New toy!!
I think this adds some weight to the value of Siglent's SDS1202X-E... Rigol finally responded.
Love the new designation: DS1054Z + SDS1202X-E = DS1202Z-E
It depends a lot on how outside China price is after goverment subvention to Rigol for export.
It must be LOT of more cheap than Siglent SDS1202X-E. Because its performance is (or looks like now due to lack of more deep info) lot of below it. Yes, Riglol have 24M max acquisition lenght when Siglents max is 14M (and this is just only one thing, some times important but...). Siglent have in waveform buffer up to over 54M but it is then other thing.
No any sign if they finally have gone out from very limiting measurements intermediate buffer length.
Also perhaps still total lack of fast segmented acquisition or more long FFT. No any sign if front end is less noisy than 4 channel models or if it can decode full memory length including also captures in memory (in this some kind of "frame recorder" what it have)
Siglent have always seamless working backround working waveform buffer and a<ll these wafms can full meas, math, decode etc) And same things can do for fast sequence (max over 400kwfm/s) mode captured waveforms.
All measurements can use full memory length so full current samplerate time time resolution even with low time bases.
And Siglent 2 channel model have separate vertical adjustments.
But it all is: what is Rigol price. If it is 200 or 300 and Siglent is 400 then user need think if Siglent some special functions/features and performance is worth for extra money. If they are nearly same, then 99% Siglent walk over it easy. Except if one need Rigol nameplate and it is morfe important than other things. It is fully: what things user need.
If prices are ok and match with features and performance then both are good one for other and one for some other, depending user needs and I like red vs I like blue things.
But if think example very old Rigol DS1052E, this is totally BIG step over it.
