"Low cost" = $400 (Month's wage where I live)

I think after all these years a new budget scope shootout is warranted, see if the Rigol is still the king

Please, more comparing two or more circuit boards of the same brand, with your excellent and always clear explanations on the details of the components and their purposes and effects on the circuit boards... You are ONE OF THE RU-vid KING OF ELECTRONICS and always thankful for your great work.

love from Kenya bought sds1202x-e after watching your channel loved it

So much crowding at the lower end: A very nice thing to see! I'm also blown away by what's happening in the low-end of the spectrum and network analyzer market, especially the OWON XSA 1000 series. I got my butt kicked at work while trying to get a new system through EMC certification. Had multiple issues below 1 GHz that none of our prior systems had exhibited, and two nasty spikes between 5 and 6 GHz. We have never done in-house pre-scans before going to folks like TUV SUD for a dress-rehearsal pre-scan then a qualification scan. This time did THREE pre-scans before we were ready for our cert scan. For the cost of just ONE external pre-scan, we can equip a surprisingly decent in-house lab for 1 GHz and below, including an EMC-capable spectrum analyzer (the OWON), EMC software (form Tekbox), antennas (from Tekbox and others), LNAs (from MiniCircuits), and a set of near-field probes (Tekbox).

Please do another scope shoot out Dave, we need you to compare them! And perhaps Keysight will refresh their scopes soon, i hope? That would also be something nice to look forwards to.

So, you get what you pay for. Makes sense. Thanks Dave as always!

I've never heard the word standard deviation used so many times lol thanks for the video great job as always happy holidays

Dave, I'm so glad you took one for the team with that sticky magnetic shielding - I was just about to get a roll and stick it literally everywhere on everything I have 😂

400 for this scope is actually pretty good. Given scope prices today are 3-4 times higher at the least. It's all the scope you need for most electronics repairs..!!! Good video Dave.

All thumbs up Dave 👍. Great overview. Interesting to see the changes but I’m not sure they have saved that much on the BOM there to cover that saving. I’m guessing there is a cut in dealer margin as well as often entry level products expect the dealer to take the hit as well on margin to bring people into the brand. The Rigol must have been getting enough traction over them to bring this to the table.

I was just about to buy a scope for the first time in my life, and I was going to go with the 1054z. Seeing this though, and looking on the specs and through the manual, I'm pulling the trigger on buying this one instead. It's 100 MHz over the 1054z's 50. I also like the way it's built in serial analyzer functions work compared to the 1054z. Being a newer unit means it's likely to have the firmware updated for longer than the now long in the tooth 1054Z.

The IC in MSOP above the OPA4872 is LMH6551

Relay has a big coil, the shielding on top shields some of the EM fields, but not magnetic fields. I suspect they put the mu metal on top to prevent magnetic pickup of the relay coil, which can then potentially couple into the ground/power supply lines. Origin of the magnetic field is probably from the power supply as you mentioned.

Got a rigol 1104, that I bough just recently for £400 and I’m pretty happy with it. By now all software bugs are ironed out and all features unlocked

Would be interesting to see if the new X's come out with that optimised power supply from the U.

I just bought the 1104x-e a couple months ago. Saw this video pop up and thought "man, please tell me they didn't come out with a cheaper UPGRADE!?" Whew, thanks for the teardown. Still happy with my purchase.

The extra $50 could be worth it to get 100MHz out of the box vs. having to get the code to enable it on the 1054. It will be interesting to see how the two scopes compare in features. A lot of features in the 1054 require codes to enable them. If many (or all) of the code enabled features of the 1054 are included in the Siglent without needing to pay extra for them it could be serious competition for the Rigol. Looking forward to the video where Dave turns on this puppy. :)

Bought the Rigol a few months before this video dropped. Sure the Siglent has a bigger screen but honestly, I prefer the 'encrusted with buttons' look of the Rigol. It's much more impressive looking. Which is really all that matters. I am kidding, but seriously, I much prefer buttons instead of trying to remember which menu to click on or hunt through touch interfaces. The 'Measure' button is always in the same place on the 1054Z. When I outgrow it, it will be demoted to Lissajous duty for my home studio.

Thanks

Cool stuff..I am learning alot hehe..thanks a bunch

It’s funny that you mention rating videos at the end. RU-vid has started doing that again, but it’ll appear randomly in my feed. As I’m scrolling, it’ll prompt me to give a rating out of 5 stars to a video I’ve previously watched

I am thinking the magnetic shields on top of the relays is to address radiated emission levels well above the bandwidth of the scope. I have used stick-on ferrite shields on ICs to bring products into CISPR radiated emissions compliance with this method. BTW, first time watch on your channel. Excellent job mate!

Perhaps the magnetic shield isn't to prevent interference from getting in, but rather getting out? Try switching the range to make the relay activate and see if it couples to other channels with and without the magnetic shield.

Would love a shootout between this, rigol, and other options. Thinking about getting a scope soon.

