electronics-notes.com: Dip Meter: Grid Dip Oscillator GDOArkiveret 8. juli 2017 hos Wayback Machine Citat: "...Essentially the dip meter or GDO is a very simple instrument, but one that can give a considerable degree of insight into various aspects of the performance of radio frequency circuits and elements...How to use a dip meter GDO...As a rough rule of thumb, it is best to move the two coils away from each other so that the dip is around 25% of the maximum meter reading. This gives a sufficiently large dip to be seen and locate the bottom of the dip, whilst also keeping the coupling to a minimum...How to measure inductance with a dip meter...How to measure capacitance with a grid dip meter / oscillator..."

The resonant frequency of the external circuit can then be read from the calibrated dial of the grid-dip oscillator..."
