Rohde & Schwarz Launches R&S FNH Handheld Analyzer With Spectrum and Network Analysis Capabilities

The new R&S FNH handheld analyser from Rohde & Schwarz combines spectrum analysis, real-time spectrum analysis (RTSA), vector network analysis (VNA) and power measurements in a single compact and rugged device. Users can add different features and options to configure the instrument for specific testing requirements. It supports spectrum analysis at frequencies up to 32 GHz and vector network analysis up to 26.5 GHz, delivering laboratory-level performance in field conditions. It also offers real-time analysis and IQ data capture with a bandwidth of up to 125 MHz, making it suitable for both on-site RF troubleshooting and laboratory testing.

Rohde & Schwarz is showcasing its new R&S FNH handheld analyser at electronica 2026 in Munich. Spectrum analysis comes as a standard feature, while additional functions such as real-time spectrum analysis (RTSA), cable and antenna testing (CAT) and two-port vector network analysis (VNA) can be activated using software keycodes. The instrument can also connect to a Rohde & Schwarz USB power sensor for power measurements, with pulse analysis available as an optional feature.

Its real-time bandwidth of up to 125 MHz is industry-leading for a handheld combi analyser. This allows for a shorter intercept time of 3.6 µs. In addition, the R&S FNH provides a low displayed average noise level and a low voltage standing wave ratio (VSWR) across its frequency ranges.

Built for aerospace and defence applications

The R&S FNH is designed for aerospace and defence applications. It meets IP51 protection requirements and operates between -10 °C and +55 °C. An optional rain holster increases the protection to IP54, so it is suitable for confined or harsh environments. These features make it ideal for installation, maintenance and calibration of radar systems, satellite ground stations and communication systems in the field, as well as for interference hunting and spectrum monitoring.

Beyond field use, its compact design supports laboratory R&D and education applications. The device works with the R&S VSE software for signal demodulation analysis. A channel scanner automates measurements across predefined lists, while an integrated power meter provides peak and average power readings.

The new R&S FNH handheld combi analyser replaces the R&S FSH and R&S ZVH models. It is available in three hardware versions, covering frequency ranges up to 6 GHz, 13 GHz and 26.5 GHz, which can be expanded up to 8 GHz, 20 GHz and the 26.5 GHz model up to 32 GHz for spectrum analysis.

Michael Fischlein, Vice President RF Test Solutions at Rohde & Schwarz, states: “With the R&S FNH handheld combi analyser, Rohde & Schwarz presents a worthy successor to the legendary R&S FSH and R&S ZVH handheld analysers. The device combines the widest real-time bandwidth in its class with a comprehensive feature set for spectrum analysis and two-port VNA measurements. Outstanding RF performance and versatile measurement functions make the R&S FNH a complete measurement lab in pocket format.”
