sync with another path that is a bit longer?
Correct, it's signal length matching. Rule of thumb is signals travel 15cm per nanosecond on a PCB, and that matters on today's high speed memory stuff.
I happily used a Tektronix 350MHz oscillocope where I could make a single shot and get 10M samples. Then I could zoom in and out to look at the whole capture. A miniature of the whole capture could be seen so I knew where I was zoomed in. Is there a similar feature on this Siglent?
Yes, so at 14Msamples you can be around 1-5ms/div and still get the full 1GS/s resolution when you zoom in. Any smaller horizontal timebase and you get history frames at the full resolution. If the resolution isn't as important as the history frames you can turn down the memory depth and get more history.
I mean, the video has been improperly resized during the process, with a pixel aspect different than a square (anamorphic). it is more noticeable on rounded silhouettes...
I also noticed this right away. The compression is very noticeable for example right at 7:50 - lots of detail lost. But hey, no biggie. We're all just too spoiled by your normally excellent content ;)
Yep, sorry, my new windows 10 machine with a new version of Handbrake wasn't compatible with my old handbrake scripts, so I had to convert manually using the GUI. I think I had Anamorphic turned on. Didn't see it on my preview window.
At 00:06, the audiol level go down, then, theres thes voice saying "I see You", looks like that theres something wrong with the counter at this point! Somebody confirm that please...
Is it as loud/noisy as the DS1054Z? Most of the times I've find my self using my TDS220 rather the DS1054Z. Better buy an old used tektronix rather new DSOs.
Does anyone know if you can save all of the waveform points to a file for viewing on a pc? I tried saving the waveform but it only gives me the part that's visible on the screen. I want everything that was acquired during the trigger.
But then again, I'm happy with 200 MHz, two channels, serial decode and no more extras that could be purchased. Since I do have a Zeroplus logic analyzer and a Tektronix arb gen, there is really nothing I am missing out on.
Hi Dave, question for you, is this still a good buy for 499, or is there any other model with 4 channels and 100 Mhz? I like the 4 ch but also considering a 2 ch 200 Mhz. thanks.
Pretty sure that's where you connect the optional logic analyzer. Using existing high volume consumer connectors keeps the price down (and keeps people at buying new scopes after they fried the internals after connecting a TV to it ;) ).
What ever happened? I remember the first videos Dave used publish that taught electronics, but now its tear downs, and mail bags. Everyone and his brother is doing that. I used to fund Dave; in fact it was he who re-launched me into electronics. I loved his tutorials about op-amps and power supplies. I was so impressed I designed (with some help) a battery powered lab supply with reverse polarity protection, single push button on/off, auto turn off (battery protection),with all the bells and whistles on a 50x50mm PCB. I do like his rants about things like solar roadways etc. I would re-fund him if he went back to his roots. Come back Dave what happened?
I get that you don't like teardowns and mailbags, but please remember that others do. Look at my last say 20 videos (ignoring the old Keysight tour videos) - 2 scope teardowns - A series of 3 videos on ceramic capacitor cracking (very interesting technically) - A bunch of interesting teardowns including vinatge - BGA PCB fanout design - Digital design tutorial - A debunking video - A microcontroller coding video - Tutorial on how to find gear on ebay - Reviewing low cost PSU's and LCR tester - A couple of EEVacademy videos. A decent mix of videos if I do say so myself. How many mailbags? ONE or TWO in the last 20-30 videos? How many since video #1000? Go and count them. As for teardowns, perhaps you forget that my channel has grown based on teardowns, and I used to have a weekly segment called Teardown Tuesday they were/are so popular. If you are going to complain about my choice of videos, fine, but at least go an actually look at what I've been producing instead of just what you "feel" like I've been producing.
