- Rohde & Schwarz introduces the R&S FNH series of handheld analyzers, which combine spectrum analysis, real-time spectrum analysis (RTSA), vector network analysis (VNA), and power measurement capabilities.
- Designed primarily for on-site installation, maintenance, and monitoring operations, this instrument covers a frequency range of up to 32 GHz for spectrum analysis and up to 26.5 GHz for vector network analysis.
The analyzer comes with built-in spectrum analysis capabilities as standard. Additional functions—including real-time analysis, cable and antenna testing (CAT), and two-port vector network analysis—can be activated via option codes. Power measurement is also supported by connecting a Rohde & Schwarz USB power sensor. An additional option is available for the analysis of pulsed signals.
In real-time mode, the R&S FNH series analyzer offers a bandwidth of up to 125 MHz and a specified minimum intercept time of 3.6 µs. It also enables the capture of IQ data across this bandwidth, facilitating signal analysis and the detection of radio-frequency interference. A channel scanner automates measurements across predefined frequency lists. Furthermore, the instrument includes an integrated power meter that provides both peak and average power readings.
An instrument designed for field operations
This analyzer is specifically engineered for applications within the aerospace, space, and defense sectors. It is designed for the testing and maintenance of radar systems, satellite ground stations, and communication equipment, as well as for interference hunting and radio spectrum monitoring.
The unit features an IP51-rated enclosure and operates within a temperature range of –10 °C to +55 °C. An optional rain-protection cover is available, which increases the ingress protection rating to IP54. The device can also be used in laboratory environments for R&D or training purposes. It is compatible with R&S VSE software, which facilitates tasks such as signal analysis and demodulation.
Three versions available
The R&S FNH series analyzer is offered in three versions, initially covering frequency ranges up to 6 GHz, 13 GHz, and 26.5 GHz. These limits can be extended to 8 GHz, 20 GHz, and 32 GHz (for the highest-range model)—with the latter extension specifically applying to spectrum analysis.
This new device replaces the R&S FSH and R&S ZVH portable analyzers in the manufacturer’s product portfolio. It is being unveiled for the first time at the electronica 2026 trade fair in Munich, held from November 10 to 13. Rohde & Schwarz offers a standard three-year warranty.
