I know this is really basic but I am having trouble configuring the settings on the tracer module for a KSA992 PNP transistor. I obviously need to learn more about the difference in how an NPN and PNP transistors work, but if someone could get me started with an example I would be really grateful. The examples provided in the Guide are for an NPN and I can't figure out how to set the software up for a PNP transistor. I need to match a group of KSA992 PNP transistors and cannot figure out how to set it up so I can calculate the Hfe. I have the datasheet on the KSA992 and know the gain range, but I am trying to match a pair. I have not been able to figure out which numbers to use to set up the curve tracer ranges. I am using a Digilent Analog Discovery 2 with the Digilent adapter. Thanks ahead of time for any guidance.

That is it for now, I am trying to improve my ability to measure THD on my amplifiers. I find that if I use a straight BNC connector to both outputs of my Class D audio amplifier it will shut down the output transistors since they don't like a common ground. I found a workaround by either using differential probes or just not grounding the amplifier output side of the probe. I feel that a Breakout adapter would allow for experimentation. Since you are kind enough to ask for requests, I have one for the software side. If you could add a measure to the THD function, it would provide a functionality not available right now on any other scope I am aware of. Right now I see a visual representation of the THD or THD+Noise in the Network tab, it would be really nice to be able to get a specific number just like we can for frequency, voltage, etc. I assume getting an average would be the simplest and should work, but ideally you would be able to click on any point on the graph and get the measure.

I was trying to purchase additional ribbon cables, and Breadboard Breakout 't like the one for the Analog Discovery pro. However, it appears you don't have 12 pin ribbon cables or breakout boards. Will some of these accessories be available for the ADP series?
