A Basic Introduction to Grid Dip Meter The Grid Dip Meter (GDM) or the Grid Dip Oscillator (GDO) is an electronic instrument used in measurement and testing of radio frequency circuits. It is basically an oscillator with an exposed coil and oscillation amplitude readout. It has three main functions: Measuring the resonant frequency of an LC resonant circuit, a Crystal/Ceramic resonator, or an Antenna,… |
