When will Dave get his hands on one of these babies and do a review ?
Yes, if he is serious to test using a Bodnar fast rising pulse generator (30..40ps rise/fall time) so we will see the beef.
However a teardown would be interesting between a 8bit SDS6000A VS a 12bit SDS6000 pro.It's simply different board.. Not much to compare.... or also not. We cannot know until someone had a look under the hood of both instruments. It might well be that there is no hardware difference at all...
It's simply different board.. Not much to compare.
It would be really surprising if the 8 bit version was supplied with 4 x adc 12 bit 5GSa/s.
The price difference must be huge between 8 and 12 bit 5GSa/s ADC....but they have some headroom given the low-end price.
If it is the same architecture, I will think a lot less to buy it and I think someone will be very interested in hacking it if it's not already done

Do you know that for a fact, or are you just trolling ?!

Agree! A 12bit 5GSPS ADC is very difficult to develop and thus I'd expect quite expensive, and with 4X even more expensive. This is not the same as using a TI VGA chip in the front end that can be "programmed" for added bandwidth and followed by a high speed fixed 8 bit ADC like in the SDS2000X+ series. The 8 bit ADC Siglent is using in the SDS2000X+ is quite good tho for an 8 bitter, but likely not expensive.
Very disappointed that the 6000 will not be available in NA with 12 bit ADCs, and not sure how good the ERES will behave regarding ENOB. The SDS2000X+ is pretty good tho, so hopefully Siglent will be able to squeeze out a few extra reliable bits like the 2000.
Soon I guess we'll know when a few quality reviews are posted.
Best,
as always, faster the ADC is, you can interpolate a bit more... So 5GS/s will be able to get a bit better results than 2GS/s for low frequencies.. more samples for averaging is available.

Why would I be trolling ?? What kind of a question is that?
Which part of 4 x 8bit ADC versus 2x12bBit ADC didn't you understand. Which part that it has different memory sizes and general specification didn't you get?
12Bit version has VGA output. 8 bit one has HDMI... etc etc..
Are you one of those people that live in fantasy world that think that PCB layout can be fixed by a software patch? That you can install large BGA ADC converters by software unlock?
Yes, I know it for the fact.. It is different hardware. Only thing they share is case.

Hello Sinisa,
Where did you see that the 12 bit version didn't have the same memory amount and had a VGA output ?
On this specsheet, we can see HDMI and 500Mpts memory. Maybe an out dated specsheet ?

https://www.siglent.com/upload_file/document/SDS6000_Pro_Datasheet_DS0106P_C02A.pdfIndeed. If you put this spec sheet next to the one from the SDS6000A then you'll see there are a lot of similaties AND a major difference. The SDS6000A (8 bit) supports 5Gs/s on all channels where the SDS6000 Pro supports 'only' 2.5Gs/s on all channels. Maybe there is some interleaving going on to get more bits. IMHO it is impossible to say whether these oscilloscopes have the same hardware under the hood or not without doing a teardown of both. Since a DSO is a relatively low volume product the NRE costs for 2 ADCs might be higher compared to developing 1 higher spec ADC and use it in an 8bit mode on lower spec models.
For example: Keysight has done something similar on some of their higher end models where they limit the DSO to use half the samplerate the ADC is capable of.
That is interesting, I was looking at older datasheet, and was apparently comparing to 1GHz Chinese version from that datasheet.
But it still stays the same. 12 Bit converters are much more expensive and also not easy to get.

SDS6000 Pro H12 and H10 2GHz models have 5GSa/s for all channels simultaneously and then one 500M memory shared for all analog channels and as can see looks like same with all 8bit SDS6000A models.

Indeed.
..... this is clearly aimed for the professional market and there is no particularly cheap entry model for all the hackers out there.
We also get a frontend without compromises: full sensitivity at full bandwidth for all models up to 2 GHz.

Difficult to read public data sheets published by manufacturer instead of wild speculations?
You better check your own links: on page 3 and page 12 of the SDS6000 Pro H12 spec sheet it states that it has 2.5 Gs/s per channel with all channels enabled. I don't need to understand Chinese to spot that.

Sometimes some understanding doesn't hurt. These are the specifications in question for the SDS6204 H10/12 Pro, translated from the Datasheet:
Real-time sampling rate: 10 GSa/s (ESR) @ per channel
Memory depth : 500 Mpts/ch(single channel), 250 Mpts/ch (dual channel), 125 Mpts/ch (four-channels)
Some folks here already noticed that the price difference between the various bandwidth models is rather low - so this is a first pointer that
a) the hardware is identical for all models - other than for the SDS5000X
b) this is clearly aimed for the professional market and there is no particularly cheap entry model for all the hackers out there.

Google translate tells me: :ESR: Enhance the sampling rate, obtain better measurement accuracy through 2x interpolation which still doesn't explain what is does exactly.

It looks more like the 2GHz model has different acquisition hardware compared to the 1GHz and lower models.
