SDS2000X-E... Hmm.. I would have expected more sample memory (like in 2000X). VGA output? Museum stuff. (Being the nerd I am, I still have monitors with that, older ones already long-term stored. The least old is also about to be retired, and it only has that VGA input because it was an expensive model with "everything and then some", many cheaper monitors at that time had already dropped VGA input.)
But I guess if the price is right, someone could have use for a "faster sample rate 1000X-E"?
SDS2000X-E have 28M and max samplerate 2Gsa/s. SDS1000X-E have 14M and max samplerate is 1GSa/s. With double samplerate it need double memory whereby the action in time axis corresponds to the same. So, 2000X-E is comparable with 1000X-E. Not at all with SDS2000X what is totally different animal.
2000X-E is 350MHz scope. 1000X-E maximum is 200MHz and with 500MSa/s
(all channels on) it can not be more. Even 200MHz is "borderline" due to fact that it is 0.8*f
Nyquist and it do not have "brick wall" analog BW shape.
With 350MHz 2000X-E is bit better with 1GSa/s
(all channels on) what mean 0.7*f
NyquistIn practice in most cases it is enough if scope can keep full samplerate down to 1ms/div. Both have this.
I think it is quite rare case (not say never) when need more than 14ms
full sample rate when we talk economy class oscilloscope what also use full acquisition memory with full resolution for measurements. Also there is more memory for acquisitions history buffer FIFO. Example in SDS1004X-E more than 100M and two channel 1002X-E over 50M.
But of course also there is one blackbox in human mind... Its name is "nice to have if perhaps some day need"
But then this VGA. What VGA? There is not any VGA output at all. Except indirect what Tau previously explained.
But, I know, there is still lot of places in world who still use VGA and want VGA (but on the ebb). Still some manufacturers (not Siglent) offer in new scopes direct VGA output as standard feature or optional and just because some customers still want/need. They just do not overlook these customers and money is in customers pocket. I really do not believe any second they do it if no one want or need. Manufacturers need look whole marketing area, global world, and not only some western previously developed countries what are now at the top but potentially at the edge of the cliff.
