THS720 firmware upgrade

I'm sure this has been answered, but is there a way to upgrade the firmware on a THS 720? I've just purchased one and it's running 1.03, which I suspect is a little long in the tooth. 

Thanks!

Hi Jerry,

Sadly we no longer provide new firmware for the THS720.

That's a shame. Seems to be a great little 'scope. Thanks for responding!!! 

I posted similar information in another thread for the THS730A, here is the info edited for the THS720:


The firmware update can be done with some delicate (!) soldering skills.

By removing the flash chip U1 from the motherboard (It's on the back so you'll need to completely remove the motherboard from the scope), you can place it in a chip programmer like the xgecu TL866II Plus with a TSOP adapter (and 8-bit carrier board) and flash the new firmware.
However, as this flashes the entire chip, you will then need to recalibrate the instrument, after doing a full factory reset, SPC, etc.

You can find the firmware images here, the latest for the THS710 and THS720 is 1.03 (they both use the same firmware):

So it looks like you have the latest for this scope already anyway, unless someone else finds a later version...

Note, DO NOT mix firmwares between the THS7XXSTD/THS7XX and THS7XXA/THS7XXP models, they are not compatible due to hardware differences!


I'd love to get documentation on the internal connection (or get my hands on an original programmer) to figure out a way to flash the firmware in a more safe and 'official' way, but such is life...

 

Much appreciated, Jared ~  as you note, I think I'm at the latest right now and things are working pretty well, so I'm not going to risk blowing up a perfectly good unit. But that information will be useful to someone who needs to get up to 1.03, so thanks for posting it!
