Despite advancements in internal design and component performance, these ultra-compact units are not typically required to be high performance tools and so are limited with respect to feature sets, frequency range, and accuracy. Compact spectrum analyzers are often ruggedized, incorporating features such as screen glare reduction, weather-proofing, and integrated handles.Ī new class of small spectrum analyzer that can fit in the palm of your hand has become a reality. A portable spectrum analyzer is usually battery operated or rechargeable, under 15 lbs., and optimized for use in the field. A full spectrum analyzer in the lab is frequently used in conjunction with an oscilloscope or other high-end equipment.Īs the number of applications multiply, portability and durability gain importance. The benefits and features of benchtop models include higher computing power and available real estate for modules, ports, knobs, buttons, and displays. For each specific application, VIAVI has developed a breadth of solutions to support test, maintenance, and troubleshooting activities.ĪC-powered analyzers for lab and manufacturing environments are typically designed for a standard 19” rack or tabletop installation for larger equipment. The form factors and types of spectrum analyzer now available include every conceivable size, shape, and complexity level. 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.