Just a random thought... Could it be the distance between relays and power supply that makes a difference and begs for magnetic shielding? What will happen if you assemble the scope fully without magnetic shield and run the same test?

They now use the same simple "Calibrated" sticker on the SDS 1104X-E as well (mine is almost 2 years old).

Interesting scope. Honestly, a 100MHz is a very good place for a modern scope to be fair. The Magnetic shielding in the channels seems rather tiny to be fair. Maybe they just had issues with RF bouncing around in the can and stuffed in an absorber to handle that. Could stuff in a sine wave and do an FFT and see if the noise floor changes. Or if any peaks and such disappear. If only the scope had a trigg in.... I don't like offering a channel for just a simple trigger. Also, were sitting thinking, "I would really like to watch a scope teardown from Dave..." And were going to head over to the channel to look for one that I haven't watched 3 times already... Guess I were lucky.

The mag shield would be to keep relay transients from displaying a glitch. Would not do anything if the relay were operating.

I would love to see a comparison to the classic 1054z

Are there any problems with the membrane buttons under the screen in the new version? I don't know how many such cases there are, but in my version of the E, the rectangular buttons under the screen made various bouncing sounds when pressed. I mean the sixth rectangular button (the one that acts as a RETURN). It seems to me that when clicked, this button makes a sound, similar to the buttons on a video game gamepad, while others are practically silent. Has anything similar happened at your case?

I got the 1202X-S. It's okay. If you don't use logical analyzer and you want a function gen, then it's great for that.

PGA in the older front end was an AD8370, not AD8350. Not a huge price difference, but I figured I'd mention it for the record.

didnt the rigol ds1054z had more math functions? i missed some on the 1104x-e

External magnetic fields can result in depression or elevation of the pull-in and drop out voltage of the affected relay, possibly causing them to fall outside their specification.

Dave's "get off my lawn" moment: asking whatever happened to video ratings. A change that was made back in 2009.

Does it have the "zoomout" feature on the single event trigger mode?

I have the 1104X-E after your review Dave, fantastic scope!

Rigol 1054Z shootout please!

Good rubish for aficionados 👍

I own a siglent 200MHz and have for 2 years. It works great.

I chose to get the GW Instek GDS-1054b for about $100 less. I like that it has dedicated controls for each channel, and you can hide the menus to use more of the screen for the waveforms.

could the magnetic shield be for some PSU noise issue at 120V/60? hard to see how it would help a lot but hard to see why else it was there

Dave, are the electrons going to fall out if you put the components at 45 degrees (6:45)?

On the off chance the weird transition at 16:48 was intentional and not an encoding error or something: I liked it!

Oh no! I've got to say it......... "that's not a knife"

I actually bought this as my first scope about 2 weeks ago! It works really well for my beginner-level applications, it's easy to use and quite capable if you don't really need high bandwidths all the time. My only problem with it so far were occasional hangs at boot, where you need to restart it for it to start up fully

I think the performance for the money is incredibly but I just cannot get over the build quality. How can they design such amazing electronics and still build wobbly knobs!

Could it be that the relais are bistable and the magnetic shielding protects them from being accidentally switched by magnetic fields from the surrounding while the relais are not engaged?

So, if we look away from the price on those two. Which is the best one?

Maybe the tape on the relays contacted the top cover for heat dissipation or prevent vibration? Magnetic attraction?

New modern shootout. Yes please, and thank you.

14:50 So it looks like the cut-down/redesigned one-way front-end in the SDS1104X-U has better quality signal quality than the other two? The component savings went into a super-expensive mux chip?

8:44 What's up with U44? Upper right corner. Is it chipped?

What is the input topology that would require a high-speed multiplexer on each channel?

Interesting to see the RA4 and RA8 on the lower cost version to be at an angle and not 100% horizontal/vertical. Isn't that more difficult to manufacture? I mean the part between 14:15 and 15:00

Wonder if the magnetic shield is there to prevent the relay's own coil 'glitching' its own channel or the one next to it? Those jumper links on the PSU are a footprint for a switch. Nice enough 'scope* but I think I'll probably save up a little longer for the X version. It's amazing what you get for the money now, my first 'scope was a single channel Cossor of a few MHz bandwidth and felt like was built on the chassis of a WW2 Russian armoured fighting vehicle. I had bugger all idea how to use it. Kids these days...

Companies are no longer allowed to use stickers to void warrantees here in the US. You’re allowed to open the product to look inside. Modifying the product is still a no no for maintaining the warrantee, of course.

TI's digikey pricing is super high on TI's website you can get that for less than $5 and I am sure if they are buying tens of thousands they are getting even better volume pricing.

Such a product engineering is actually quite complex. For once, what would be the specs of the new machine so that we can build it cheaper but GUARANTEE the match for the spec. Thats the hard part - to make the product working as advertised. So simplifying the feature set while still remaining useful. Pretty clever thinking there.

100 Mhz scopes are good to examine signals up to 20 mhz with good fidelity. Daiyve should do a video on scopes capable of dealing with today's gigahertz electronics.

