Rohde & Schwarz Phase coherent input and output (software license)
The R&S®FSW-K18 Phase Coherent Input and Output software license enables phase-coherent signal acquisition and generation on the R&S®FSW signal and spectrum analyzer. This option allows users to synchronize the analyzers input and output paths, making it possible to perform advanced measurements such as phase-coherent signal analysis, MIMO testing, and other applications requiring precise phase relationships. The license is installed via a key code and is compatible with supported R&S®FSW models. It is designed for users who need to perform measurements where phase coherence between input and output is critical, such as in radar, communications, and research applications.
