The Rohde & Schwarz FSH18 is a handheld spectrum analyzer for field and laboratory signal analysis across 10 MHz to 18 GHz. Weighing 2.5 kg with a transflective color display, it delivers measurement accuracy to ±1.5 dB up to 6 GHz and operates up to 3 hours on internal battery. The FSH18 excels in mobile base station commissioning, RF cable diagnostics, and microwave measurements, offering multiple detector modes, channel power analysis for digital standards, and optional receiver functionality for EMC pre-qualification work.
