Tek TDS340A firmware update
« on: Yesterday at 09:39:50 am »
I have my trusty Tek TDS340A that I use for the occasional project. Pulled it out tonight and realized it's on version FV:v1.09 dated Nov. 19 1996... yeah, almost 24 years old.

I understand they went up to v2.x. Is there any way to do a firmware upgrade? Is it even worth it? Or am I just stuck living in the 90s?

I might just sell the thing and get something more modern but for now it's what I got.

Let me know, and thanks.

a small pictures wiki

But  if it's aint broke, dont do anything.   the newest FW could be for other pcb revisions, if there is ?   Maybe there is a FW log at TEK ?

EDIT: saw this

Service manual  infos  etc ...  maybe youll need to find  the card options

I agree that if it is not broken, don't try to mod it..
Also, think twice before spending your hard earned money for a "fancier" scope, especially for occasional use...

The firmware on these units is stored in ROM, so you can't update it easily.
If you dump the ROM you can make someone happy :
If you find someone with a more recent version you could try to flash it into a blank ROM and see if it works
