Hi, I am asked to find a method to find i vs v characteristics, using a digital oscilloscope. As a hint, it is said that I should connect a resistor of 1kohm between the signal generator and the terminal a to observe i in mA.
I think that I should connect a floating signal generator and a 1kohm resistor in series between the terminals a and b. Then I can connect Channel1 to b, Channel2 to positive terminal of the signal generator and Ground Probe of DSO to terminal a. Then inverting both channels in XY mode should give me i vs v characteristics. But I couldn't find the an expression of voltage V'(t) that the signal generator must give to circuit as a function of V(t), in order to obtain V(t) between the terminals a and b.
