This video demonstrates how to measure impedance from 10Hz to 10MHz using a Tektronix P6042 Current Probe, Siglent SDS1104X-E Oscilloscope with Bode Plot II, and a Siglent SDG2042X function generator. I show examples of impedance plots of resistors, inductors, speakers, and standard and polarized capacitors. The results are good from 10Hz through 1MHz and usable to 10Mhz. The speaker impedance measurement shows how the impedance and resonant point of the peak changes with it's physical location.
