Siglent SDS2000X Plus

[Frex]

Hello Tautech,

Maybe it would be a time now to make a  full review of this scope, no ? 
I wait for this, but nothing appear yet, i saw only commercial short movies...
It seems that would interest lot of people here.
(even if, i know, somebodies tell that it's "same" as SDS5000).

Even if I preferred to buy another model, I find this oscilloscope very interesting and I also don't understand why there is no review on this one.
Siglent could sell a lot more if there was a little more advertising on this model.

I don't know the numbers but Rigol must sell tons of MSO5000, and at the same time, apart from this topic, nobody knows how perform the SDS2000X+

Not by me sorry as it might seem biased. 
Plus as yet only some 30 mins have been spent with it and it's still getting to know me.

Most unfortunate was the release timing just before the Chinese Spring festival and then to have a further 2 weeks lockdown due to the virus before more units could be manufactured and shipped to satisfy the apparent demand. Add to this the current shipping delays and it all couldn't have been planned much worse. 

It is an interesting DSO, very like the SDS5000X (yes I have both) with a wealth of capability and in the short time playing with it quite intuitive to use ....but I already have some 5000X experience to call on. 

A local YouTuber will have this one soon to satisfy curiosities.

Some investigations of the inbuilt 50 MHz AWG sine wave at max p-p output and max frequency into 50 ohms.
Peak hold 2Mpts FFT with markers on harmonics.

New arrival but too busy for a bit to even unbox it. 

Have you decontaminated it? ?

Since they run the same software they should look and feel pretty much the same.

I think that is a great bonus for the SDS2k+.

Oh hell and I've been opening Siglent boxes all afternoon !     
Took 3+ weeks to get here so it should be safe however this one is a low SN# and made back in December.

There are a few little things I've spotted are different however as the 5000X apparently will import some of the 2000X Plus FW they are likely to become more alike in some respects. (according to Performa01 early in this thread)
Debug code is the same and USB tricks equivalent too.

Oh, you asked for DHL-Quarantine Shipping ?   


I've never played with this equipment but I like it. I think it covers a sweet spot very hard to beat!

Please go to the top of this post. Performa1 has already shown many beautiful things.

Hello,

I saw Performa1's beautifull screeshots !
But It is also nice to see the instrument in video to have a better understanding of its ergonomics and how it performs against competitor on same signals.
If I had no interest in ergonomics or responsiveness, I would have bought a Picoscope.

I also tried AWG and was surprised that the 10 MHz square wave looked like a sine. Everywhere AWG praise and then this. I am a bit afraid to order AWG a whole new function generator if it would work similarly. Do you have a good experience with a generator or similar that can handle even higher frequencies and is not a wallet killer?

[TK]

Can you please post a picture of the 10MHz square wave?

[Martin72]

I won´t believe it, so I have done it too…

And again: On the usb stick there are six screenshots - But if you put it into the siglent and take a shot, it will always overwrite png1 instead of going ahead with png7, 8, etc...

You don't believe it, but right?

Use a direct BNC connection and switch to 50Ohm.

[Svrbinek]

This is what the 10MHz square wave of the KMoon DY6800 DDS looks like.

BNC direct connection and 50Ohm were used. The AWG was also used BNC (otherwise perhaps not) and 1MOhm but 50Ohm does not paint better.

[TK]

What is the rise time?

[Martin72]

In he first screenshot, you didn´t used the 50Ohm input - I´ve used it, have a look at the pic.

KMoon DY6800 DDS

Well....

[Martin72]

What is the rise time?

Appx 25ns

[Svrbinek]

Yes, in the first frame it was not used on the screen, it was used additionally and the rendering is the same except the amplitude. And that's why I ask. is it supposed to look like that? If so, what does it look like at much higher frequencies?

[Martin72]

is it supposed to look like that?

It´s not the scope´s "fault" if you meant this.
With a leo bodnar 10Mhz pulse you get much "sharper" edges, depending on the bandwith of the used scope.

The datasheet isn't terribly precise about the bandwidth of the AWG, it only says 50MHz max frequency and 125MSa/s. Maybe a 10MHz square wave is already pushing its limits?

Not familiar with the instrument, but it doesn't look like the 20MHz bandwidth limit was engaged?

[TK]

Square wave max frequency is 10MHz... and it says <24ns rise time

As I saw his post, I took my scope and reproduce it, with 50Ohm selected and full bandwith.
The internal awg is simple worse in that case and don´t bother me at all.
We all know there´s no alternative to a stand-alone awg yet.

[maginnovision]

We all know there´s no alternative to a stand-alone awg yet.

Sure, but that's still shockingly poor.

[Martin72]

I simply ignore this function.
Maybe some scopes have a suitable awg in-built, but the fact there was no more than 2.5vpp amplitude output level makes it uninteresting in general.

[TK]

Siglent is charging a significant amount of money for the built-in AWG and they have expertise on standalone waveform generators, why screw it by building a low quality one inside the unit?
