Rohde & Schwarz launches new FNH handheld spectrum and network analyser
Rohde & Schwarz has introduced the R&S FNH, a new handheld combination analyser that brings spectrum analysis, real-time spectrum analysis (RTSA), vector network analysis (VNA) and power metering together in a single rugged, portable instrument. Designed for demanding field environments as well as laboratory applications, the R&S FNH delivers laboratory-grade measurement performance at frequencies up to 32 GHz for spectrum analysis and 26.5 GHz for vector network analysis.
With real-time spectrum analysis and IQ capture bandwidths of up to 125 MHz, the R&S FNH is designed to support on-site troubleshooting, signal monitoring and in-depth analysis. Its compact form factor can be further customised through a comprehensive range of optional features and software upgrades, allowing users to configure the instrument for specific measurement requirements.
Flexible measurement capabilities in one handheld instrument
Rohde & Schwarz is showcasing the new R&S FNH at the electronica trade fair in Munich. Spectrum analysis is included as standard, while additional measurement capabilities can be activated using keycodes. These include real-time spectrum analysis (RTSA), cable and antenna testing (CAT) and two-port vector network analysis (VNA).
The instrument also supports power measurements using a compatible Rohde & Schwarz USB power sensor, with optional pulse analysis extending its measurement capabilities further.
Offering a real-time analysis bandwidth of up to 125 MHz, the R&S FNH provides a leading level of performance for a handheld combination analyser. This wide bandwidth enables an intercept time as short as 3.6 μs, helping engineers detect and analyse short-duration signals. The instrument also features a low displayed average noise level (DANL) and low voltage standing wave ratio (VSWR) across its supported frequency ranges.
Rugged design for aerospace and defence applications
Developed with demanding aerospace and defence applications in mind, the R&S FNH is built to withstand challenging operating conditions. It meets IP51 protection requirements and operates across a temperature range of -10 °C to +55 °C. An optional rain holster increases the protection rating to IP54, providing additional protection when working in exposed environments.
These capabilities make the handheld analyser suitable for the installation, maintenance and calibration of radar systems, satellite ground stations and communications infrastructure. It can also support interference hunting and spectrum monitoring, helping engineers identify and investigate unwanted signals in the field.
From field testing to laboratory research and development
Beyond field applications, the R&S FNH’s compact design makes it suitable for laboratory research and development (R&D), as well as education and training environments.
The instrument is compatible with Rohde & Schwarz R&S VSE software for signal demodulation analysis. Its channel scanner automates measurements across predefined channel lists, while the integrated power meter provides both peak and average power readings.
Three hardware versions with expandable frequency coverage
The R&S FNH replaces the R&S FSH and R&S ZVH handheld analyser families. It is available in three hardware versions, with standard frequency coverage up to 6 GHz, 13 GHz and 26.5 GHz.
The frequency ranges can be extended through optional upgrades to 8 GHz and 20 GHz for the respective lower-frequency models. The 26.5 GHz version can be upgraded to support spectrum analysis up to 32 GHz, providing additional flexibility for demanding high-frequency measurement applications.
