LeCroy Probus reverse engineering

That's awesome!  Are you willing to share the design?

Yes. I wish it can help.
Tek TCP202 current probe isn't sensitive to the +-15V supply voltage, so I used the +-12V suplly rails on the Probus directily and it works well.

I use the easyEDA to do the design. I found it's a little weird after conversion. So I attached the Gerber files.

Hi, for those interested, I am attaching the results of reverse engineering of HFP2500 probe and the protocol on I2C it is using. The contents of EEPROM is published on this forum somewhere.
One interesting thing - this probe has RGB LED that turns on the color matching that of the trace on the screen. However, I did not reverse engineer how exactly the LEDs are connected. I guess that there is some transcoding in PIC firmware. But if someone can suggest a simpler circuit that converts the bits as they are sent by the scope to 3 LED wires, it will be great. The codes are in attachment...
