Handheld Spectrum Analyzer FSH

Versatile, high-performing Rohde & Schwarz handheld spectrum analyzers meet all requirements for field use

Munich, November 17, 2008 — Rohde & Schwarz is presenting two truly all-purpose instruments for mobile spectrum analysis: the R&S FSH4 and the R&S FSH8. Both analyzers are rugged, handy and lightweight. They also come equipped with a powerful battery pack. The R&S FSH4 and R&S FSH8 cover the frequency range from 9 kHz to 3.6 GHz or 8 GHz. Depending on the options installed, they can also be used as two-port vector network analyzers, as cable and antenna testers or as power meters. This means that they support almost all RF measure¬ment tasks encountered in service, installation and maintenance applications.

Mobility, ease of operation, superior measurement characteristics and versatility are the assets that make it possible for the new R&S FSH analyzers to simplify and facilitate daily work. Their low weight of only 3 kg (including battery) and their compact size make them ideal for mobile use. The battery can power up to 4.5 hours of operation. If the field work takes longer, on-site replacement of the battery poses no problem. Since the R&S FSH analyzers conform to protection class IP51 and feature splash-proof, dust-protected connectors, they are reliable tools even under adverse ambient conditions.

In addition to their low weight and compact size, their vertical design makes the analyzers extremely handy. The user can easily reach all keys without having to put down the instrument. Flat menu structures and separate keys for frequently used functions help ensure efficient work. The large, high-contrast VGA color display is easy to read even under difficult lighting conditions.

Thanks to their outstanding RF characteristics, the R&S FSH4 and the R&S FSH8 are top in their class: A displayed average noise level of e.g. –163 dBm (1 Hz) at 2 GHz and a preamplifier that can be activated on all models can measure even very small signals reliably. In the presence of multiple strong signals, the analyzers' excellent large-signal immunity helps prevent internal interference. Featuring third-order intercept of 15 dBm in the common mobile radio bands, the analyzers perform comparably to high-end desktop models. The level measurement uncertainty is low and amounts to max. 1 dB for measurements up to 3.6 GHz and max. 1.5 dB up to 8 GHz.

Besides the base models, Rohde & Schwarz offers models with built-in tracking generator as well as models with an integrated VSWR bridge for vector network analysis. Sensors that are also available from Rohde & Schwarz convert the R&S FSH4 and the R&S FSH8 into high-precision power meters. This means that the analyzers provide all the functions for the installation and maintenance of radio transmitter systems in a single box: assessment of transmission spectrum, detection of interference, measurement of transmit power, checking of antenna matching, verification of the amplifiers on the antenna, and measurement of the antenna cable quality.

Windows software is supplied with the analyzers for recording and evaluating measurement results. The software also supports maintenance teams with large equipment pools in administering instrument setups. This feature eliminates the need to configure each instrument separately. The analyzer connects to a PC via LAN or USB interface. Since practically all functions can be remote-controlled, the handheld analyzers can be integrated into customer-specific programs.

The various R&S FSH4 and R&S FSH8 models for mobile use are now available from Rohde & Schwarz.
