Basic Spectrum Analyzer Block Diagram

Basic spectrum analyzer block diagram. It can be seen from the block diagram that the horizontal deflection is obtained from a saw tooth wave generator. Basic spectrum analyzer using swept receiver design. Referring to the block diagram of fig. The block diagram of a spectrum analyzer of swept frequency type is shown in figure.

It consists of a primary detector which is a simple lc circuit. The above figure shows a simplified block diagram of a spectrum analyzer. The output of the saw tooth wave controls the frequency of the voltage controlled oscillator also called the voltage tuned oscillator. Such analysis is provided by a wave analyzer distortion analyzer spectrum analyzer and digital fourier analyzer.

A basic wave analyzer is shown in fig. 9 9 b the sawtooth generator provides the sawtooth voltage which drives the horizontal axis element of the scope and this sawtooth voltage is frequency controlled element of the voltage tuned oscillator. In this video i have explained spectrum analyzer block diagram basics and working with following outlines. Although the basic concept of the spectrum analyzer is exactly the same as the superheterodyne radio the particular implementation differs slightly to enable it to perform is function.

It is one of the most used frequency measurement tools. Spectrum analyzer basics 2. Superheterodyne or swept frequency spectrum analyzer block diagram. Block diagram of basic wave analyzer.

In contrast a real time spectrum analyzer rtsa provides the same basic functionality as a traditional swept tuned superheterodyne spectrum analyzer but with a number of added benefits. Block diagram of spectrum analyzer. Normally for rf or microwave signal analysis the swept technique is preferred. Till now we have discussed the basic introduction of the spectrum analyzer.

Block diagram the basic msa the spectrum analyzer the msa with tracking generator the vector network analyzer system analysis msa gain input sensitivity maximum input power level input dynamic range msa input noise floor other factors affecting analysis module analysis local oscillator output levels and mixer drive control board using slim cb. Figure 2 shows a block diagram of a basic rtsa.
