Rohde & Schwarz FSW43

This used Rohde & Schwarz FSW43 signal and spectrum analyzer extends frequency coverage up to 43.5 GHz, making it a capable tool for engineers working on millimeter wave and broadband RF applications. Pulled from an active test environment, this unit has been kept in good working order and is ready to support demanding signal analysis tasks in a new lab or production setting. It represents a cost effective way to acquire high frequency analysis capability that would otherwise require a significant new equipment investment. The FSW43 delivers wide analysis bandwidth, low noise floor, and fast measurement speed suited to complex modulation analysis, 5G and satellite communication testing, and radar signal characterization. Its flexible architecture supports a broad range of measurement applications, including phase noise, pulse, and vector signal analysis, giving engineers the tools needed to fully characterize modern wideband signals. This makes the instrument valuable in both R&D and production test settings where accuracy and repeatability are critical. Labs and manufacturers working with high frequency and wideband signals will find this a dependable addition to their test equipment lineup. It is well suited for telecom, aerospace, and defense applications requiring precise signal analysis. As with any used instrument, we recommend verifying calibration status and requesting service history to confirm it meets your specific measurement requirements.
