VSA (Vector Signal Analyzer) digital demodulation is used to analyze and decode digitally modulated signals in communication systems. This process helps engineers assess the quality of the transmitted signal by breaking it down into its in-phase (I) and quadrature (Q) components and comparing the received signal against the ideal modulation scheme (e.g., QPSK, QAM).
Digital demodulation with a VSA allows for the measurement of critical performance metrics like error vector magnitude (EVM), symbol errors, phase and amplitude distortion, and signal-to-noise ratio (SNR). It is used to diagnose and correct issues such as interference, signal degradation, and hardware imperfections, ensuring that communication systems (e.g., LTE, Wi-Fi, 5G) meet their performance standards and deliver reliable signal integrity.
With the UNI-T UTS3000A Signal Analyzer UTS3000A-VSA option enabled, users can perform simple and complex analysis of digitally modulated signals. The UTS3000A can provide S11 and S21 parameter information on two-port networks.
