This thread has been quiet for some time so allow me to add some info.
First of all, I too am looking for a powerful curve tracer. Gona build me some amps in the future and a curve tracer is a must. I am glad erikovsky made me look for the Locky_z 2019 Curve tracer / Intelligent Curve Tracer. A good friend of mine is using this one for all of his builds, and prior to me locating this tracer on ebay, I would be dependent on him to match my MOSFETs.
While going over this thread I noticed the lack of two curve tracer projects that I find of interest, so figured I would share them and get some inputs. Do note that both of this projects needs to have the PCB's produced since they are not available.
Both of these projects are presented via Elektor.
Tracer #1:
This practical instrument can be used to measure and record the characteristic curves of NPN and PNP bipolar transistors, N- and P-channel JFETs, and N- and P-channel MOSFETs. The circuit is based on an R8C/13 microcontroller, which transfers the measurement data to a Windows application program via USB.

I have attached the Elector article published 02/2009.
Tracer #2:
By Rainer Schuster - This tracer is newer and more powerful. Can do both tubes and semiconductor, BJT, NPN/PNP and FET.
This versatile equipment can either be used as a power supply for tube experiments, or as a curve tracer. Originally, it was planned as a tube curve tracer, but during development, the idea came up to extend the functionality to a semiconductor curve tracer especially for high voltage transistors/ Mosfets and Zenerdiodes. It is controlled by a Raspberry Pi (model 2 or 3) together with a 7” touch screen. Voltage and current can be controlled via virtual potentiometers on the touch screen.
Actual voltages and currents are displayed via “7 segment displays” also located on the touch screen. The graphical user interface was designed wit Qt designer (see also Software).
MOSFET; Uds max 400V and Id to 300mA.
