I found some files relating to the now-discontinued GDS-2062 oscilloscope. For the sake of posterity and anyone else interested in upgrading the firmware on their ‘scope, here they are:
GDS2000_Firmware_upgrade_steps_r3
I found the firmware, manuals and more on the Hungarian ‘PROCONTROL’ website. I can’t vouch for the authenticity or otherwise of the firmware, but it installed a treat on my GDS-2062 and cured a peculiarity with the controls.
Thank you so much for this! Just dusted off my old GDS-2062 with firmware 0.4 or something like that. This upgrade worked like a charm and made the scope a lot better. Thanks again!
