What is vector signal analyzers?

A vector signal analyzer (VSA) is an instrument that measures the magnitude and phase of an input signal at a single frequency. It is commonly used for analyzing complex modulated signals, characterizing RF components, and troubleshooting wireless communication systems. VSAs can demodulate signals, perform spectrum analysis, and measure various signal parameters like error vector magnitude (EVM), adjacent channel power ratio (ACPR), and more.

spectrum analyzers

Spectrum analyzers are used to view the frequency content of a signal, similar to vector signal analyzers, but typically lack the ability to measure the phase information required for full signal demodulation and vector analysis. They primarily identify frequency components.

oscilloscopes

High-bandwidth oscilloscopes can capture and display signals in the time domain and, with appropriate software, can perform some of the same analysis as a vector signal analyzer, such as frequency domain analysis and demodulation. However, VSAs are generally more specialized and performant for RF signal analysis.
