The digital architecture that enabled the Fast Fourier Transform (FFT) analyzer ultimately led to true real time spectrum analysis (RTSA) with no sampling gaps or ‘blind spots’ in time. Technology has gradually evolved since the first swept-tuned analyzers emerged over 100 years ago. Programmable test routines, spectrum recording, and intuitive touchscreen displays are hallmarks of the latest generation of handheld instruments. Advanced digital technology enables a real-time spectrum analyzer to capture transient or elusive events. Common applications include radio frequency (RF) signal analysis, electronic circuit design and test, audio engineering, and fiber optic network activation and maintenance. Spectral components observed with a spectrum analyzer include the dominant frequency, harmonics, power, distortion, and noise floor. The frequencies and bandwidths of output signals can also be compared to the received input. A variety of products have been developed to evaluate a wide range of network and signal behavior. In the most general sense, it is a tool for measuring the power and frequency for known and unknown signals. A spectrum analyzer is a widely used test device that measures and plots signal power (amplitude) over a selected frequency range.
