The 89440A Vector Signal Analyzer covers baseband through RF frequencies of dc to 1.8GHz, in scalar and vector analysis modes. The scalar RF instrument mode allows full-frequency coverage in spans of 1798MHz. Vector RF mode offers exceptional speed and additional signal processing for enhanced time-domain characterization and demodulation. Vector spans as wide as 7MHz can be selected anywhere in the 1.8GHz frequency range. In vector RF mode, both phase and amplitude characteristics are captured in the time-series data. This information can be processed for narrow resolution spectrum analysis, AM/FM/PM demodulation, time-selective analysis, and may other types of mesurements.
