Spectrum Analyzer- An important device of telecommunication

Spectrum analyzer- It's a big scientific name or technical word for a layman. But it's the most basic electronic device for many industries and fields. It is used in military, aerospace, oil industries, telecommunication fields, movement of ships, and various other research industries. Today we are using the microwave, audio, optical and wireless technologies. Most importantly, we can't think our life without them and all these technologies are using some or any other kind of spectrum analyzers. As there are various types of spectrum analyzers.

History of Spectrum analyzers- In the mid 19th century,  the idea of spectrum analyzer was just like a fiction made by the science. People think this as a fiction since invention and discovery of electric and magnetic waves. After that in 1865, James Clerk Maxwell gives the idea and full flashed theory of Electromagnetic Field. This theory explains correctly and detailed idea of the behavior of natural electrical and magnetic waves that are moving through the airwaves at the speed of light and regarding radio waves. To measure these radio frequencies, RF spectrum analyzers came into existence.

The theory described by the Maxwell was a giant superhighway that was in the sky, but there was no practical evidence. But in 1885, a famous scientist named Heinrich Hertz give proved that it's possible to send or receive electrical waves wirelessly. This is the reason the frequency unit of measure was named after him.

To measure those received and transmitted signals, oscillator was developed to track the signals. One was that can only measure the signal voltage in the time domain by visually plotting the waves on a small CRT display. This electronic device was excellent but there was a need for strong and more innovative ideas to continue the technological evolution. The spectrum analyzer was developed in early 1960's. The spectrum analyzer was introduced before more than 50 years and the technology, functionality, and applications of spectrum analyzer have continued to improve.  

Nowadays, the usage of Wi-Fi and the cell phone has been increased, so there is always a need for accurate and sound quality of service. As in telecommunication, spectrum analyzers are used to determine the spectrum of the signals and frequency utilization, and interference issues in a specific region.
