Question

How many types of analyzers or there?

Answer 1

An instrument that is used to analyze waves in the frequency domain is called a spectrum analyzer. This instrument is basically the energy distribution of a signal on a cathode ray tube screen. On the screen x-axis represents frequency and the y-axis represents the amplitude. The spectrum analyzer measures the spectrum content of the signal that is fed to the analyzer.

Complete step by step solution:
Spectrum analyzers are divided into two categories. The two types are a swept-tuned analyzer and a real-time analyzer.
A swept analyzer is a test instrument’s traditional form. They are also called analog spectrum analyzers. These swept-tuned analyzers are usually used for analyzing the signals that are in the RF range.
The real-time spectrum analyzer is used for analyzing the signals of the AF range. This real-time spectrum is also called a filter bank spectrum analyzer. The real-time analyzer will display the energy at all the frequency components simultaneously.

Additional Information:
It has numerous advantages. The advantages are it can measure the spectral quantity of the signal on the radio frequency range. It also can provide several measurements. This only has one disadvantage. The disadvantage of the analyzers is their cost, which is quite higher when compared to the usual conventional meters.

Note:
A spectrum analyzer has applications that are used to measure a variety of quantities. Frequently measured quantities using a spectrum analyzer are signal levels, phase noise, harmonic distortion, intermodulation distortion, and spurious signals. The working of the spectrum analyzer can be categorized as producing a horizontal and vertical sweep of the measured signal. This measured signal would be with respect to frequency and the vertical sweep would be with respect to its amplitude.
