In China, Siglent have published new 500MHz - 2GHz oscilloscope serie for domestic markets inside China.
Since then, on 12.01.2023, Siglent has released this model series, SDS6000L, to the global market.
(https://www.siglenteu.com/wp-content/uploads/2022/11/675X450.png)
Models are:
SDS6208L 2 GHz
SDS6204L 2 GHz
SDS6108L 1 GHz
SDS6104L 1 GHz
SDS6058L 500 MHz
SDS6054L 500 MHz
I will later update this message more
One unit can have 4 or 8 analog channels and 16Ch digital channel.
Oscilloscope "box" do not have integrated display at all. Just rack or tabletop box
5GSa/s (10GSa/s ESR) and max 500M memory.
Up to 170kwfm / 750kwfm/s sequence mode.
HDMI or gigabit LAN for connect Display and/or computer
(https://www.siglenteu.com/wp-content/uploads/2022/11/SDS6000L-1.png)
These rack mountable units can connect to network for up to 512 analog channels total.

reserved for later use

Huh, had to look at the date of this post. Was not April fools? What is the use case for 512 channels on a single oscilloscope?
-
Many channels in a single scope may be needed to follow rare events at different points in the circuit or with extra sensors, like random failured or radiation effects (e.g. muon showers).
The 512 channels is likely a theoretical limit, like what the SW may do, not really practical and especially not at a high speed. There may be additional limitations (e.g. interconnecing cables so shat that it is not actually possible with existing parts).
The more practical case would be some analog channels (maybe 8) and than quite a lot digital channels (e.g. 32) in a mixed analog / digit setup.
Quantum computers / Qbits tend to need a lot of channels for control and supervision. This may actually want 1 - 2 channels per Qbit. So even small experimental unit with 16 Qbits may need quite some channels during testing / adjustment.

Maybe phased array measurements?

No need for exotic reason (not that it cannot be used for something exotic).
Plain vanilla production test is biggest user of these kinds of solutions.
-
On such a rig can I correlate and do math operations with any of those hundreds of channels?

Not in scopes itself as I can see. This is mostly clock/trigger synchronization. You do coherent sampling on many channels and then pull data en masse to a PC where you combine/analyze. That is very common in 2 scenarios: massive data acquisition arrays (from sensors and such) and production testing where you test whole complicated devices in one go, instead sequentially in separate steps.
These new series of Siglent scopes have interesting characteristics for these kinds of scenarios. 12bit ADC, decent DC offset range, good range of input sensitivities and better than average DC accuracies, combined with decent bandwidth... It allows wide range of test scenarios.
-
Then it's like a bunch of USB scopes time-synced and with an adequate PC software... :(

Don't think so. Looking at the architecture they seem so use a single 10MHz clock source with a distribution panel and some connections back & forth. You can't get to the required synchronisation level that way.

Price?

We can offer that in a couple weeks at release for the 6 models that will be available but for now just an English datasheet.

but for now just an English datasheet.
And.....it´s 8bit.

Really and deeply unfortunately, can't live in China all the time.

What I have been wondering for a while now and also with the 6000...
For the 8bit, 10bit and 12bit versions, will siglent really create three different platforms for this or will this only be "decided" via software.
The former would cost quite a lot of money to produce, the latter could give hope to people like me. :-X

This has been on my mind too and I don't believe anyone will ever confirm or deny it.

Yepp, the only way to find it out will be a teardown.
BTW, never seen servicemanuals with such less information like the ones from siglent... ;)
-

Only if heatsinks are not stuck down like they are on lots of high performance gear these days.
Had a client visit week before last and we got chatting about the SDS2104X Plus we supplied him and as he'd never opened his I had an old warranty replaced PCB for him to inspect which had a # of unremovable heatsinks, some even with hold down clips but no, they were stuck fast.
-
I thought the same with the HD, but user TopQuark was able to loosen the heatsinks on his model without damaging anything.
OK, is a matter of luck whether it could be the same with the 6000s.
-
How does the memory depth work on the 8-channel models? This is not clear from the datasheet; all it says is
- 500 Mpts/ch (single-channel)
- 250 Mpts/ch (dual-channel)
- 125 Mpts/ch (3 or 4 channels)
EDIT: Nevermind. It's in note 3 on page 9.
* 3: C1~C4 as a group and C5~C8 as another group. In a group:
Single-channel: Only one channel is enabled in a group
Dual-channel: Two channels are enabled in a group

I've always wanted a 40" display DSO..... ;D

Except without a LAN connection to a PC, other than basic DSO use what you can do with it is somewhat limited.
Once you run it in a browser you open up its real capabilities.....must get one of those TP Link wireless routers to use it anywhere except at the company workstation. :horse:
First impression was that it's really quite weighty and not at all small, 400x400mm but only 42mm thick. :o
Now driving a 24" monitor and LAN connected so to initially get LAN settings correct for remote access.
Of course to operate it's very much like SDS6000A but with some sync features to align multiple units of these.
Investigations are continuing ...... that has revealed some suggestions to send to Siglent.
I'd have really liked the 8ch model but that's a good bit more expensive.
-
As is customary with a new scope it need be introduced to Mr Bodnar....
A shade under 500ps risetime is not too bad for this 500 MHz model.

I was getting ~485ps :-)

Sexy photo shoot for you all...

and some more...

Defpom review and teardown, maybe a world 1st for this model :clap:

LOL, the mini-carpet for the mouse... ;D
And, surprise surprise...A more than one sheet of calibration. :clap:

A beautiful piece of technology, you can't say otherwise.
The scope, that is, not the carpet.
