Components of Q Meter
Here are the common components of Q Meter:
- Meter: The Quality factor meter has a simple meter to measure the ratio of voltage and current and help to measures the quality factor of the following circuit.
- Coupling Coil: It is also a important component of Q meter. It is used to give energy to the meter between circuit being tested. It also measures the quality factor by transferring sufficient energy between them.
- Detector: It is also a part of Q meter that is used to measure the quality factor across the circuit being tested and also measure the voltage across the circuit.
- Tunable Oscillator: It is used to produce the signals or frequency for the circuit and compare with the frequency of circuit that tested.
- Capacitor: It plays a crucial role to store and release the energy for circuit that tested.
- Q-Scale: It is a important measurement scale that used in Q meter, it is used to determine the quality factor of the circuit that tested. It gives a numerical value that tells the efficiency or power of the circuit.
Q Meter
It is an electronic device used in communication like telecommunication in hardware and electronics to determine or calculate the value of the quality factor of the electrical system. It is also used in electric capacitors to measure the value of capacitance and in inductors to calculate the value of inductance. It works and runs on the principle of resonance. When the circuit is in the condition of resonance, the circuit’s impedance becomes resistive. It also measures or calculates the reactance of many unknown circuits by using the known reactance. It is also known as the Quality Factor Meter.
