The q of a coil is independent of frequency
Webb8 maj 2016 · The Q factor can have a value between 0 and infinity, although it is difficult to obtain values far above 1000 for coils. For mass production we may expect values … WebbOn a high Q air core coil the cro trace will quickly indicate resonance when manually sweeping the generator. Move the generator off frequency to find where the amplitude is 70% down. This is a measurement of Q. A large freq differance is indicative of low Q. The maximum amplitude scope display directly gives a feel for Q.
