The new R&S FSW85 high-end signal and spectrum analyzer is the only instrument on the market to cover the frequency range from 2 Hz to 85 GHz in a single sweep. This makes it possible for users to test baseband and RF with a single analyzer. Since no external harmonic mixers are required, the R&S FSW85 makes the test setup much simpler. An internal preselection suppresses the image frequency and other spurious emissions that commonly occur during harmonic mixing.

The R&S FSW85 can be optionally equipped with an internal analysis bandwidth of 500 MHz, giving developers of radar components a variety of analysis options ‒ particularly for automotive and aerospace and defense applications. When combined with the R&S FSW-B2000 option and an R&S RTO oscilloscope, it is even possible to achieve an analysis bandwidth of 2 GHz, allowing developers to analyze broadband signals for 5G next-generation mobile communications signals or complex pulse parameters and chirp signals for radar systems.

The R&S FSW85 offers easy touchscreen operation with clear diagrams and a flat menu structure. Various measurements can be displayed simultaneously in separate windows on the large 31 cm screen to simplify interpretation of results.
