EEVblog #1355 - NEW Siglent SDS1104X-U $399 4CH Oscilloscope Teardown

Teardown of the new $399 Siglent SDS_1104X-U Four Channel oscilloscope.
A cheaper alternative to the SDS1104X-E
And what's all this magnetic shielding stuff anyhow?

"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

[dreamcat]

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.

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

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 YOUTUBE KING OF ELECTRONICS and always thankful for your great work.

[matiastripaldi]

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

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).

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

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

[super_slo]

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.

[MatthewWellings]

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

[melgross]

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.

The IC in MSOP above the OPA4872 is LMH6551

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.

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

[NullStaticVoid]

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.

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

[gryzman]

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

[PanheadEL]

New modern shootout. Yes please, and thank you.

[NotApplicable]

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