Rohde & Schwarz FSH6 100KHz – 6GHz Spectrum Analyzer

The Rohde & Schwarz FSH6 is a handheld spectrum analyzer delivering field-ready performance across 100 kHz to 6 GHz. Built on super-heterodyne receiver architecture, It has signal strength measurements with displayed average noise level of typically −135 dBm (100 Hz RBW) and level accuracy of typically 0.5 dB across its full frequency span. The instrument combines portability with essential analysis capabilities for spectrum monitoring, signal identification, and antenna/cable characterization.
