I just got at little Peak measuring device. I was looking for something I could use for performing curve tracing without spending a lot of money. Just something simple. I ended up with this small device which has its limitation like only being able to measure at quite small currents (few mA). I think it is good enough for me and think I can learn a lot by using it. My hope is that I can match devices knowing that it will not be 100% perfect but probably better than random selection of devices.
The attached images shows a trace of a IRFP250.
Think it shows the "square law" relation between Vgs and Ids?
Just learned about that watching NP's lecture about Push Pull output stages. I must watch it again to get it all inside my head......lots of words…..
Think I understand why M2/M2X does not need matched output devices……
I was surprised of the quality of the Peak. The clips etc. are much better than usually cheap "junk". I also purchased a SOT23 probe so measurements of these small devices can be performed quite easy.
I was tool lazy building test rigs with 9V battery etc...….
