Spectrum Analysers

About Spectrum Analysers

A spectrum analyser displays a spectrum of signal amplitudes on different frequencies. It enables analysis that determines whether signals fall within the required limits. It displays spurious signals, complex waveforms, rare short-duration events, and noise.

Spectrum analysers can also analyse transient signals, capture burst transmissions and glitches, and show if stronger signals are masking weaker ones.

The devices are frequently used to examine the dynamic frequency spectrum of modern RF and audio signals that change over time. They display the individual elements of signals and the performance of the circuits producing them.
