Spectrum Analysers Explained

Spectrum analysers are used by a wide range of industries to measure the range of frequencies in a signal, among other things. They can be used to identify problems, measure waveforms, and much more. Spectrum analysers are considered to be the ‘workhorse’ for any electrical engineering and electronic troubleshooting. But what exactly is a spectrum analyser, how does it work and what can it be used for? This blog post will provide you with an overview of spectrum analysers and explain their importance in the fields of radio and electronics.

A spectrum analyser is used to measure frequency components of a signal or waves in the radio frequency (RF) range, or any frequency range. It’s really quite simple – the analyser takes in a signal or waveform and produces a graph showing the individual frequencies that make up the overall signal. This graph is called a frequency spectrum, and the way it is displayed can vary significantly between models and manufacturers.

Spectrum analysers are used for measuring the energy of a signal at any given frequency, for example to measure the power output of a microwave oven or the power output of a satellite transmitter. They can also be used for signal tracing and discovering where a signal is coming from. And due to their ability to measure large bandwidths, they are becoming increasingly important in the radio industry, particularly with the implementation of new technologies like LTE and 5G.

Spectrum analysers are also invaluable in evaluating the quality of a device’s performance. Using the power output measurement feature of the spectrum analyser, an engineer can make sure the device’s RF is continually operating at the expected level of performance. Additionally, engineers can measure the signal-to-noise ratio to ensure that the noise present in the signal is not excessively high.

Spectrum analysers are not only used in the radio and electronics industries. Oscilloscope manufacturers are increasingly utilizing spectrum analysis capabilities to detect, characterize and verify a variety of waveforms. This makes them invaluable for engineers tasked with debugging, testing and troubleshooting digital systems.

Spectrum analysers are critical for ensuring the successful operation of electronic systems. Whether used for measuring power output, signal-to-noise ratio, or waveform characterization, these analysers are increasingly becoming the go-to diagnostics tool in the radio and electronics industries.
