Siglent SDS800X HD 12 bit DSO's

[Antonio90]

you can't have everything...
I can't comment on the hdmi output because I don't need it at all.
You can't expect 50 ohm termination so quickly in this price range, regardless of the brand.
But the problem is easy to solve with the external terminators.
I have one from huber+suhner, and you don't notice any difference to an integrated one in the scope.

Oh, for sure. I don't think it has real competition in its price range. I'm just a bit salty at the 1000X-HD release price

Do you think this will help RIGOL get serious about quality?  I have a 924S with the LA accessory.  I'm thinking of getting this scope after it's been out for awhile, since it might meet its specs and advertised features reliably, unlike the RIGOL.

Nobody can predict the future, but Rigol's current business model appears the be releasing Alpha stage "Banana Ware" products, and putting no effort into support to keep their costs down. Siglent literally has teams of Beta testers, including some members on this website. As a Siglent fanboy / avid Rigol hater (my first scope was a Rigol), I would be 1000x more confident to purchase a release day Siglent scope vs. ANY scope from Rigol. That's just my biased opinion though. 😉

Hello!

According to teardown of SDS800X HD series, it has 2 AD converters one for ch1-2 and one for ch3-4. Just from AD perspective it would be possible to have 2GSa/s on 2 channels eg ch1 and ch3, also if all channels are on 1GSa/s would be possible. (as per specs. 2G /1ch active, 1G / 2ch active, 500M / 4ch active)
What do you think, is it a limitation of FPGA as can not handle so much data, or just positioning the device on market?

Cheers

That's just my biased opinion though. 😉

Yeah, that's my bias too.

It's just so nice to get an instrument out of the box and be able to literally turn it on and use it right away.  This is what happens with Siglent equipment.  Sure, I have to look into the docs for some esoteric setup item now and then but for the most part they are intuitive and, more important, basically bug free.

I know I've found what I thought were bugs with some of my Siglent stuff, but then I present that thought here and 10 people will explain to me why it's not actually a bug.  So, they are not 100% without a leaning curve, but it's usually a pretty easy climb.

Except when you buy a new SDS814X HD and try to use pinch & zoom gestures on the touch screen. Those did indeed not work on my new scope; they were interpreted as single-finger gestures. No idea how they managed to break this rather obvious functionality -- maybe a change of display type for the most recent batch of instruments built? Very convenient that tautech had just posted the new firmware which fixes this, the day before I received my scope...

But in general, I do agree. My DHO1074's firmware had many rough edges and glitches, more than one year after the scope's release. In contrast, the SDS814X HD feels like a polished product, refined over years of practical use. It's probably over-simplifying things a bit, but it seems that Siglent's priority is to ensure that a product works well, while Rigol focuses on making it look impressive. (Where tastes regarding the look do vary...)

Yes horrible. They fixed the bug in few days.... 
That is unacceptable !!
 

[2N3055]

Yep, as stated I was pleased that the new firmware was available just in time. Still a bit surprising how this slipped through QC in the first place -- must have been a last-minute change which was made with insufficient regression testing.

Truth is, fancy as they are, I personally find multi-touch gestures on screen are not so convenient.
After using this platform for few years now, I use screen to:

- select channel, math, before changing something.  (single touch).
- pan waveforms  left/right up/down. (single touch).
- move cursors or screen elements (single touch).
- move zoom selection (single touch).
- operate menus (single touch).
- Enter text (single touch).

Multi touch pinch moves to change timebase or vertical are bit uncomfortable for me. You need to either use both hands (better) or twist your hand and pinch/stretch fingers on one hand in position that is not natural to me.
I use knobs for that. That is why we have both.

So, for instance, I could have used that scope for months and never notice.

But it should work and it does now. As you said, probably some detail with touch controller driver parameters or something.

Agree, I find myself using single-touch much more often than multi-touch. But e.g. when I arrange multiple traces on the screen (vertical positions), I find it quite convenient to be able to also change their height (vertical amplification) without moving my hand away from the screen.

Yes, vertical pinch is usable sometimes.

I think it is useful for newbies. Makes the UI react just like a mobile phone. The newbie might not even know what knob does what, but touch and multi touch are instinctive.

In fact I think the touch screen interface is a major upgrade for newbies and casual users compared to the old sds1000 series. We teach how to use the scope at our local makerspace and this is much better.

I'm not against it. I'm OK if it is there.
But I'm sharing my experience of long term use.
Once you start getting used to how it works and make habits based on what is actually handy to you.

Mostly no multitouch use whatsoever, except like Ebastler said, occasional vertical pinch (in that position hand is at relatively comfortable angle). If I do horizontal it might be in FFT where you need to dive into menu, and then with two hands.

It is good to have options. I like both screen and knobs.

Anyone considering an 800 should hurry.
Batterfly currently seems to be the only dealer that still has a small quantity in stock and after that it will probably not go on until May...

[Martin72]

Hmmm.....
Welectron is always very fast and I don't currently have a scope....
No, I'm resisting the temptation.

[Martin72]

After 3 months of intensive testing, I sold it again.
I still think it's good, but no longer for the money, as something clearly better has come onto the market.
I was actually tempted to buy an 804 because I like to experience things for myself.
Otherwise I can borrow scopes from work, but I don't have an "emergency" at home at the moment.

[Martin72]

Oh what the heck, I've bought one now, you can get rid of it quite easily if.

Be prepared to be impressed to what has been crammed into these little DSO's.

Oh LOL, you didn't!!
You need therapy.. 

OTOH, that is killer little scope. You'll feel right at home.

[Martin72]

I'm already a bit curious...
If Welectron actually have it in stock, chances are good to get it delivered on Saturday - I like new toys at the weekend...
I'm going to get the SDS1104X-E from work to compare two generations.

[Martin72]

You need therapy..

Absolutely.
But I can make up the money by selling measuring equipment that I don't need.
I've already almost compensated for the upcoming SDS3034X HD (at some point...), which means I'm paying almost nothing extra.

It'll feel like tiny 2000xHd to you. Familiar out of the box.

We all have same problem..

No comparison at all, 800X HD is absolutely next level.

[Martin72]

I already know that, Rob.
When I saw the first pictures and it was immediately obvious that the 800s have the same UI as the other touchscreen scopes...
Then came Performa01 with his outstanding review....
I just want to clarify it again with the comparison.

That lasted less than 1/2 hour!  That makes me feel much better about my struggles to avoid buying things I want but really don't need.

[Martin72]

I like to make others feel good.

I was very, very curious and if my SDS3034X HD had arrived this week, my curiosity would have taken a different course.
Then I weighed up earlier how much my curiosity would cost me and came to the conclusion that it wouldn't cost me much, and with a bit of luck not at all.
And that tipped the scales.

Only 1 left now.
