Direct comparison aspects on Siglent SDS2000X Plus vs. SDS1000X HD

[ebastler]

The 7" SDS800X HD display is not wide enough to accomodate all the UI features of its bigger display brothers so MATH is assigned to the front panel and not in the dropdown menus, however the web UI permits just opening another channel with the OSD + allows us to dedicate MATH to the new channel.

Oh -- so even the regular small font is a bit larger (more pixels per character) on the 800X HD to improve readability. I had never realized; thanks for the screenshot comparison.

Btw: Since the HDMI out was one of my pro arguments towards the MSO5k back then....I really experience the remote LAN view of the Siglent as being very laggy being viewed side by side to the unit's display....is that normal (only tested the 1KXHD) ?

This brief video-clip gives an idea of what other users are obtaining on their Siglent live-web-input, at least back in marts 2024.

If anything will demonstrate the differences in frame rate between the scope display and remote web display, it will surely be roll mode. 

There's two things to consider: lag, and frame rate. For me, there was almost no lag when I had the SDS2504X+ connected via ethernet. However, the frame rate is only something like 15fps, which can feel like lag, but it is not.

[Uli Auer]

Here the whole web display is indeed very laggy - now tested on Chrome browser instead of Firefox - which is identical....

[ebastler]

There is another video on that same channel which demonstrates a more typical use case -- a signal with glitches, shown in regular sweep mode. Compared to a Rigol DHO's web interface, the frame rate that Siglent can display in the web broswer is not impressive.

I have been happy enough with my SDS800X HD's web interface. I have used it frequently to take screenshots, and sometimes to take a peek at a long-term measurement without leaving the sofa. But I would not use it as my main user interface at the bench (to get a larger screen without a dedicated video output).

[Uli Auer]

And yes, indeed also roll mode is not usable on the web gui...

YES. Exactly - that's why I'm rather getting the 10" screen (for "on the bench" use) with the S1000X HD....

[Uli Auer]

I think somebody should do a hardware hack for implementing a HDMI out on the Siglent scopes....;-))))

Dave?

Regardless of the frame rate, this video looks like an epileptic's nightmare. I prefer to work with well-synchronized signals, and then the frame rate is not so important.

[Uli Auer]

You know how to synchronize any faulty signal with intermitting drop-outs, glitches and and other artifacts....?

Wow...please tell me how to do that.....

[Martin72]

That's always too short for me personally.
I can only understand/compare something if I know the conditions.

In 2024, oscilloscopes can synchronize not only on the edges. Just read the user manual and you will discover many new synchronization options. Also, the zone trigger and holdoff options can work wonders for synchronization

I can see how this might seem daunting when previous experience was limited to a now obsolete scope without the many triggering options most modern scopes provide.

No longer are we happy with just stable triggering to provide a decipherable display so the multitude of triggering options that provide the ability to capture almost anything.

It's one thing to drive a scope to get stable triggering for repetitive signals and another to master the extensive trigger suite !

Comparing what the display provides vs Web display shows is self defeating, use one or the other and the absolute power of the triggers available.
This power is in your hands....... combine it with Single shot and Search for a new level of understanding of what a modern DSO can deliver.

What will frequency modulation or PWM look like?
 
7" is not enough for a display overloaded with information.
Super Phosphorus has faded into the background...

The subjects of this thread have 10" displays.

As long as the grid division is the same, the display of the signal is also the same, regardless of whether it is 5, 7, 10, 15, 20 or 30 inches.

Super Phosphorus has faded into the background...

Has nothing to do with it.

[TomKatt]

Isn’t the resolution the same also?  So same display, just slightly larger?

[tautech]

Which models ?

The subject of this thread is the 10" models, SDS2000X Plus and SDS1000X HD which have the same spec display:
10.1'' TFT LCD with capacitive touch screen(1024*600)

[Uli Auer]

Somewhere in this thread there were some votes for the new 800HD series - these are 7"
I think that's what TomKatt and artur are referring to

[Uli Auer]

I don't understand what super sophisticated triggering functions have to do with the discussed problem of the laggy LAN remote view?
The video posted by ebastler was simply showing exactly that behaviour - and proofing that the Rigol approach with the HDMI out - showing 1:1 (!) the same picture as the scope display is much better and more adult - of course just for THAT application of viewing a larger image without any loss of information ! And leaving the advantages of mouse and keyboard control out of the equation....
Of course implementing a real graphics board type HDMI out that also could provide a better resolution on larger external displays would be even betterrer, as Dave would say it....but that again would cost more I'd guess....

[Uli Auer]

Again: What's "too short" in my statement? If roll mode ain't roll on the remote screen I don't get the point....

[Mahagam]

The HDMI cable is pretty short, but a LAN connection usually gives you WiFi and internet, so you can easily and simply show an image from your oscilloscope anywhere you want.

[Uli Auer]

The HDMI cable is pretty short, but a LAN connection usually gives you WiFi and internet, so you can easily and simply show an image from your oscilloscope anywhere you want.

That's true. But in general a very theoretical application. I mean how far away from your measurements object / your probed circuit do you need your image to be shown? Having your circuit at work and your scope image at your home office?
And again: What's your (then even super remote) image worth when it's not showing what's on your scope?
You wouldn't even notice THAT your scope is showing something different....Sure, for more static display content (but only for that) that's not an issue....

You're confusing frame rate and lag.

If you want a better scope with faster frame rate and better screen options, you have to pay for it. Take a look at the new Magnova oscilloscope.

Or if you have a 'house' budget, go look at the R&S MXO5 series.

[ebastler]

Regardless of the frame rate, this video looks like an epileptic's nightmare. I prefer to work with well-synchronized signals, and then the frame rate is not so important.

I agree that it is always preferred to get a stable view of the rare event of interest, and with the powerful triggering options in modern scopes you can achieve that most of the time.

But before you set things up properly, you first need to realize that some unexpected signal is occurring. For me, the "Oops -- what was that little glitch on the screen?" has been the turning point of many eventually successful debugging sessions, sometimes identifying faults in areas where I had not expected them at all.

For that early "discovery" phase, I want a screen with fast updates, i.e. reasonably high frame rates. That's why I would not consider the Siglent web interface as my main UI at the bench (and I don't think it was meant to be that).
