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…
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…
Harmonic Distortion Analyzer: A Harmonic Distortion Analyzer measures the total harmonic power present in the test wave rather than the distortion caused by each component. The simplest method is to…
What is Wave Analyzer?: It can be shown mathematically that any complex waveform is made up of a fundamental and its harmonics. It is often desired to measure the amplitude…
Function Generator Block Diagram: A Function Generator Block Diagram produces different waveforms of adjustable frequency. The common output waveforms are the sine, square, triangular and sawtooth waves. The frequency may…
Dual Trace Oscilloscope: Figure 7.19 (a) shows a block diagram of Dual Trace Oscilloscope. This CRO has a single electron gun whose electron beam is split into two by an…
DC Standard Differential Voltmeter: A basic DC Standard Differential Voltmeter can be operated in different modes. The three basic modes of operation are as a dc voltage standard, as a…
DC Meter: The most commonly used dc meter is based on the fundamental principle of the motor. The motor action is produced by the flow of a small amount of…
