Rohde & Schwarz Microwave preselector bypass for wide analysis bandwidths at center frequency > 7.5 GHz (software license)
The R&S®FSW-K18 is a software license option for the R&S®FSW signal and spectrum analyzer series, enabling the microwave preselector bypass functionality for analysis bandwidths at center frequencies above 7.5 GHz. This feature allows users to bypass the internal preselector, which is beneficial for applications requiring wide analysis bandwidths and minimal signal distortion, such as wideband signal analysis and advanced research. The bypass function is particularly useful for measurements where the preselector's filtering could limit the analyzer's performance or introduce unwanted effects. The license is delivered electronically and is activated via a key code, ensuring seamless integration with compatible R&S®FSW analyzers. This option is essential for users who need to analyze signals with bandwidths that exceed the limitations imposed by the preselector, providing greater flexibility and measurement accuracy in demanding test environments.
