Hello, Im running HW 0x555583e8 SW 120224.0 and have been using my scope a lot recently, being no master I found an annoying bug,
When having just captured a single seq and pressed any menu button, the graph gets compressed in order to get space for the menu bar, this seems Ok, but if you want to measure time with the cursor, you end up measing an horizontally (time) compressed graph, aka, you measure more time than the actual real time.

shit, i have to answer your PM ...
There is newer firmware since day or two available on Hantek website, it does not change that much (if any)
but it is GPL compliant^^
Regards the measurments, sure click Meas button, chose with blue cursor keys the item you wish to change, click F5
to modify and select with F1 the source of measurments.
There are 4 measruments visible in same time, however you can scroll with these blue cursor keys between 4 pages - so you can setup on page 1 and two channel1 and pages 3 and 4 channel 2 - then in principle just scrol up and down between
pages.
tthere is major bug inside this firmware, or actually last (already 3) firmwares. The reason is that Hantek/Tekway
is working on the timebase procedure - the whole part has been re-written and does have bugs.
They has been notified about and actually they knew it. The good news it - they working on several bugs now,
so soon new firmware with fiex timebase will be available (and probably already the version 1:2:5 instead of 2:4:8 timebase ratio)

The problem is, I have done what you said, but it does not change to ch2 when I press F1 (yes, ch2 is on).
Even when channel 1 is off and channel 2 is th eonly one displayed, it won't display amy ch2 measurements or allow ch2 to be selected by pressing F1.
I will upgrade the firmware and see if this is fixed.
(PS, I didn't send you a PM, so it must have been someone else).
Thanks again,
@Mark
My DSO5102 desktop scope behaves the same. I think this is a long standing bug, I posted about it here :-
https://www.eevblog.com/forum/general-chat/hantek-tekway-dso-hack-get-200mhz-bw-for-free/msg94907/#msg94907
But I think you described it better than I did.

Installed 120423.0 and it has fixed the above issue, thanks. I now have measurements on channel 2.
Quote from: MarkInstalled 120423.0 and it has fixed the above issue, thanks. I now have measurements on channel 2.The DSO1202B crashed at the weekend while I was playing around with it, and when it rebooted I had lost measurements on channel 2 again! Firmware still showed the upgraded number.
Flashed firmware again and it's showing channel 2 measurements again. Maybe there is a way of resetting the scope which will fix this if it happens again instead of reflash.

Sorry can you rephrase that? Im not sure what you mean.

Ok I think I got you. Thanks
I was just curious about the possibility. However isn't it possible with the current kernel to create a mounting point in the filesystem that points to the SD card as an extension of the root filesystem? Because if it is, than we could use that to record waveforms on the scope I believe. But maybe it is just wishful thinking on my part.
Use the attached usb tool (special version of www.dreisiebner.at/dso-usb-tool ), to delete delete the file /param/sav/run* (which is the setting profile)
In principle even the "default" button (save button and then F4 or F5?) should do the same,
if not try to delete the file above. You can also delete the sys.inf and then reboot:
rm /param/sav/r*
rm /sys.inf
EDIT: The attached usb tool is actually special version for handhelds, not
everything works but shell/settings/screenshot are already ok.
You will need to remove the "zip" in file names and use winrar to unpack it.
Hi guys.
This month my Hantek DSO5102B decided enough is enough, and froze up (knobs not working) so i had to open it up, hack it with my Seeeduino via UART, but when I did I found something unexpected. On the right side (top view) of the scope main PCB I saw a MicroSD card slot facing the buzzer. This got me curious whether it is something usable or not because i saw the pads on other images but in my case it was populated. Should I desolder the buzzer and try it out?
I am teetering between the Hantek and the Owon. I like the Hantek because of it's features and because it runs Linux. The Owon doesn't have the split zoom and update speed but it offers battery operation which would be handy for some things that I do. Kinda like a cordless drill.
How about a snapshot of the current situation?
if you plan on hacking around with your Hantek on regular bases, you might want to look at the procedure a number of people have used to add an easy to access uart connection to their das_oszi:

Nice!
Considering the amount of time all this has taken - is there Tinhead Beer Fund somewhere to receive small tokens of appreciations ?
