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,… |

Capacitor ESR Meter using Oscilloscope Capacitors seem all fine till you get to the point where a power supply fails or refuses to perform optimally. And if the problem is noise, there is a simple fix, you just add more capacitors. But that does not solve it. What could be wrong? The problem arises from the naïve assumption that capacitors (to a large extent) are ‘ideal’ devices, while… |

How to measure value of Inductor or Capacitor using Oscilloscope – Resonant Frequency Method Resistors, Inductors and Capacitors are the most commonly used passive components in almost every electronics circuit. Out of these three the value of resistors and capacitors are commonly marked on top of it either as resistor colour code or as numeric marking. Also the resistance and capacitance can also be measured using normal Multimeter. But most of the inductors,… |

Capacitance Meter using Arduino When we come across circuit boards which are previously designed or we take out one from old TV or computer, in attempt to repair it. And sometimes we need to know the capacitance of particular capacitor in the board to eliminate the fault. Then we face a problem in getting the exact value of capacitor from the board especially if it is a Surface Mount Device. We can buy… |
