Tektronix TDS1000B and TDS2000B series hacks
KK:
At this point I have documented much of the boot process, and can probably just patch the firmware where it gets the model id, and force a bandwidth upgrade.
I will use that option last and would still like to figure out how to enter engineering mode.
Making a custom firmware isn't such a bad option though since it would only patch a couple of bytes and these models are long in the tooth now and Tek isn't likely to issue any future firmware updates.
nctnico:
If you can force a bandwidth upgrade it would be nice to see if it has any effect. Maybe the board needs some component changes as well.

It looks like the boards are identical for bandwidth options and even the 1000B and 2000B series boards appear identical.
The display module is color on the 2000B series but the Firmware is identical.

I wonder if any ex-Tek members could contribute by way of PM?

Thanks for that! It helped me fill in some unknown key codes. Notice the Ref/menu button is silkscreened as Power App. On the TPS series scopes that button is labeled Application.
We should be able to activate the power application in these scopes as the code is all there. Of course, the TPS has battery operation so doing some of the measurements would require an isolation transformer on the TDS non-battery operated models.
