Re: Measurement challenge

A good exercise is to use your VNA to measure the very high unloaded Q of Toroid? coils.?I have good success with J. Oppenheimer's KN5L method for toroids with Q up to 230 using a single turn sense coil throigh the toroid connected to the VNA.? Above all the measurement's agreement with theoretical values for Q and phase shifts is a good check of your calibration.Accurate measurement of unloaded high Q is by no means trivial.?See? the link to his webpage below: from my Samsung Galaxy smartphone.

THE CALIBRATION BY WHATEVER METHOD YOU DESIRE IS NOW DONE. Complete. Now we desire to measure some components. We are now in a position to use the NanoVNA as a component analyzer. Go measure... Alan
