Tektronix TDS1000B and TDS2000B series hacks

<< < (29/33) > >>

TheKellerman:
After repairing and upgrading two scopes I want to point out that -SC is not the same as -EDU. The EDU firmware will only boot if the device ID is EDU (0x28 for TDS1001C-EDU or 0x2A for TDS1012C-EDU) or if the ID is a B model (probably same firmware base?). 0x28 and 0x2A are not listed in the firmware that Fieroluke disassembled, so if you update an EDU model with C Model firmware, the scope wont boot. And I assume that the EDU firmware knows only about EDU and B model IDs, not Regular C models.

However, you can put the C firmware in a EDU device, desolder the flash, change the ID to a C model and update the CRC. That way I upgraded a TDS1012C-EDU to TDS2022C.
Another way would be to keep the EDU firmware and only changing the ID to TDS2022B, but it looks like the C firmware has more features.

And to answer my own question from earlier: https://www.eevblog.com/forum/testgear/tektronix-tds1000b-series-hacks/msg4705982/#msg4705982
the EDU FW (like the one found on ko4bb.com) will not work on a B model hardware!

Hi Fieroluke, I have a tds1012c, can I upgrade to 2024c, can you help me? Thank you very much!

Fieroluke:
No, you can‘t change 2 to 4 channels.

Changing from b/w to color is said to be possible, but I have no experience with that.
So, getting a screen and assorted components from a tds2000c series scope may be possible, but probably cheaper to get a working color model for cheap.

And for the monochrome TDS1000 series, your TDS1012C seems as high as it can go.

lern01:
Sorry, Is it possible to upgrade to TDS2022C?

vdetal:
Works with monochrome display too.
Tested on 2 pcs 1001B.
