Rohde & Schwarz Spectrum Analyzer Preamplifier (software license)
The Rohde & Schwarz FSV-K30 (part number 1321.0680.02) is a software license option that enables the preamplifier function on the R&S FSV and FSVA spectrum analyzers. This preamplifier option improves the analyzer's sensitivity by reducing the displayed average noise level (DANL), making it possible to measure very low-level signals with greater accuracy. The FSV-K30 is activated via a software key and does not require additional hardware installation. It is designed for applications where detecting weak signals is critical, such as EMI debugging, wireless communications, and research and development. The preamplifier function can be toggled on or off as needed, providing flexibility for various measurement scenarios.