"Floating head Dave" has improved.

Standard deviation of the standard deviation is absolutely a thing, but it is more about measuring the consistancy of that standard deviation...

"Let's void the warrantee on that bad boy"

Please do a comparison video on FFT in SDS1104X-U to SDS1202X-E

Currently looking at this, the X-E, and the rigol 1054z. Would you still hold the rigol as the best entry level?

Would like to see a video on if your recommendation has changed from the Rigol 1054z.

But Dave you should have put the psu in the assembled position to see any difference in the noise figure. Otherwise the psu magnetics are too far away. Anyways this scope is relatively unimpressive compared to the -E version.

Did Dave do full review of Siglent SDS1104X-E ? I searched but can't find.

The prices are really good these days. In 2014, I got crappy Hantek MSO5062D (2 channel 60MHz with small 800x480 LCD and crappy slow and horrible interface, + 16 digital inputs; 1Gsps; 1Mpts, no networking) for 520$. Sure, it sounds on paper similar, but Siglent new UI is so much nicer and faster in general, has more functions, better maths and statistics, more wafeforms per second, better triggers, better noise, etc. I should probably went with Rigol DS1054Z , instead of Hantek MSO5062D, but well, I tought it will be decent.

About rating videos, I occasionally get asked (by the RU-vid) to rate a video, watched a Big Clive vid the other day and about a day later got the rate this vid question from RU-vid. Not sure how it works but still a thing.

Hi, I have to buy an oscilloscope and have seen "50000" videos! I have such a confusion in my head that I can't decide which one to buy ... I ask you: Regarding the price range of 800 Euros (more or less ..), which oscilloscope do you recommend? GW, Siglent, Rigol, Rohde & Schwarz, or other .. can you give me your opinion? Thank you.

I will be in the market in the next 2-3 months depending on this question.... this or the rigol 1054z?

When r u gonna do the DSOX1204G from Keysight?

All those variable resistors look to be in a suspiciously similar position for something "calibrated" :p

i think the shielding for the relays is for when the relays are active and injecting signal into other channels

Dave, I request you to do a detailed Teardown with the newly released 12 Bit Owon XDS series!

Isn't there going to be some issue with the length of the waveform, and the stdev being "blind" to frequencies that are slow on the scale of a given waveform? Not just eliminating DC but all frequencies below a threshold too?

Probably you see in the FFT some spurs without the magnetic shielding.

what should we do if an oscilloscope is not fully isolated from power supply. I have a siglent function generator and an oscilloscope. and the problem is that the earth of these device are connected to each other no matter what. Do you have any solution?

I a,ways thought of silent as a high end brand that was beyond my budget, hell I gave almost $400 for the 1054z.

Me with my Tektronix 2246 100MHz 4ch scope, looking at this 🤯!! Maybe time to upgrade 🤔

Dear Sir, I have got Siglent SDS_1104X-E. Can it be hacked to 200MHz?

What is the white stuff on top of the caps at minute 18:27?

It is a nice budget scope. But is it better than the Rigol ?

sweet info... do you have a siglent Oscope modbus video? like trouble shooting IOT arduino modbus rtu rs485. 🤔 thank you

How to save in CSV file with reduced sample size? Every time when I save , I get about 380MB file with 14 milion lines which of course can not be loaded with excel

Was that really magnetic shielding tape, or is it thermal transfer tape to help transfer heat from the relay to the case (relay coil in enclosed box may make it heat and cause more front-end drift)

The Rigol DS1054Z be like: Finally a worthy opponent!

What are the "Trimmer Pots" for in the Frontend ? And how do you set them? Is there anybody who can qualify that for me, I can not seem to find much about it... Edit: O.K I heared Dave say: "to tweak your response.." that gives me something to search with..

19:20 Power supply, bottom left: might be a 110 - 230 selection.

AC in was probably on the board in its last application

Is it worth purchasing just to save the $100, or is the more expensive model worth the difference. After the teardown, I tend to think the latter. Thank you.

Sadly no Bodeplot function supported. I love that function in combination with my siglent AWG. This is something you seldom see on budget DSO's.

I would love to see a shootout in terms of automation via SCPI ... I do this a lot and its an area the DS1054 lets me down :( ... If the Siglent's have better SCPI comms it might be worth a change

The price difference here in Europe is a bit too small, the SDS1104X-E is 498 Euros while the SDS1104X-U is 417 Euros, thats a delta of 81 Euros. I dont know if this is worth it..

Those "shields" could be sound / vibration dampening.

I'm not going to remember my magnetics in detail at this hour, but I'm thinking that the magnetic shield may be only relevant when the case is completely closed. That's when the switching power supply is going to be closest to that relay coil. My thought is that it may be inducing a voltage in the coil that somehow backfeeds through the coil's transistors into the main circuit.

I want something 200mhz. How much is the 200mhz upgrade on the other model?

Hey 👋 i just bought the Siglent SDS1104X-E and i just now learned that you can hack it to be 200mhz!! How can I do that???
