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…
Spectrum Analyzer Block Diagram: Spectrum Analyzer Block Diagram - The most common way of observing signals is to display them on an oscilloscope, with time as the X-axis (i.e. amplitude…
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…
Heterodyne Wave Analyzer: Wave analyzers are useful for measurement in the audio frequency range only. For measurements in the RF range and above (MHz range), an ordinary wave analyzer cannot…
Frequency Selective Wave Analyzer: The Frequency Selective Wave Analyzer consists of a very narrow pass-band filter section which can be tuned to a particular frequency within the audible frequency range…
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…
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…
Video Test Pattern Generator: A pattern generator provides video signals directly, and with RF modulation, on standard TV channels for alignment, testing and servicing of TV receivers. The output signal…
