Reverse engineering FNIRSI-5012H

I really don't have time and interest to mess with this. Especially adding measurements, which are always annoying on the button-based interface.

But also, do you really need scope and a full ADC for TDR? Is not it something that can be done with a couple comparators and a reasonably fast MCU? If this is something you need to do over and over, having a dedicated tool seems like a better option.

And I'm sure tools like this exist already anyway. I had an Ethernet cable break detection feature in a BIOS 15 years ago. There have to be dedicated tools for this.
