Siglent SDS2000X Plus

[2N3055]

I agree with Dave. It is a horrible design with all the pastel colours and fake silver rings on the knobs. Looks more like a beautybox for a teenager girl (on a budget), than like a professional test equipment. 

If you don't like how it looks, well, then I recommend you should not call it out on a date or marry it...

YMMD

As I said, it´s a matter of personal taste, but....



For me, the R&S got the best design, then siglent, then keysight, then rigol, then micsig, then tek....

Until you've used one you will never know. 

The front panel design layout is better than SDS5kX with buttons better grouped that are less commonly used.
But a real shame it doesn't have the 3rd USB port like 5kX has. 

But Siglent have learnt from this and the SDS6kX Pro does better with 4 USB ports, 2 front, 2 rear but we won't see these models in the west for a while yet.

Disagree...

One for the mouse, the second for the stick, it´s enough.....

Power STB3, current probe, charge phone.......

.....external USB supply....

.....external USB supply....

I know.....I need use one sometimes just to take screenshots for you all here.

I love using the mouse with these new scopes but it hogs a USB port however with the 3 ports on 5kX it is not so much a problem.

[Martin72]

Got a three port usb hub here, will test it on the siglent, if it´s work as expected on pc´s.

[Elasia]

I use a 3.0 hub on it.. works fine, remember its already a linux computer inside, its anything with a dedicated embedded processor that has been specialized to watch out for, not anything running on generalized hardware

It works, isnt an eyesore, and no wasted space... i'd marry it

Although my favorite industrial designs tend to be R&S but they are big bucks usually

[Martin72]

Same here....

If I got the money ( I got it, but not all for this hobby thing), I´ll spend it for an R&S scope.
But I couldn´t, so I spend it for the second best....

Hi,

Yesterday my new sdg 1032, eh, 1062X arrived, today I wanted to measure the waveform update rate from my 2504X.
So I´ve connected the pass/fail/trigger out to the counter input.
Threshold setting to 1V.
Memdepth setting to minimum, feed in a 25Mhz signal and set the timebase for displaying one period.
And the counter counts....nothing.
Or something between 17...20Hz (when you disable measurings, it count´s nothing).
I wonder why it won´t function, this method I´ve used on my former rigol and it works exactly (500000Wfs....) like if you use a scope for.
Hmm...meanwhile I type this here, maybe 1V won´t fit.
Check that.
Edit:
That was it, setting to 1.5V and it works

[Martin72]

Done a few measures.

Normal mode, the maximum wfs/s was 18961 on 5ns/div., sequential mode 50607 on the same timebase.
Dot/vector makes no difference.
Wfms/s was unstable in sequential mode, so I did a break after some measurings.
According to the specs, the maximum wfs/s should be 120000 in normal and 480000 in sequential mode.
I won´t say a thing, if the real values were something between 100000/normal and 400000/seq. .
But this values, if I done it correct, are poor and it seems to be a bug to be fixed.

[maginnovision]

What about less than 5ns?

[Martin72]

You´re right, I´ve forgot the 2ns ( done the measure in such manner, that always one period of the signal fills the screen).

I was saying the same for a long time, nobody paid attention.  Tautech said the spec was done by "Design Engineers".  Yeah, the design engineers wanted 120,000wfm/s, then R&D came up with 10% of spec.  It is not only the count, if you look at the signal with a scope, you will find some odd dead time in between.  I suspect it is measurement time, then if you activate statistics, the dead time increases significantly. 

[Martin72]

Yeah, to get the maximum value I must deactivate any measures.
8bit/10bit plays a role too and switching from fast to slow acquisition, this thing do it´s business...
Nevertheless, in my opinion it´s too wide apart from the specs.
Done this as I said before with the rigol, it matches exactly the specs and more.
Also the trigger-signal from the rigol was so stable, that counter and scope measurings was equal.
So what´s going on with the siglent...
To be honest, that doesn´t worrying me in a matter, I would give it away.
But I find it remarkable enough to expect an official explanation for it.
Edit: Forwarded this to the siglent support.

[0xdeadbeef]

Didn't we discuss this before and point mode is needed for maximum speed?

[Martin72]

As I wrote it before, point/vector mode doesn´t take an effect - Maybe I´ve done something wrong, but this was the result.
Apart from this, i hope I got an answer/detailed explanation from siglent.

[tautech]

To all, see how the master measures WFPS here:
https://www.eevblog.com/forum/testgear/siglent-sds1000x-series-oscilloscopes/msg1142108/#msg1142108

He has posted many Siglent WFPS tables over the years on most models and all meet spec !

There are certain operating conditions required to match datasheet results and some little thought is required to understand why. 

[Martin72]

Hehe...

He should do this again with this model - As I said, maybe I did it not correctly, but missing the specs this way over is an indicator that something couldn´t be right.
And:
What´s the problem to describe in the specs under which circumstances these rates will be reached ?
So that everyone can measure it by.
As I wrote, rigol claims for the 5000 model update-rates up to 500000wfs/s and I could immediately proof this without any "tricks".

Notice his flag lately ?
Parked up on northern China waiting for this CV stuff to get under control in the EU....if it ever does.

Study the charts, it's all there.

Tricks ?  Optimal settings !

It is about knowing how to get the best from your instrument for the need at hand.
A very good example from another great post from rf-loop is here:
https://www.eevblog.com/forum/testgear/scope-wars/msg3121780/#msg3121780
Really really study it. 

[Martin72]

Another suggestion, show me how to do it. 
Or show measures and then explain how you did it.
Or let´s waiting together what the support "says"..

Maybe in a few days when more Plus models are in stock and after I get backorders away.

You have the scope so use clues from the charts for settings and IIRC use Dot mode.
