RX Meter Circuit in Measuring Instruments: An RX Meter Circuit in Measuring Instruments is used to measure the separate resistive and reactive components of a parallel Z network. It is especially useful in the design…

LCR Bridge: Basic LCR Bridge (Skeleton Type) : A simple bridge for the measurement of resistance, capacitance and inductance may be constructed with four resistance decades in one arm, and binding post terminals to which…

Q Meter: The overall efficiency of coils and capacitors intended for RF applications is best evaluated using the Q value. The Q Meter is used to measure some electrical properties of coils and capacitors. The…

Vector Impedance Meter (Direct Reading): If some knowledge of the reactive and resistive factors is needed, in addition to obtaining a direct reading of the magnitude of the impedance (Z), a test method for determining…

What is Phase Sensitive Detector or Phase Meter Circuit?: Figure 10.4 shows a Phase Sensitive Detector or Phase Meter Circuit for comparing an ac, signal with a reference signal. The Phase Sensitive Detector Circuit produces…

Stroboscope Working Principle: The stroboscope working principle uses a high intensity light which flashes at precise intervals. This light may be directed upon a rotating or vibrating object. The stroboscopic effect is apparent when the…

Field Strength Meter (Transistor) Circuit: The Field Strength Meter is used to measure the radiation intensity from a transmitting antenna at a given location. With its own small antenna, it is essentially a simple receiver…

Output Power Meter Working Principle: The Output Power Meter Working Principle is designed to directly measure the output power in an arbitrary load. The instrument provides a set of resistive loads to be selected for…
