Offering touchscreen operation, R&S FSW85 enables users to test baseband and RF with one analyzer. No external harmonic mixers are required, which facilitates test setup, and internal preselection suppresses image frequency and other spurious emissions that typically occur during harmonic mixing. Optionally, instrument can be equipped with internal analysis bandwidth of 500 MHz. When combined R&S FSW-B2000 option and R&S RTO oscilloscope, analysis bandwidth of 2 GHz can be achieved.
