content: It is SDS2000XHD. Hardware 12bit, max 2GSa/s, 200Mpts (≤2ch 2GSa/s 200M // ≥ 3Ch 1GSa/s, 100M )Models (outside of China1): SDS2104X HD, SDS2204X HD and SDS2354X HD.1Model SDS2354X HD Option 500MHz is equivalent to China domestic model SDS2504X HD.It have 2GSa/s 12bit ADC's and freq BW range 100, 200 and 350MHz. (Option: 2ch limited 500MHz1) and 200M memory.Display is 10.1-inch capacitive touch display, resolution 1024*600Of course scope support mouse and keyboard operation which allows smooth and fast use.1500MHz available only when ADC's are in interleaved mode (2GSa/s). When ADC's work in non interleaved mode BW is limited to 350MHzIt follows an already familiar structure. 2 x ADC 2x 200M. Each ADC is divided into two channels.One ADC for channels 1 and 2 and other ADC for channels 3 and 4.This allows two channels to be used simultaneously for both 2GSa / s speeds as well as 200M sample memory.On the other hand, if all channels are in use, then all channels have a sample rate of 1GSa / s and a maximum memory length of 100M.This model does NOT in any way replace the 2000X plus model.The SDS2000X Plus and SDS2000X HD are two completely and totally different devices, each continuing in parallel in its own segment, even they have same frequency band and same sampling speed. So don’t let the number 2000 lead to the idea that this would now be the newer 2000X Plus. It is not now or later. Even the price is at least double,inside China(!), compared to the SDS2104X Plus and 2104X HDThis model have quite low noise front. These aretypicalvalues:2354X HD: 65uVrms @1mV/div 50ohm, ENOB 8.42204X HD: 55uVrms @1mV/div 50ohm, ENOB 8.62104X HD: 50uVrms @1mv/div 50ohm, ENOB 8.7ENOB (typical):@ 99.99 MHz, -0.5 dBFS input, 20 mV/div scale, 50Ω input impedance (100 MHz model input is 49.99 MHz)Math channels 2 (note: Average and ERES are now rt acq modes, they are not channel math.)Naturally cascaded math channels is supported.- FFT max is 2M (221)pts (max 2x FFT 2M simultaneously)3 acquisition modes (as is also least in SDS6000A).- Auto (this is Normal default mode with user definable memory max limit.)In this normal mode, independent of memory depth, whole memory length is visible in display. In this mode also automatic measurements can "see" whole length (with full sample resolution or more resolution due to interpolation between samples with fast timebases)- Fixed user selectable samplerate- Fixed user selectable memory lengthIn this mode, part of memory length can be hidden outside of display horizontal border or borders, depending t/div and memory length and trigger position what user have selected. This "ancient" mode have also been, and still is, in Siglent conventional DSO models (but just forced, not user selectable and adjustable)Restriction. Data for different functions, example automatic measurements, math etc can get only from displayed part of captured whole length (independent of display scale, data is always least full sampled resolution. When stopped, user can select different position and/or different t/div for zoom out or in.Also there can select fast and slow Acq mode as have been in all Siglent SPO (DPO) models.In slow mode, as in all Siglent DPO(SPO), it works like old ancient DSO. Trig,oneacquisition, display....t,a,d...t,a,d....My test setup was very poor... it was not real BW check at all... just fun playing with stepping sweep using old HP "state of art" tens of years old boat anchor (what still havesomeamazing good things).Signal: 0dBm out, stepping sweep. HP N out to SDS BNC, Suhner RG223 1.50m (cable attenuation and mismatch not corrected, 0dBm is in HP out port.

content: I like the frontpanel design of the scope...Although some hard buttons are missed in comparison to the sds2k+, like history or decode...QuoteIt´s time for a "HD" scope from siglenthere...RTB is still the only affordable one with more than 8 bits native resolution.QuoteOK, got it...QuoteBut why are siglent continuing with naming the models so nearby, when they are significant different ?2000X, 2000X+, 2000XHD.....QuoteDouble....Same screen, same Samplerate, same memory, same input (1M/50Ohm, without sensors like the 5k got), same bandwith..There must be more differences than "only" 12 bit ADCs for double the price.Maybe 4 match-channels at last...Nevertheless, an interesting scope.When it´s buyable worldwide.Martin

content: By now it should be clear that pricing in China and EU/rest of the world is quite different. So that is not important. We will see what they will be.Specs?I know many people that had to buy some of the 1 GHz capable devices in a 200Mhz version (so more expensive platform than they actually needed) to gain 12 bit resolution to do power electronics and such.This device will serve that market well..

content: Quote from: tautech on January 11, 2022, 10:53:57 pmMaybe it is because how the market is structured with many layers of traders in between. A long time ago I went shopping for computer parts in Singapore; I went to a shopping center specialising in computer parts but I anything I looked at was like 20% more expensive and they wouldn't negotiate on the price. Lots of surprised faces that I could buy parts so cheap in the NL though.

content: Very interesting, and good to see innovation continues in this field. Also seems to have undergone some design changes on the front panel, making it quite good-looking (even if that is a personal opinion).QuoteWith the resolution of the ADC going up so significantly, I cannot help but wonder whether a higher vertical screen resolution would not have been desirable... Of course, we can zoom in, but still...

content: Quote from: tautech on January 12, 2022, 10:11:23 amSorry I wasn't clear but I meant what are the differences specs wise between these two series. OP's opinion is that these two are totally different instruments for different purposes but other than the bit depth, I don't think there are other differences in the specs(?)

content: Quote from: pope on January 12, 2022, 10:53:14 amObvious things I see after first look at the untranslated datasheet:25 MHz FG vs 50 MHz FG in X PlusAbility to use/control SAG1021I3x USB-A vs 2x for X PlusHigher power usage....the need to feed the 12 bit horsepower.Study of the manual required for deeper understanding of the difference.Like for you this model is totally new for many of us also but rf-loop may have some additional knowledge after his recent extended time in China.

content: Quote from: pope on January 12, 2022, 09:58:58 amThe different (and more compact) physical appearance make it look a bit like the little bother of the SDS6000. It also seems to have new rotary encoders and knobs. Maybe they are all with indents now like in the SDS6000A.Even though 12 bit is the main feature, there are other technical goodies as well, such as:Lower noise floor (e.g. 70 µVrms @ 1 mV/div, 500 MHz bandwidth, 50 ohms)In addition to the math functions, ERES and Average are available as true realtime acquisition modes againWaveform histogramsSome additional triggersDVMSo the feature set is much closer to the SDS5000X now.
