The Rohde & Schwarz FSH8 is a handheld spectrum analyzer built for field deployment across 100 kHz to 8 GHz. Engineers use it for signal monitoring, interference hunting, cable and antenna testing, and network diagnostics. Its rugged, splash-proof construction supports extended battery operation while delivering laboratory-grade measurement accuracy in portable form.
