- Other than using the sales / technical literature, how can I measure the resistance of ferritecore or beads to ensure that I have the recommended 5000 ohms resistance? I gather that the resistance is

- If you have a R/X meter or VNA or antenna analyzer or similar.. you can wind a few turns of wire through the core and measure the R and X vs frequency. Jim's RFI-Ham pdf has some examples. in as many

- Bob, Even the technical literature wont give you a complete picture because it wont take account of the stray capacitance introduced by the choke winding. The most effective technique I've found is o
