Work as claimed. Documentation needs to be polished a bit.
For AD2™ Curve Tracer add-on board
Delivery ok.
Needs to be soldered by end customer upon delivery to work (was indicated at the beginning, just a reminder).
Waveforms interface works right away, but the stupid XY window is always inverted and descaled. After every scan needs to be recropped.
Therefore, "Option B" dedicated software is advised.
Installation takes 10-20 minutes to try this-and-that but later it works. (I got Win10 64bit)
Pinout should be a picture. Manual have phrase "Use the row furthest from the board-to-board connection header and closest to the edge of the board." = impossible to understand by low-iq individuals.
Curves on my KT315 transistor looks blurred but maybe it should be like that.
~20$ is a good price-to-value offer to have custom Curve Tracer thing.
Thanks Ilya.
