Osci Video PCB

Based on the XYZ converter by MrSlehofer.

This PCB design is ready to be ordered and assembled from JLCPCB!

Just upload the files in the production_files folder to their webshop. All settings should be fine, just some manual translation of the RCA connectors may be needed in one of the last steps.

Warning: in the board revision V1 the PNP transistors U2 and U3 were placed the wrong way round. This has been fixed.

The V1 revision did not work at all. The R1 resistor had to be reduced to 6k8, the R10 resistor to around 24k, for my test setup to show a proper picture.

Also I’m referencing the Z output to GND, instead of to +12V like in the original PCB design. Otherwise with scopes like mine, where the XY and Z inputs all have common grounds, would cause a short circuit of the power supply. Sadly this inverts the brightness of the video drawn on the scope.
