Definition: An instrument that is used for the analysis of the frequency spectrum of the input signal is known as a spectrum analyzer. It uses frequency domain representation of the RF signals in order to show the relative amplitude level of the signal at various frequencies within a …

2020年5月28日 · In this blog, I’ll go over the block diagram of a spectrum analyzer and describe a few important components of the equipment. Figure 1: A block diagram of a superheterodyne spectrum analyzer. Figure 1 shows a high-level block diagram of a classic superheterodyne spectrum analyzer.

2021年2月25日 · The Article Has Provided Information on Spectrum Analyzer Working Principle, Block Diagram, Working, Advanatages & Drawbacks and Applications

Most spectrum analyzers operate on the principle of “Heterodyne Wave Analyzer”. The Fig. 1 shows block diagram of a basic spectrum analyzer. The input signal is passed through an attenuator and then mixed in a mixer with a signal from a variable frequency (tunable) oscillator.

The basic block diagram (Fig. 9.13) is of a spectrum analyzer covering the range 500 kHz to 1 GHz, which is representative of a superheterodyne type. The input signal is fed into a mixer which is driven by a local oscillator.

Various local oscillators are used internally in spectrum analyzers. Residual response appears when the basic waveform and the harmonic components are mixed, producing the IF frequency. Residual responses appear in a specific frequency band, and the average noise level relates to all frequency bands. Residual response -100 dBm (f 0 =2 GHz band)