Dave, don’t get you panties in a bunch, why such umbrage? You missed my point entirely. It’s not that I don’t like the any of your videos that would not be true. It would also be untrue to say I don’t like mailbag, or teardowns, or that I consider you a Lilliputian jobbernowl. What would be true is that I would like to see more build projects. It is in those projects that you become an educator, teaching thousands about the wonders of electronics, as you did me. I consider you a rapscallion and sagacious person, sometimes funny sometime jejune, but always Dave. Don’t be a jobbernowl, bring back the build projects.
well, depends on the application. On the 50hz-60hz loading cap, a Lelon is probably fine. On the high frequency side, you Need low esr hq caps. That's important.
Thanks for doing this. As a huge critic, that's my biggest compliment. I'm sick of reviews on products that cost so much that only a tiny portion of viewers will ever see them, especially people who work in the field at real companies.

@EEVblog Can you tell us the model of the USB adapter? Looks like a TL-WN725N, which you can get for $9 on Newegg in the US.

How are the ADCs connected? If I use two channels, do I need to use 1 & 3 to be able to sample at 1 GHz?
This is what the guide says: "

This might be the modt anticipated video you'd do this year :D
The power supply looks like it has PFC in it.
12:43 DRV_PRODUCT_PIKACHU :D
Is this an easter egg??
There's also a segfault not far above that
Would love to see the hookup and config/prep that produces what we see @12:39
Rigol needs to add wifi dongle support, neat feature.
Beats it with a screwdriver.
Wonders why it bugs out.
Darnit, the choice was so easy before!!
Looks like a handy bit of kit dave, Rubycon capacitors Hmmmmm yum :)
At 00:06, the audiol level go down, then, theres thes voice saying "I see You", looks like that theres something wrong with the counter at this point! Somebody confirm that please...
Is this comparable with Rigol's DHO800/900?
Is it as loud/noisy as the DS1054Z?
Most of the times I've find my self using my TDS220 rather the DS1054Z.
Better buy an old used tektronix rather new DSOs.
on serial dump : BAD CRC, Bad Block, Segmentation Fault. Woohooo you got a faulty memory somewhere ? :)
Thinking about getting this scope, it looks nice. Wondering if the empy memory chip U27 has any use (possible upgrade), why is it there at all?
What part number is that TO-220 pkg that you were poking around at on the edge of the power supply board?
Nevermind you answered it.
I know I can search, but, what fun is that... what is network capability for on a 'scope?
I'd be interested also
Allows full remote control of most functions over the network
It's Christmas 2018, how is the firmware for this today? The multi-capture bug looks like a screen erase issue when a bunch of triggers come in.
beer+nut+eevblog = Good day
I can hardly wait for your evaluation of this scope compared to the Rigol
where would that review be found?
Dave are you working on a shoot out or review of this model?
WHOOPS!! ALERT !! Another 4 channel scope WITHOUT INDEPENDENT CONTROLS for vertical channels. That's always a dealbreaker for the cognoscenti.
NeverTalkToCops1 why would it be an issue? Too much work to quickly press the channel button first?
Does anyone know if you can save all of the waveform points to a file for viewing on a pc? I tried saving the waveform but it only gives me the part that's visible on the screen. I want everything that was acquired during the trigger.
Hi Dave! I'm very interested on triggering problems on siglent, what about persistence setting?
I want one. I hope they fix that glitch though. If it is hackable to 200Mhz the sample rate is OK for one channel use isn't it?
why its so bad the quality of your microscope? bad compression?
I don't understand how tapping the ground can induce a signal (it's ground after all). I never tried that with a TDS (yet).
It’s not an electrical response, the mechanical vibration is coupled into the capacitors of the front end and generates a spurious signal.
Why not put more stable Capacitors on the input then?
Whats with the holes in the front panel ? Slots for overlays?
That was a quick video!
Aww. Just upgraded to the SDS1202X-E a few months back. Why are you doing this to me, Siglent?!
But then again, I'm happy with 200 MHz, two channels, serial decode and no more extras that could be purchased.
Since I do have a Zeroplus logic analyzer and a Tektronix arb gen, there is really nothing I am missing out on.
me too!
Well does it really needs the upgrade? Something Dave didn't really talk about
Yay, just in ti,e for Christmas:)
Hi Dave, question for you, is this still a good buy for 499, or is there any other model with 4 channels and 100 Mhz? I like the 4 ch but also considering a 2 ch 200 Mhz. thanks.
