I'm continuously working on this Curve Tracer in my spare time. I designed a Vishay VO14642 photovoltaic SSR into the circuit. It is quite a nice, but pricey device.

I thought why not try to order it from Aliexpress. For control I also ordered a few from Mouser.

Both devices on the same board:

The original on the left

The fake measured

The original measured

This device should have 0,25 Ohm maximum on resistance.
