Hi,
Can anyone explain why my Tektronix shows double curves in each step when I testing transistors?
thank you!

It’s the effect of internal capacitance in the device and/or heating/cooling of the semiconductor junction.

I remember frying some diodes during lunch on a brand new 575 in a class. Teacher walked by and said what are you doing? I and classmate said burning up some diodes. Good, good, he said, knowing we were learning. Try some sacrificial junctions. Turn up the drive and see huge loops from the heating.
