Basics of spectrum analyzers and RF measurements

Step-by-step guides to mastering the fundamentals

The spectrum analyzer is an invaluable tool for troubleshooting and optimizing electronic systems! It allows the user to visualize and measure the amplitude of different frequency components within a given signal. Its key feature is displaying the signal amplitude versus frequency in a graphical format. Users can identify frequency peaks, signal harmonics and interference patterns.

These articles will walk you through the fundamentals of spectrum analyzers, along with related applications. From understanding spectrum analyzer operation to learning the basics of RF measurements, we are your go-to resource for mastering spectrum analyzers.
