A couple of quick notes on the SDS7102(V) and current software/firmware for it.
For the software, I went to the PC Software tab on the OWON update site (
http://www.owon.com.hk/service_s.asp) and as of this writing it says that 2.0.8.24 is the latest PC software release... but the link to that software is dead! Thinking maybe the uploads were more up-to-date than the text of the page I tried a few other iterations, and found that there *is* a OWON_Oscilloscope_2.0.8.26_Setup.rar there. I downloaded it, ran it through a few AV scanners to be extra cautious, and installed it. It seems to work and the "About" box says it's "Version 2.0.8.26 (build 20141228)". YMMV of course.
For the firmware, I went to the Firmware tab, entered my serial
(be sure to omit the last three digits or you'll be told incorrectly that "The firmware onto your OWON device is in latest version, no need to upgrade, thanks") and downloaded "sds_upgrade_3.2_3.3_3.4.rar". I installed it and now I'm up to version 3.8 on the scope. As usual it started with Chinese menus so I did the "Utility -> H2 -> English" maneuver to change it to English, and that worked fine... until I rebooted the scope and saw that it was right back to Chinese! Tried changing it again, power cycled and back to Chinese! Hmm.
For grins I power cycled, changed the language to English and then
set the clock to something other than the default. *That* apparently helped make the setting stick, and it's been on English ever since.
tl;dr - After updating to this firmware, update the language *and* set the clock... it doesn't seem to stick otherwise.
