Hi @attila, ah right, thanks for explaining that! That makes sense.

Hi @attila, thanks for your reply. I understand that this changes the range of voltages that can be applied at the collector, but am wondering whether this is actually electrically isolated from the base - reading the documentation, the implication is that the emitter voltage is offset, which would then change the base-emitter voltage (and thus the base current), but this doesn't seem to be the case. Is it the case that the virtual ground applied here is only for the collector connection, and that this is isolated from the base-emitter node?

Hi there, I'm using the Analog Discovery 3 in conjunction with the transistor tester add-on board to profile a selection of transistors. I notice that one of the options apparently sets the emitter voltage, but it is unclear whether this actually sets the voltage at the emitter. When tested using a 2N3904, the base current is consistent with a Vbe of ~0.75V, and an emitter at ground - regardless of the emitter setting. Could you please clarify what the emitter setting actually does in the tracer settings? Thanks!
