Megger Circuit Diagram: Another common method of measuring resistances above 50 M Ω is the Megger Circuit Diagram (megaohmmeter) shown in Fig. 10.23(a). This instrument is used to measure very…
Automatic Bridge Circuit: The bridges discussed so far require that the controls be adjusted for balance after each capacitor (or other devices being tested) is connected to the bridge. In…
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…
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),…
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…
FFT Spectrum Analyzer Using a Waveform Processing Software(SS-36): FFT Spectrum Analyzer - The Waveform Processing Software (SS-36) enables one to analyze waveforms very easily. The waveform is captured on a Digital…
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…
Circuit Connections for Producing a Vectrogram and Lissajous Pattern: This test instrument combines a keyed colour bar generator with an oscilloscope and is used for alignment and testing the colour…
