Q Meter Electronic Circuits and Diagrams Electronic ...
Circuit diagram of a Q meter is shown is figure. A wide range osÂcillator with frequency range from 50 kHz to 50 MHz is used as a power supply to the cirÂcuit. The output of the oscillator is shorted by a low value resistance, Rsh usually of the orÂder of 0.02 ohm. So it inÂtroduces almost no resistance into the oscillatory circuit and represents a voltage source with a very small ...Block Diagram & Working Of Q Meter (Sr No 26)

Figure 2 Q Meter Circuit Diagram. Test terminals 1 4 are to connect Lx and Cx. R13 (0.2 Ω) is five 1 Ω composition resistors in parallel. To Calibrate, set Sig Gen level for half scale on M1.Q Meter | Circuit Diagram | Factors of Q Meter | Impedance ...
Q Meter: The overall efficiency of coils and capacitors intended for RF applications is best evaluated using the Q value. The Q Meter is an instrument designed to measure some electrical properties of coils and capacitors.What is LCR Meter? Block diagram, Working and Use of ...
The above block diagram clearly defines the connection diagram of the LCR meter. The measurement of DC quantities will be done by exciting the bridge with DC voltage. On the contrary, the AC measurements require excitation of the Wheatstone bridge with AC signal.Q meter
A Q meter is a piece of equipment used in the testing of radio frequency circuits. It has been largely replaced in professional laboratories by other types of impedance measuring device, though it is still in use among radio amateurs.
