Rohde & Schwarz RF OFF for all ports after instrument boot up (software license)
The R&S®FSW-K-B1 RF OFF for all ports after instrument boot up (software license), part number 1332.5736.02, is an official software option for the R&S®FSW signal and spectrum analyzer series. This license ensures that, upon instrument startup, all RF ports remain deactivated (RF OFF) until the user manually enables them. This feature is designed to enhance operational safety and prevent unintended RF emissions or signal interference during the analyzer's initialization phase. The license is delivered electronically and is activated via a key code, integrating seamlessly with the instrument's firmware. It is particularly useful in environments where strict RF emission control is required, such as shared laboratory spaces or sensitive measurement setups. The option is compatible only with supported R&S®FSW models and requires a valid base unit for activation.
