The Keysight / Agilent HP 89441A is a Vector Signal Analyzer covering baseband through RF frequencies of DC to 2.65 GHz. It offers robust scalar and vector analysis modes, enabling detailed time-domain characterization and demodulation. With a maximum vector analysis bandwidth of 7 MHz (selectable anywhere within the frequency range) and full-frequency scalar spans up to 2648 MHz, the instrument is designed to handle complex communications signals, including W-CDMA, digital radio, and digital video with optional measurement personalities. It captures both phase and amplitude characteristics in time-series data for advanced RF and baseband analysis.