Google around. There is a way to change the software to get 200MHz out of this thing.
You can hack this to 200 Mhz or 70 Mhz if you like, just by entering a serial number. You can reverse to 100 Mhz at any time.
y they put toothpaste on it?
Is that a HDMI port on the front just next to the USB connector? that would be sweet if you could atach a monitor to it and get a much larger picture.
It's probably not video in/out considering "Sbus" marking underneath it, but still I have no idea what it is for.
Hard to tell from the video but the jack looks a lot like a HDMI connector
Pretty sure that's where you connect the optional logic analyzer. Using existing high volume consumer connectors keeps the price down (and keeps people at buying new scopes after they fried the internals after connecting a TV to it ;) ).
We will have to wait and see. I am planing on buying one as soon as I can
the only "SBUS" i remember was from Sun Microsystems, but they surely wouldn't use such an out dated bus on a new scope!
Can be this scope compared to Micsig?
One on order....
What ever happened? I remember the first videos Dave used publish that taught electronics, but now its tear downs, and mail bags. Everyone and his brother is doing that. I used to fund Dave; in fact it was he who re-launched me into electronics. I loved his tutorials about op-amps and power supplies. I was so impressed I designed (with some help) a battery powered lab supply with reverse polarity protection, single push button on/off, auto turn off (battery protection),with all the bells and whistles on a 50x50mm PCB. I do like his rants about things like solar roadways etc. I would re-fund him if he went back to his roots. Come back Dave what happened?
I get that you don't like teardowns and mailbags, but please remember that others do.
Look at my last say 20 videos (ignoring the old Keysight tour videos)
- 2 scope teardowns
- A series of 3 videos on ceramic capacitor cracking (very interesting technically)
- A bunch of interesting teardowns including vinatge
- BGA PCB fanout design
- Digital design tutorial
- A debunking video
- A microcontroller coding video
- Tutorial on how to find gear on ebay
- Reviewing low cost PSU's and LCR tester
- A couple of EEVacademy videos.
A decent mix of videos if I do say so myself.
How many mailbags? ONE or TWO in the last 20-30 videos? How many since video #1000? Go and count them.
As for teardowns, perhaps you forget that my channel has grown based on teardowns, and I used to have a weekly segment called Teardown Tuesday they were/are so popular.
If you are going to complain about my choice of videos, fine, but at least go an actually look at what I've been producing instead of just what you "feel" like I've been producing.
Dave, don’t get you panties in a bunch, why such umbrage? You missed my point entirely. It’s not that I don’t like the any of your videos that would not be true. It would also be untrue to say I don’t like mailbag, or teardowns, or that I consider you a Lilliputian jobbernowl.
What would be true is that I would like to see more build projects. It is in those projects that you become an educator, teaching thousands about the wonders of electronics, as you did me. I consider you a rapscallion and sagacious person, sometimes funny sometime jejune, but always Dave. Don’t be a jobbernowl, bring back the build projects.
Hi, does anyone know what frequency reference STD this scope uses ,
Thanks Dave
Just a regular cristal.
Ok thanks
69$ for a wifi dongle .....wow, just wow.
any updates on the hacks?
All options and bandwidth methods documented on EEVblog forum
Such a capacitor snob! Must everything be top shelf?
Yep, it must.
It is a weakness and it is good that he show it.
You have to decide whether it is significant or not.
yes. Also for a PSU it is somewhat like a running gag to see crappy caps inside.
well, depends on the application. On the 50hz-60hz loading cap, a Lelon is probably fine. On the high frequency side, you Need low esr hq caps. That's important.
Quality capacitors on the secondary can be the difference between a power supply lasting 2 years or 20. Yeah, it's worth pointing out.
Interesting.
Did they fix the bug at 16:00?
It looks like it. Firmware update 6.1.35r2 seems to have fixed mine (alone with a few other issues)
@@markrichards5630 Thanks Mark!
