I understand what is meant by clicking on a node, but I thought the 'net' was the whole circuit? I loaded another entirely different .asc file that I have for a much simpler HV generator circuit that operates from 3-5vDC. I have reverse engineered a CFL lamp driver board in order to better understand how it works. I used that method with only the circuit diagram open and saw 0v at my probed point on the diagram. If you need to plot a differential voltage, move the mouse to the positive node of the voltage to be measured and once the probe symbol has appeared, left click the mouse then drag the probe to the negative node. Adding parts to TINA is pretty easy. EE 105 - LTSpice Page 2 Plotting the Voltage Gain Use expressions to plot the voltage gain of the circuit. LTSpice is a versatile, accurate and free circuit simulator available for Windows and Mac. Going back to the CFL driver circuit I had uploaded, I did notice an error with the two inductor coils, L3 and L4, which were polarised in opposition direction to each other so that their effects would have effectively canceled each other out. You can edit the label of the x axis to say anything you want.
