BTW: it's a bit weak that you can't save both channels at the same time. Also the "copy" button always saves the waveform, even if you defined saving to bitmap in the "save" menu.
Both channels at same time. This is nice if have but it is also littlebit difficult. (not exactly difficult but they need store separatelly. One after one to the USB memory. They can not merge if do not change "everything".
File structure is 69 bytes header what include all information about scope and settings, after then come data what include only ADC 8 bit signed integers. If do both channels store it need (with this datastructure) only store one whole channel file after one. This can of course do automatic if add this feature to FW. It last twice time and scope need keep frozen whole this time. This feature, store both, have not implemented and user need himself first store other and then store other. If want do one file, well all need do new. Both channels may have different settings, voltage and shift.
I hope they change "copy" button function. It need follow what user have selected in "save" menu. If I have selected "picture" then it save picture. If I have selected wave it then save this captured ADC data. This make scope more fast to use becouse need only push one button for save wave or picture as user have preselected in save menu.
Some this kind of development (many small things) is nice if they can do for FW after collected some good amount of users opinions.
I'm very happy if some manufacturer do so that just before some new model is ready to markets they collect some independent professionals for make useabilitys tests, then collect opinions and make final version.
Also some info on the screen need name different.
Where from come example M: what it means... yes after 5 minutes you learn and remember it is time/div. In some cases chinese language is more nice, it is more powerful if look how much information short phrase can contain. Information density is (mostly) much higher than western alphabetical languages where all info is in serial gueye. And voltage is V, mV, not v, mv.
But it is nice that they can write western alphabeticals.
Try turn you scope menu language to chinese.

maybe it is more nice.
