Looks nice. Question is price. <$3500 for 500mhz and it's a killer.

Probe detection but not probe supply? Great compromise for the entry class but I guess the SDS2000X will be more a mid-range scope from Siglent's point of view.
Actual 10 bit or interpolation? Probably the latter.
Will it have true pulse width measurement where you can set the mid-measurement references? Now all pulses are read at 50%. Also will the Cursor Control be easier to use the in some of their other scopes? I'm game for buying a new scope at the end of this year (expense it off) for my business, but I have been burned by Siglent last year, so I would need to get my hands on one before I decide to purchase it.
2 GSa/s, BW's 70 to 500 MHz, Storage depth up to 200 Mpts/ch
2 or 4ch models.
8 and 10 bit modes
10" touch display with keyboard and mouse support
16ch MSO option
Standard Decodes: IIC, SPI, UART, CAN, LIN. Optional: CAN FD, FlexRay, IIS, MIL-STD-1553B
2 Mpts FFT.
1M and 50 Ohm inputs.
Inbuilt AWG option
Power Analysis option
I assume 2GSa/s is only true for one channel or two at maximum.
So, what is the sample rate for 4 channels?
Actually, while 2GS/s could be considered enough for 500MHz I guess (even though I'd personally want at least 5GSa/s), 1GS/s or even less per channel would make the higher bandwidth somewhat questionable.
Finally someone made a scope that checked all the boxes of what I am looking for. I really wanted something that one on the bottom rung of a mid-range scope 4 ch 100Mhz, touchscreen, 50 ohm inputs, MSO option, looks nice on the bench, etc!!

@Performa01: Does Siglent have any plans to get rid of the automatic memory depth setting? For me the automatic memory depth adjustment is a total productivity killer. It annoyed the hell out of me during the short time I had the SDS2000.
And how about full memory decoding? It is about time Siglent addresses this too.
@Performa01: Does Siglent have any plans to get rid of the automatic memory depth setting? For me the automatic memory depth adjustment is a total productivity killer. It annoyed the hell out of me during the short time I had the SDS2000.The short answer is no, sorry.
What engineers want to do is capture a record that represents a certain timespan. What is easier and feels more natural:
• Select the main timebase for the required total timespan and then adjust the zoom timebase for closer inspection of details
or
• Calculate the required memory depth from the required timespan and current sample rate, dig into the Acquisition menu to select the appropriate memory depth (provided it could be selected with similar fine granularity as the timebase) and then have to scroll back and forth through the buffer in order to inspect the entire acquisition
?
And how about full memory decoding? It is about time Siglent addresses this too.This is a (mis)leading question. While there are certain (protocol dependent) limits for the total number of table entries (bytes, words, double words, packets) which in turn obviously limits the maximum record length that can be fully decoded (at least if oversampling is low), not many apart from you would consider the following screenshot with a total of 45 decoded I2C messages as not full memory decoding:

You (and Siglent) forgot one very simple use case: trigger on part of a signal and when that looks OK change the timebase to look at the rest of the signal (which was outside the screen during capture). I use this regulary during design verification. And this is much easier to achieve than you think: just set the oscilloscope to the maximum memory depth and leave it at that. I have my oscilloscopes set to the maximum memory depth 99.9% of the time. It is very handy to be able zoom out or pan left/right to examine the signal which was outside the screen. With Siglent's automatic memory depth I'd need to change the time base for each capture twice which is just time consuming and irritating. And why not have the maximum memory depth available? Otherwise the memory just sits there idle anyway.
I also don't see the point of so many DSO variants as Siglent has now.
The 50 Ohm inputs are indeed welcome.
I must still look further for a decent 500MHz DSO...
SDS5054X ?
Can you check total mem depth in History mode when in Decode ?
There's some really good deals on the bit older 8" display SDS2304X, trouble is decode is optional and additional cost.

These have all the above specs you wanted except touch.
SDS5054X ?
It's way out of my price range and anyhow roughly around that money one can buy a used but fully vendor checked Keysight MSOX3104T and while I'm certain that some if its specs are weaker but it's still a 1GHz scope.
I'm not biased by brand or don't necessarily look for a brand new device (provided that it's not ages old) but do you think that it provides the same value?
Can you check total mem depth in History mode when in Decode ?No matter whether it’s decoding or not, history is always close to the total memory size, i.e. 180~200Mpts per channel pair.
