The R&S®FSW67 provides direct, native frequency coverage from 2 Hz to 67 GHz without requiring external mixers. With optional R&S external harmonic mixer modules, frequency coverage can be extended up to 110 GHz, 325 GHz, and even 1.1 THz.
Yes. By equipping the analyzer with the optional R&S®FSW-K60 module, the instrument activates real-time spectrum analysis with bandwidth capabilities up to 250 MHz (and up to 800 MHz depending on system configuration), enabling minimum event detection times shorter than 1 µs.
The instrument comes standard with up to 100 MHz analysis bandwidth for baseband I/Q capture. It can be expanded up to 1.5 GHz using the R&S®FSW-K106 IF bandwidth module and offers up to 8.3 GHz internal analysis bandwidth.
The analyzer supports a wide spectrum of standards including 5G NR (via the R&S®FSW-K100 module), 4G LTE/LTE-A, Wi-Fi 6/6E, DVB-S2X, Bluetooth, custom digital modulations, and satellite communications (via R&S®FSW-K70).
Yes, automated testing is fully supported through standard GPIB, Gigabit LAN (LXI Class C compliant), and USB 3.0 interfaces. Test engineers can leverage SCPI recorder features and R&S®VISA software for simplified test code generation and unattended production line deployment.
No, the R&S®FSW67 operates without internal batteries. It is designed for standard AC mains power in laboratory, benchtop, or standard 19-inch rack-mount environments.
