The N9054EM0E VMA vector modulation analysis (VMA) measurement application is part of a library of more than 25 measurement applications used with the Keysight X-Series signal analyzers, an evolutionary approach to signal analysis that spans instrumentation, measurements and software. Transforming X-Series signal analyzers into vector modulation analysis mode, the application provides a wide range of measurements, demodulation types and filters to perform comprehensive signal analysis, helping you thoroughly test your designs, ensure product quality and optimize without compromise.
A powerful measurement combination:
- View detailed frequency behavior with over 400,000 frequency points FFT, meet the needs of the particular measurement from four different RBW filter shapes (Uniform/Hanning/Gaussian/Flat top). Use the x-axis scaling feature for a better view of the area of interest on your signal
- Dig deeper into signals in time domain with time gating and statistical power measurements (CCDF/CDF/PDF). Simultaneous time and frequency domain displays provide insight into signals that spectrum analyzers alone cannot deliver
- Implement customized modulation analysis from more than 30 demodulators including: 2 -16 FSK, PSK, and 16 -1024 QAM. Perform qualitative and quantitative signal analysis through flexible displays and markers
- Take the advantages of the familiar SCPI programmability, LAN/LXI connectivity and the speed of the Keysight X-Series signal analyzers, to link R&D design verification to production test racks
