SUMMARY
This discussion focuses on measuring and plotting the impedance of chokes across a frequency range of 30-40 kHz using specific equipment. Participants recommend utilizing an RL circuit configuration, employing a frequency generator, a variable power supply, and an oscilloscope with a spectrum analyzer. The method involves connecting the oscilloscope probes to measure voltage output and input, allowing for calculations of attenuation and phase shift to determine optimal resistor values for the inductor. This approach provides a clear pathway to accurately visualize impedance across the desired frequency range.
