Unknown western release date.
More info to be added as it becomes available.

As an SDG2000X owner, I would be looking forward to an SDG3000X...
And this:

Unknown western release date.

You should mark it in bold so that it doesn't cause irritation again.

As a not-yet owner of an AWG, I'm conflicted between the SDG1000X and the SDG2000X series.

The SDG2000X series is getting a bit long in the tooth, but the 120 MHz reach and the longer memory are of some interest to me.
I was even thinking of PMing tautech to get some advice - hoping in a "just wait a bit" answer.

This new AWG makes me wonder if a refresh might be in the working for the SDG2000X too...I'll give it some months (I have a voucher to redeem at one online shop, but it's going to expire mid next year), then decide.

I have translated the DS with DeepL, @tautech, can I post it here?
(the © notice wouldn't seem to allow it)

[Martin72]

With 16bit, 8Mpts of memory and almost the same sample rate, the plus is almost the same as the 2000X, at least in this area - it will be interesting to see whether there will also be a plus version of it, in order to distance itself sufficiently not only in terms of frequency.
The models seem a little strange.
30Mhz and then a jump to 60Mhz, that's clear.
But 25Mhz....

[Aldo22]

According to the data sheet, the square wave rise/fall time is 11ns. In the version without “Plus” it was around 4.2ns.
Is that the “price” for 16bit?

Sorry for a noob question.

No.

SDG2000X is also 16bit with comparable rise/fall times.

[gf]

According to the data sheet, the square wave rise/fall time is 11ns. In the version without “Plus” it was around 4.2ns.

Does it also have the "Special circuit for Square wave function, can generate Square waves up to 60 MHz with jitter less than 300 ps+0.05 ppm of period"?

[ Without special circuitry, using only DDS or EasyPulse, a jitter-free, low-overshoot, arbitrary frequency square wave with a rise time of 4.2 ns is IMO not feasible at a sample rate of only 150 MSa/s. ]

I guess Siglent moves from the old Blackfin-based architecture to more modern silicon. It's very well possible that they use the same ZYNQ-based "compute module" that they installed in the SDG6000X (and some other of their gear) -- at least, they already ported all the AWG firmware to that platform and could re-use it in their re-vamped entry level AWG(s). Which absolutely makes sense from a business point of view. Very likely they will also release an SDG2000X Plus some time soon.

I hope upon this supposed "unification" of their "small" AWGs, they will have another look at the firmware and take care of several user complaints and suggestions for improvement...

Sharp observations Tom. 

Certainly that exact module is used in other devices and one I have here is from SSA+/SVA analyzers.

The webserver is an interesting addition for SDG1000X+ and looking at this SVA PCB it would seem support is totally from these processor modules which makes me wonder why it hasn't already been implemented in SDG6000X as they would only require mouse support as they are already a touch display device.

Does the encoder at least work, or do I need to treat it like a princess?   Work meaning it always increments when turning one direction and decrements for the opposite direction.  It updates without missing or stalling.  I would actually want to be able to use it like the encoders on every other bit of equipment I have.

Really, this old hardy annual from you Joe ?
How could we even know as no one in the west has even seen it or has any knowledge of its design other than what we have recently found online.

And I don't even have a crystal ball, do you ?

Although I might get a chance to use one in August when I visit HQ, do you need me to abuse the encoder and report back ?

Yes to get the most out of Siglent DSO's Bode Plot feature the 120 MHz capable model is the one to go for.

SDG1000X+ should be out by then although I have no inside info ..... as yet.
HQ are on Dragon boat festival holidays until tomorrow.

Go for it !
What © notice ? 

[newbrain]

Thanks for your answers, tautech!

Go for it !
What © notice ? 

Attached to this post. Being automatically translated, it contains some peculiar language (judder for jitter etc...) and some blank pages.
I did not cleain it up in any way.

The notice at the end of the document states:

No part of this manual may be reproduced in any form or by any means without prior permission

Oh well, I'll throw you under the bus if Siglent complains 

[mawyatt]

Yes to get the most out of Siglent DSO's Bode Plot feature the 120 MHz capable model is the one to go for.

Can confirm this, works seamlessly with LAN connection. Now maybe Siglent will allow the Bode Plot to 200~500MHz with capable DSO and AWG

Best,

I was hoping the person marketing their equipment would know something basic like this.  If not, would know who to ask.     

There is no need to abuse it at all.  I just want to know if it works with normal use.   

[KungFuJosh]

I think Rob should abuse it and see how well it works. Why not?

[Hexley]

The SDG1000X Plus datasheet shows maximum frequency of the square wave as 20 MHz. Seems to apply to all models. I guess this follows in the footsteps of the SDG2000X, which also has a fixed maximum frequency for the square wave across all models (25 MHz), per its data sheet.

This is a downgrade in performance from the original SDG1000X, which had maximum square wave frequencies of 30 MHz or 60 MHz, for the SDG1032X and SDG1062X, respectively.

That square wave bandwidth on the original SDG1000X always seemed like a unique selling point to me.

With 11ns rise/fall time probably not even the 20MHz look good.
I don't quite understand that. My cheap scope has an AWG with < 5ns rt.
Why is that worse than the SDG1000X?

I once thought that we had already discussed the topic of “more” with the conclusion that 120Mhz is already ambitious.
And that it could become disruptive/lossy above that.
But of course, I would also like 500Mhz.
I also found the specs description of the Lecroy-branded SDS2000XPlus quite exciting:

Bode plot as standard from 10 Hz to 50 MHz available using the 50 MHz function/arbitrary waveform generator, or 10 Hz to 500 MHz using the optional T3AFG500 arbitrary function generator.

[KungFuJosh]

I wonder if their contract with LeCroy has anything do with the limitation.

Well high high would you wanna go ?

SDG6000X models certainly plug and play with Siglent Bode plot DSO's but even the 200 MHz model is ~$1500.

At that level of investment to provide FRA and Phase measurements the ~$1600 SVA1015X comes into play and pushes capability to 1.5 GHz ......in a single instrument !

And with analyzer capability too !

[tautech]

Little more advanced in usage methodology than seeing how fast I can spin an encoder.

Yes please. It's really annoying the way it behaves in the SDG1000X.
