Siglent was hanging to death when I was saving waveform data to flash drive (two different). I had to unplug its power cord in order to reset. How can I set wall clock time? All files I created were 50 years old
Tine of clock.
There is not real time clock in any SDS1000X series oscilloscope.
I have tested waveform data saving to USB stick. Used Kingston DTSE9 8Gb. Formatted using windows for FAT32 and of course only one partition.
Image, just need push Print and without any hassle like Owon image in png format is stored. No change in menu display or any other.
With Owon I need use Save menu. So in all image there is Save manu buttons in screen bottom. I can not save image so that there is some oscilloscope settings menu visible like in Siglent. Also I need do many things before it save image. After I press Save, then I need select what I save and I select image. then after I push sub menu save after then come pop up window for naming file what also need push enter or multipurpose button on front panel. After then Owon start storing this 1.4M BMP image, and this process is quite slow. If I need do documentation during my work it is really terrible slow. Who pay my salary when I play like this.
With Siglent, just single button. and immediately it tell image is saved. No any button circus. (and I have touch panel screen what helps bit, but still total mess. Is this made as replacement for game console or is this made as serious tool for work? Perhaps hobby use user can accept this mess but for more serious use. Who will pay my salary if I am playing fun with this. There is good things also in Owon but UI is really mess what makes real useability really to lower class bottom. Small things but important things.
Siglent also, its UI and overall useability is far better but not at all perfect.
Side note:
Every company in China, including Taiwan island, need learn lot of for ergonomy, useability and industrial developer of the product outlook design. They all are terrible or horrible if look critically these designs.
But, also it need kindly understand that Chinese industrial design is very very young in this T&M instruments area. They are like childrends. Some, example Tek or HP, have done these industrial designs tens of years. They have inside house long history for develop good hardware ergonomy and also software made UI ergonomy (exept some times now it looks like they start forget - dementia perhaps due to old age).
In some old HP oscilloscopes UI is really near perfectionism. examples in some ancient 54xxx series (with these limits what this era FW make possible). How these young just more or less short time ago started companies can do this same.
If want know more just read all HP journals from beginning. Design philosophy is there (but not only there, also other sources are availlable). These journals are like free high grade learning books how things in indutry need think.
Who is first Chinese company who adopt this design and innovation and manufacturing culture and start developing towards A or A+ class. In A,erica they have started dementia and many companies actively try forget all good things. Like in Danaher and like in Keyshit.
And this, screen image to USB stick is what I do lot and this need really work fast. With Owon it is not possible to do fast enough.heard from many people that screen dump is most frequently used save function. They have even Print button in front panel but no, this is only for physical printer.
How can they do screen dump like this.
Then waveform data.
With Owon, procedure same as with screen image dump.
There can select wave: BIN, TXT or CSV.
If I select 10M memory, save all and CSV. It is not fast at all. It takes long time (and in this, Siglent is even more slow but also it have no 10M selection, it have 14M or 2x7M)
Also TXT. Same. What ever it is. Also CSV is text. so what is Owon TXT vs CSV. Siglent can also select BIN, CSV but third type is named MatLab.
Owon, screen dump. During save, scope acquisition freezed. It takes roughly without clock, say half minute.
Owon BIN save (10M, All) During save, scope acquisition freezed.
Owon CSV save (10M, All) take coffee break. During save, scope acquisition freezed.
Owon TXT same. Take coffee break, During save, scope acquisition freezed.
Without thinking time or button acrobacy it works - mostly. But example now, after CSV save next I select to save BIN. Now screen small pop up tell that please install fat32 disk and make sure it have 4k cluster size. Just after it save CSV without pproblem. No way, always same. Then I try TXT, again, no problem but as slow as CSV.
Reboot Owon.
During this I also check USB stick. Now windows tell it have problem and need "repair" Ok, done. Perhaps this was problem? (no it was not problem) Try again with Owon. Again, same thing when I try BIN. When try save there pop up small window for give file name. I change this file name. After then it accept save BIN file what takes some seconds. Then after I try save BIN again, same warning FAT32 and 4k cluster. Again. Change filename and it works. Slow. around half minute.
What a mess.
Then with Siglent.
Screen dump. Push Print button in fron panel. Just blink your eyes and its done. PNG is in USB.
(it can do also in Save menu if really want but also there can select image type, BMP, JPG or PNG and if invert or normal black backround image. THis setting here is used for front panel Print button)
PNG saving to USB is really fast and even BMP is faster than in Owon. Who want BMP, for what as long as PNG can use.
Saving waveform data. 2x7M
BIN fast, counting in mind, perhaps 5-6 second.
CSV slow, go to coffee break. More slow than Owon. Scope still do normal acquistion and display waveform but wfm&s speed drops some amount.
During save process settings can not chage but wfm is eunning and can still watch on the screen, unlike Owon what freeze display during save.
MatLab. Same as CSV.
I did these many times and all times it works without crash like you told. So please explain what exatly you did when it crash to state where ypu need unplug power so that it can report to Siglent for fix if there is error in system or if it is user error what can stop changing FW so that some things are locked from user during save process running.
It need note to some random readers that CSV and MatLab or CSV and TXT with Owon and Siglent or what ever brand produce quite big files. Example Owon with 10M memory settings, save all (2 channels on) produce around 330Mb comma separated values text file (filename.csv) Example OPenOffice or LibreOffice can not open these files due to big size.
Here small sample from Siglent .csv
Total length is 7000000 rows data + header some rows including some information about scope and settings, (2 channels, both 7000000 sample.)
