You can also probe the current in a wire. To do this, hold down the Alt key and click on the wire. V(n001,n002)是这两个网络的电压差 You can measure differences in this manner without performing the zoom by either pressing the Esc key Whenever a waveform plotting window is the active...
It doesn't seem feasible to build the board just to try to measure those really small LCR values and then simulate it after the fact. Do PCB manufacturers provide that information in some way like all the other component manufacturers do? (Isn't a PCB a component in the end?) Logged ...
1. Drag a box about the region you wish to measure Hold the left click down 2. View the lower left hand side of the screen 3. Shrink your box before you let go of the left mouse click or use the undo command on top to resize ...
The idea here is that the bottom left photo-diode is inserted into the transmitter's feedback loop. This causes the transmitter op-amp output to adjust the current through U4's LED (top) so that the required current is fed back from the left photo-diode. The lower right photo-d...
Mouse over a resistor and left click. The current is displayed. Notice the scale changes automatically. Double clicking anywhere you want to measure brings just that one value into focus with just that trace displaying. What about RMS voltages ? We know we have 1 volt peak which equates ...
