The 89440A vector signal analyzer cover baseband through RF frequencies of dc to 1.8 GHz, in scalar and vector analysis modes. The scalar RF instrument mode allows full-frequency coverage in spans of 1798 MHz. Vector RF mode offers exceptional speed and additional signal processing for enhanced time-domain characterization and demodulation. Vector spans as wide as 7 MHz can be selected anywhere in the 1.8 GHz 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 anaysis, AM/FM/PM demodulation, time-selective analysis, and may other types of mesurements.
