The Rohde & Schwarz FSH is a rugged, handheld spectrum analyzer designed for field applications. Offered in multiple variants ranging up to 20 GHz, it is highly configurable for tasks such as installation and maintenance of transmitter stations, cable and antenna measurements, and interference hunting. Its versatile design allows integration of a tracking generator, VSWR bridge, and preamplifier depending on the specific model and options selected.
