I was fortunate enough to score a small handful of these devices.

Enjoy the pictures.

Would you be kind enough to do one of the second also for the F3 current range ?
Curve taken at room temperature, in pulse mode, without heat sinking ?

Will do. I have to reconfigure the equipment stack for that.

For the moment, what I am doing to fake out pulse mode is to make NPLC small. I have gone down to 0.05 NPLC which is 834 uS. Reducing points on the curve also reduces total energy. If I end up writing my own software some day, I will have a place to limit total energy per unit of time; duty cycle if you will, to approach isothermal.
 
Vgs -2.3v to -1.1v in 8 equal steps. The wonky shaped curves are an interaction of the sourcemeter with the device. I tried about 20 different things none of which cured the problem. I will re-visit when I can.

Current limit was set at 1.8A
