The R&S FSW85 is the latest addition to Rohde & Schwarz’ family of signal and spectrum analyzers. It is the only device on the market designed to cover the frequency range from 2 Hz to 85 GHz in a single sweep, allowing users to test baseband and RF with a single analyzer. Test setups are now much simpler, since the R&S FSW85 does not require harmonic mixers. An internal preselection feature suppresses the image frequency and other spurious emissions that commonly occur during harmonic mixing.
