Modern Spectrum analyzers are complex electronic devices used in various applications to measure and analyze characteristics of RF signals. Here we will see what are spectrum analyzers, block diagram, specifications, and applications of spectrum analyzers.

RF Spectrum Analyzers are electronic devices primarily used for measuring the RF (radio frequency) spectrum and the communications signals emitted by various types of electronic devices. This is usually done by using a wideband receiver and a calibrated transmitter. The RF spectrum analyzer is able to measure the frequency of the radio waves and their amplitude or power.
