Default Re: Measuring Resonant Frequency

A simpler way is to wind a two turn coil and connect your signal generator across that. Place it near the coil/cap you want to test. Make another two turn coil and connect to the scope and place this also near the circuit. These will not affect the resonant frequency very much and more important you will not be affecting the Q of your circuit so you should get a sharp maximum on the scope at resonance,
