There is very little difference in price, but which one is more worth it? --- End quote --- If you need the BW SDS2202X-E everyday as it is a 350 MHz design. Very similar feature set to SDS1104X-E however the 4ch model offers more total capability if BW is not a concern. --- End quote --- And about what is discussed in this thread, about noise, are the two the same? Are both models hackable? |

At this time I own one Rigol 1074Z (mod to 1104Z) In upper part of image (Rigol) there is also note about data used to measurements, today we know more also about this and it really use very extremely tiny intermediate buffer for measurements when Siglent use full acquisition data. And then bottom part of image Siglent SDS1104X-E. Settings as same as possible what was used with Rigol for fair compare. 1mV/dif used because Rigol did not have 500uV/div. (also 1mV/div in Rigol is not true full resolution, it is some kind of production from 5mV/div) Around 60uV AC RMS (Stdev) is quite good for 100+ MHz bandwidth with 1Mohm inputs. Typically it is much better than service manual "go to repair" limit. This is many years old.. Also I have measured several SDS1104X-E and I really can say that common value at 500uV/div is between 50 - 65uV/div Stdev (AC RMS) --- End quote --- Because the rigol shows the signal much thicker if the two are at 1mV/div? Edit: Sorry..., I thought the same signal was being measured in both |
