Siglent SDS2000X Plus

[2N3055]

RTB2000, which has only 64 gradations, does not have such "steps". And it has significantly less noise due to the 10bit ADC.

SDS2000X+ is a very good scope for the money. But the intensity grade are not implemented well enough. Why claim otherwise? Let the manufacturer fix it, because this  is only software problem.

Yes and no...

I was talking about front end (analog amplifiers before A/D converters) noise.
Despite 10 bit converter RTB2000 doesn't have less noise, but it has more resolution.

SDS2000X+ has low noise, combined with 8 bit resolution. Front end is quiet enough that you can see quantization steps on A/D converter.
RTB2000 has 4x more vertical points, and you cannot see quantization effects, because front end is noisier than A/D..

I'm not saying this is for sure a reason for this kind of rendering. But sure it can be. I don't have inside information and didn't design those scopes.
And not defending anybody, simply stating facts that it might not be that simple as it looks at first sight.

R&S is rendering to screen using some kind of pixel antialiasing algorithm. That is why waveforms look so smooth. Siglent doesn't do that. They scale and plot actual data points.

What is better? In the end it is philosophical (and aesthetical) question. One is "prettier" and looks "analog  like". Other way might be considered true, and mathematically correct.
If you pull data from buffer, they will both give you clean data without any tampering.

I don't mind Siglents plotting. I know sampling can create artefacts (like moiré effect here) and don't care.  I pretty much expect it..
If Siglent wants to spend development time on more eye pleasing CRT emulation, it is their choice.

I personally thing they should invest all the time they have enhancing and adding to analytic capabilities, which is where this scope shines in its price range.

Aren't the posted examples quite revealing?

In Martin's post, both Rigol and Siglent intesity grading give the expected result, yet there are differences. Rigol rendering looks blotchy, almost as if intensity grading was accomplished by dithering instead of true pixel brightness variation.

By contrast, RTB2000 result appears rather poor. I cannot even see an increased intensity at the edges, like the signal had been a triangle instead of a sine. At a first glance, I cannot see much more than just two intensities in this screenshot.

screenshoots dont reveal the whole truth
you need to see this live, it is like you take a screenshoot of a video, and the picture looks blured or wierd,
but in the video it looks nice and fine

What probes are included from the factory with this machine?

• SDS2104X+: 4x PP215 - Correct?
• SDS2204X+: 4x PP430 ?
• SDS2354X+: 4x PP430 ?

My SDS2104X+ came with PP510, the 100MHz Siglent probes.

[Michael YYZ]

Oh, really?! I thought I've read somewhere that the SDS2104X Plus comes with the PP215 200 MHz probes. Not that good if it comes with the PP510 100 MHz probes, since the scope has an ~180 MHz bandwidth, in reality.

Hopefully, someone here could confirm the status for the SDS2204X+ and SDS2354X+ machines... perhaps tautech?...

[profanum429]

Yea, I ended up purchasing a set of Picoscope TA150 probes that are some 2.5mm 350MHz probes; it was a good deal and figured 350MHz is way more than enough for me.

From the datasheet P3:
Probe (standard)
SDS2354X Plus
SP2035A, 350 MHz, 1 probe supplied for each channel

SDS2204X Plus, SDS2104X Plus
PP215, 200 MHz, 1 probe supplied for each channel

My SDS2104X+ came with PP510, the 100MHz Siglent probes.

Claim the correct probes from your supplier.....PP215 are what you paid for !

SDS2104X Plus has a proven BW of ~185 MHz and therefore is shipped with 200 MHz probes.

What kind of seller have done this.
Btw, how "old stock" your purchased SDS2kXplus is.

Never has my new stock of SDS2104X Plus arrived with PP510 probes....never !
Always PP215 from early 2020 when they were released.

[Elasia]

PP215 200s here from near release and also just got another one like a week ago and another set of PP215 200s

[Michael YYZ]

Thank you so much! This document is exactly what I was looking for.

Checked bit more.

In China domestic markets SDS2000X/Plus have also 70MHz 2 and 4 channels models.
Also here all 2ch and 4 channel 70/100/200MHz models come with 2x or 4x set of PP215.

[profanum429]

Odd, I'll follow back up with the distributor I got it from and see what comes of it, thanks guys! It's a fairly new unit, the cal paperwork is dated from Feb 5th 2021, so I'm assuming it's pretty new.

[Jeff C]

I also received the PP510 probes with the SDS2104x+, but I Called my distributor and they are sending me the correct probes. Like Tautech said, we paid for the better probes, don't let it slide.

On another note, I was playing around with my new scope last night probing random UART data. I was trying to get the packet across the full screen, but for the life of me I could not find any way to do a Vernier change on the horizontal time base. I looked through the manual and didn't see anything either. Is there a way to make vernier adjustments on the time base? or can you only go in the 1, 2, 5 sequence?

This is now quite weird thing.

THis can not accidentally happen by seller so that he accidentally send with wrong probes. If seller tell this ... who believe. If Siglent insert PP215 to every carton and close carton.


But then, very different case it is if this have accidentally happen in factory so that someone have accidentally insert wrong probes in carton. Always can happen mistakes if do something. But if seller tell he have accidentally sent with wrong probes, he lie. Least with my logic and knowledge..

Now there are 2 reports of PP510 probes supplied I too wonder if rf-loop is correct and the the wrong probes have been added to the box at the factory.

There is no vernier and we tackle this other ways.

Move the horizontal trigger position to the left to keep the complete packet on the display.
If you change the timebase the trigger position will off the display or closer to the 0s position but this can be addressed by using a fixed position setting where you can place it anywhere and it will remain there at any timebase setting. Utility>Reference Pos

Otherwise you can use a Zoom window and the H-Pos control where with a touch or mouse click change in which window the timebase and H-Pos controls are active and migrate around the data stream that way.

I am in the same boat. New SDS2104x Plus with four PP510 probes.
Try to call italian distributor...

What´s going on....

What´s going on....

A lot of fuss about $5 probes. Many people probably toss the probes in the bin and buy (or already have) proper ones anyway. Probes that come with scopes are a courtesy item -nothing more nothing less-.

[Jeff C]

I don't think its a lot of fuss when you spend $1400 dollars on a scope and get probes with half the bandwidth than you were supposed to get. I've been saving up for the majority of my internship to try and build a decent lab. Although I do plan on buying other probes at some point, I would like to receive everything I have been quoted

That is not a normal comment from you. They paid it, they are entitled to it even if costed $0.01.

In no place in the invoice it is said that it's a "GIFT"!

[oz2cpu]

here SDS2204X with probes SP2035 with all loose handles so the 10/1 button is impossible to opperate,
then I constantly need to pull the handle back, same problem for this type ?
where do you add the glue to fix this ?
the first thing that struck my mind when i unpacked it all :
"oh no what cheap shitty probes are they"
well well, time to order some propper stuff,
any recommendations ??
links ?
