Rohde & Schwarz FSH20 20GHz Handheld Spectrum Analyzer

Rohde & Schwarz FSH20 20GHz Handheld Spectrum Analyzer

The Rohde & Schwarz FSH20 20 GHz Handheld Spectrum Analyzer is a portable test instrument that measures radio-frequency and microwave signals from 9 kHz to 20 GHz. It allows technicians to examine signals at installation sites, in maintenance facilities, and in the field, supporting work on communications and other RF equipment.

The FSH20 displays signal amplitude against frequency, helping users see where signals occur and how strong they are. This makes it useful for checking transmitter output, examining unwanted emissions, and investigating interference. Its broad frequency coverage allows measurements across many radio and microwave bands.

A built-in preamplifier improves sensitivity when measuring weak signals. With suitable measurement settings, it helps technicians distinguish low-level signals from background noise. Optional software applications expand its capabilities with functions such as spectrogram displays, interference analysis, and measurements for selected cellular technologies.

The FSH20 is available in different hardware configurations. One version includes a tracking generator operating from 300 kHz to 8 GHz and an internal VSWR bridge, supporting additional component, cable, and antenna testing with the appropriate options. These capabilities depend on the specific unit’s hardware and installed licenses.

Designed for on-site use, the FSH20 combines battery operation with a rugged, splash-resistant housing. Users can save measurement results for documentation, while R&S InstrumentView software helps prepare measurement settings and procedures before visiting a site. These features make it practical for installing, maintaining, and troubleshooting RF systems.
