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 Storage Oscilloscope (DSO) and is transferred to a PC via an RS 232 Serial Interface, which may be in-built in some DSOs. Further, the software […]

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 of the signal versus time). This is the time domain. It is also useful to display signals in the frequency domain. The instrument providing this

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 of each harmonic or fundamental individually. This can be performed by instruments called wave analyzers. This is the simplest form of analysis in the frequency

Beat Frequency Oscillator (BFO) | Block Diagram | Working and Limitations: In this Beat Frequency Oscillator, the outputs of two RF oscillators are applied to a square law detector and the resulting difference frequency is amplified. The main advantage of this type of oscillator is that a stable continuous output covering the entire AF range

Digital Measurement of Frequency (Mains): Digital Measurement of Frequency (Mains) – The conventional method of measuring the frequency of an electrical signal consists of counting the number of cycles of the input electrical signal during a specified gate interval. The length of the gate interval decides the resolution of the Measurement. The shorter the gate

Working Principle of Digital Multimeter: Analog meters require no power supply, they give a better visual indication of changes and suffer less from electric noise and isolation problems. These meters are simple and inexpensive. Digital meters, on the other hand, offer high accuracy, have a high input impedance and are smaller in size. They gives
