Signal analysis capabilities in a portable RF spectrum analyzer are essential for 5G and LTE modulation analysis, channel mapping, and conformance testing to 3GPP standards.

Signal Analysis has developed as an offshoot of RF spectrum analysis to provide detailed information on the amplitude and phase relationships between signals and their modulation characteristics.

Along with automated workflows, cloud connectivity, and vastly simplified reporting, these advanced features address the evolving needs of RF service providers, field technicians, and contractors.

The real-time spectrum analysis (RTSA) technology developed by VIAVI provides a foundation for a host of new portable RF analysis features. Despite these advancements, the RF spectrum analyzer remains the best option for verifying and troubleshooting RF performance from the concept phase to the field. Duplexing and multiplexing options squeeze more bandwidth out of airwaves and fiber while mmWave shifts frequency allocation closer to the edges of the RF spectrum poster. The wireless revolution has driven higher RF spectrum utilization and channel density, along with more interference sources. Modern RF spectrum analyzers also provide detailed insight into channel utilization, signal phase, and modulation properties. The display convention for RF spectrum analysis has remained virtually unchanged, with the radio frequency visible on the x (horizontal) axis and the signal power (amplitude) plotted using a logarithmic scale on the y-axis.

Although spectrum analysis equipment and technology has been adapted for optical, audio, and other applications, the radio frequency spectrum analyser was developed specifically to characterize RF signal behavior over a given frequency range.
