Appx 1200€ for the non scannercard version, will make appx 1400 "here".
Interesting..
If I'm not mistaken, the SDM3065X is cheaper in Europe than in China. ¿Something to do with the price of american TE in China?
It's just a guess, but maybe the 346xA series from Keysight and the 6500 from Keithley are much more expensive/not sold in China, and as such Siglent has not strong competition.
I'd be surprised if someone is willing to buy the Siglent for €100 less than the DMM6500 TBH, which costs €1300-1500.
EDIT: Maybe for audio? It could work as a really high resolution scope up to (maybe) 25KHz. It has higher sampling rate than most audio interfaces.
yep seems a Keithley DMM6500 clone at cheaper pricing .... scan card pricing is it the same card as the other siglent who have scan card options ?
we need a teardown, i want to know witch reference they use
but i hate the black trend ...
The DMM6500 is currently sold for around €1450, the Siglent SDM4000 must be significantly lower. Especially since the long-term stability seems to be a little worse.

It's not really at the level of the DMM6500, 50 KS/s is the sampling rate of the KS 34465a in digitizing mode. The DMM6500 has 1MS/s, 20 times higher.
The price is quite a bit lower than the KS, though. It would be interesting to see whether it is as programmable as the DMM6500. I guess they are trying to enter A brand pricing and margins territory. Too expensive even for "A-" tier IMO.
If this new Siglent SDM4000A DMM is even close to the price of the DMM6500, why would anyone consider it over the Keithley?
The DMMs at this level are intended for accurate, repeatable, precise measurements and the Keithley DMM6500 and Keysight 34461-5A have demonstrated such over many years/decades of doing exactly this, these are the "Benchmark" DMMs in this territory, and relatively new unknown for Siglent.
Unless the SDM4000A becomes available at significantly lower cost, can't see knowledgable folks selecting it over the DMM6500.
Don't misunderstand, we aren't a Siglent basher, nor fanboy either, and have a significant repertoire of Siglent gear, including the SDM3065X which is a nice DMM, but doesn't compare with the DMM6500 nor KSs either, however is lower cost!!
Best,

Siglent pricing is a strange thing, taken at first glance. The SDM is quite a bit cheaper in the western markets than in China. The SDS2000X-Plus is also a bit cheaper.
The 2000X-HD is much more expensive though. There, in China, the plus and the HD are quite close in terms of price.
I don't think it will cost as much here. Around 1.000 plus VAT is my guess, if it does come to US and EU. More than that will not sell much, if at all.
For hobbyists the DMM6500 has the old Keythley scanner cards going around for not too much money. We'll see.
The Sigilent meters seems to have a 20 V high impedance range, which can make a difference for a few users.
It is also a bit unclear how good the meters is at higher sampling rates - the Keithley6500 is fast with the separate fast ADC, but AFAIK the front end is limited in the bandwidth, especially in some ranges.
50 kSPS only make really sense if the front end is also fast enough.
For the scanner part it would really be good if this would be a user option, but I am afraid there is the problem that already the connector for the scanner card would limit the maximum voltage.
The picture of the scan card on the web page still looks like the old one.
It is a bit early to say how much different the meter actually is from the old SDM3000 series. It could be as little as a new digital/display part and still the old analog side.
Exactly.
It might be closer to the SDM3065X or closer to the vaunted keithley/keysight models.
We'll have to wait for a review...
yeah could be some rev 2 of the actual model with cosmetic changes, UI changes ?
until we get internal views, we speculate ...
From the datasheet, it's looks identical except for a few key upgrades and a touchscreen.
Just found out about that meter. So they went from copying the keysight UI to copying the keithley UI. Let's just hope it is more intuitive than the DMM6500. I like that meter for the better digitising and graphing possibilities (compared to the KS34465A), but boy do I waste time in configuring it.

A benchtop DMM need anyway some time to reach thermal stability. In the meantime you have plenity to configure.
If you are refering to triggers, scanner, or other extended functions yes you need more time but this is a lab grade instrument not a pocket multimeter that you use to measure something faster.
Also this advanced functions can be scripted as application that can be stored on the scope an start when need them.
Keithley does not offer free software application as Siglent do (and Keysight with some limits). I found Siglent Easy DMM quite nice and useful.
