Siglent SDS2000X HD, 12bit, 2GSa/s high definition oscilloscope serie.

Let's hope Siglent doesn't buy them individually... 

No, of course they won't buy at Mouser & Co. But even so it's not going to be cheap.

One thing I have noticed that's not available on the SDS2000X Plus, is the FFT is intensity graded and can be color graded as well, which is pretty nice.

Or the increased demand could make them cheaper.

I was imagining the opposite consequence due to scarcity.

well, only if you tells us how you did it ! Bravo by the way...

If I remember it right, you still got your SDS2K+ avaible, unlike me...
Would be interesting if you go on both to all menus and list the differences - This is what I wanted to do when I´m back at work and got a look on a SDS2K+ (And take it to home for a weekend)...

[kripton2035]

yes +1 for a side by side comparison of the SDS plus vs the HD
apart from the 12 bits ADC, there is no clear difference for me.

seems a good time to replace my good old PM3394...

It doesn’t make too much sense to compare software features, because unless there is a lack of resources, any feature might just be one new firmware version away.

Below I’ve listed the differences/advantages of the SDS2000X HD that come from different hardware – but some of that might trickle down to the SDS2000X Plus eventually, like the better encoders. It also lists the feature differences in the firmware, that are resource-related and most likely became available because the 10-bit acquisition mode has been dropped for the SDS2000X HD.

• Looks like the little sister of the SDS6000 – compact and even more solid housing
• Better rotary encoders (all with indents)
• Quiet as a whisper because of the big temperature-controlled fan
• High quality passive 500 MHz High-Z probes as standard accessory
• Additional USB host port at the backside
• True 12 bit ADCs
• Twice the sample memory (200 Mpts @ 12 bit)
• Better accuracy (0.5%)
• Average and ERES as realtime acquisition modes
• Qualified Trigger
• Nth Edge Trigger (not strictly required, you can use Holdoff by Event for this)
• Delay Trigger
• DVM
• Waveform Histogram
• Internal AWG limited to 25 MHz sine (SAG1021)

Disclaimer: I cannot guarantee that the above list is complete.

EDIT: better accuracy added.

I did get to have a play with one of these last weekend 

Very cute, neat size great price, hackable to the stars if you are looking for a sub 500Mhz accurate scope for general power electronics work with nice features that won't break the bank or take up much desk space, then look seriously at the new sds2000x. Apprantly the cost was going to be more favourable, although a large consumer of these products made their feelings known and hence why the 2000 is the price it is. That said you obtain  alot of scope for a sensible outlay especially with the very astute folk on here with the superb 'releasing skills' when it comes ot SW options.

Also had a play with the bigger 6000 series, again a nice scope with quality features that you guys have already liberated.

Mildly impressed again, Siglent starting to benefit from Lecroy more, just a shame Lecroy are quoting 18-24 weeks for another Wavepro HD, the joys of the current state of affairs in the world 

At the moment R&S are pumping quite stupid deals on the 2/3 & 4000 series scopes which for some mybe just to good to miss.
However do try the latest Siglents, you will be pleasntly surprised imho

Question in another format: makes more sense to compare the SDS2kHD to the SDS2k+ or the SDS6k?

Compared to the SDS2000X Plus, the SDS2000X HD has a higher end look and feel, yet it is still the 2000 platform in terms of hardware. And this, among other things, means 500 MHz / 2 GSa/s maximum.

The SDS6000, with max. 2 GHz / 5 GSa/s per channel, even though still an embedded platform, has vastly more horsepower (its 8 Mpts FFT updates faster than 2 MPts on an SDS2000X Plus/HD) and the resources to support four math channels (which process serious amounts of data and not just a small secondary buffer) and applications like Eye Diagram and Jitter Analysis. And of course there is the active probe support.

So it is still self-evident to compare the two 2000 instruments, yet the SDS2000X HD gets quite a bit closer to the SDS6000 in terms of features. Other than the obvious goodies of a midrange scope that I've listed above, there is not so much difference to an SDS6000, apart from the number of math channels.

Oh, this reminds me that I forgot to mention the improved accuracy of the 12-bit instrument. Have added it to my list now.

Maybe some clarification on the memory depth, because the table lists both instruments identical as 200 MPts. In fact, the SDS2000X HD requires 16 bit wide memory to store a sample, therefore 200 Mpts mean 400 MB. On the SDS2000X Plus it is just 8 bits per sample and 200 MPts mean exactly 200 MB. Consequently, when the 10 bit mode is activated on the SDS2000X Plus, then the available memory halves to 100 MPts.

You were serious when you said you wanted my filter

And it has arrived today...quiet fast.
Assembling it, test it and post the result of the bode plot with more points as before.

Absolute....

, yet it is still the 2000 platform in terms of hardware. And this, among other things, means 500 MHz / 2 GSa/s maximum.

1000 series = 1GSa/s max, 2000 = 2GSa/s max, 5000 = 5 GSa/s max.... ?

While 6000 is a kind of its own, as you can see it´s missing the "X".

[TopQuark]

Another minor thing I noticed about the HD vs the Plus, is how you can choose to see the time domain waveform when doing bode plots.

This is great as you can see if the signal source is driving the DUT into a non linear mode, useful for stuff like measuring SMPS frequency response etc.

I hope they can have a third mode where they can overlap the time domain and frequency domain graphs together, like how the Keysight scopes do it.

Would also be nice if the time domain display shows a slightly more zoomed in waveform on the X axis.

I'm sure they can add this feature to the Plus if they wanted, but we'll see.

any hint on how you did this ? thanks...

Until the process gets improved in the future, you need to take apart the scope to access some pins, have some Linux knowledge, and a lot of help from the man himself to do the magic, you up for the task? 

Anyways, knowing that the process is indeed possible is not enough of a lure to just go for it? 

[kripton2035]

no problem for opening and accessing pins, no problem for linux.
but if the process involves scanning with xrays the scope to detect some hidden combinaisons inside some chip I'll pass !

[TopQuark]

One thing I noticed when using the SDS2000X Plus is the waveform update slows down when you activate measurements, and I didn't perceive such slow downs when using the SDS2000X HD.

So I put the Plus and the HD side by side for a waveform update rate test. Channel one of both scopes is hooked up to the trig out of the other scope, while channel 4 is hooked up to a same 1MHz square wave from a function gen.

First 4 screen shots is the DUT triggering on the 1MHz square wave, with or without measuring the square wave. Sample rate, time scale and memory depth of the DUT are set to be the same.

Second 4 screen shot is the other scope triggering on the DUT trig out signal, with DUT measurement on or off.

IMO, two conclusion can be drawn from my test,
1. The waveform update rate of the Plus is faster than the HD with my particular DUT setting.
2. Yet, the waveform update rate of the HD is less impacted when measurements are turned on.

[kripton2035]

seems normal to me as the plus is given for 120000 wfm/s and the HD is given for 100000 on their datasheet.

[Performa01]

seems normal to me as the plus is given for 120000 wfm/s and the HD is given for 100000 on their datasheet.

... and the HD always has to move twice as many data. There is only one or two bytes, 8 or 16 bits, so the 12 bit instrument has to use the 16 bit data path up to the final screen representation all the time. A fair comparison would be to the plus in 10-bit mode...

[Martin72]

@TopQuark,

Here a document from siglent how to test max. updaterate on 2000Xplus (and HD, why not).
As I remember it right, rf-loop didn´t like this for several reasons I´ve forgotten.
