Thanks for the reply but I don't think you addressed my questions. I'm not using the adapter. And it's strange, my GUI showed the settings next to Vrc affect the base drive (in your image 0V to 4V) and settings next to Vrb affect collector voltage (in your image 700mV to 1.5V). The boxes on top ought to be swapped with the bottom boxes.
Also, mouse scrolling is very wonky when I try to go up/down within these boxes. For example, if -1V is selected and I scroll, the value jumps to -5V and then to -4.5V, but it doesn't allow lower values. If I select the pulldown, I can select -2V or -1V again, but scrolling doesn't work. I think the Tracer defaults to Auto mode, so that might be interfering. I'm curve tracing a PNP. EDIT: It doesn't matter whether NPN or PNP, and It doesn't matter if it's running or stopped. I noticed that when I pull down to see all the values, it jumps to the most negative value in the list. EDIT: Never mind, I selected the wrong polarity (PNP vs NPN).
