R&S FSH4 and R&S FSH8

Rohde & Schwarz has introduced two instruments for mobile spectrum analysis: the R&S FSH4 and the R&S FSH8. Both analysers 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 9kHz to 3.6 GHz or 8 GHz. Depending on the options installed, they can also be used as two-port vector network analysers, as cable and antenna testers or as power meters. This means that they support almost all RF measurement tasks encountered in service, installation and maintenance applications.

Mobility, ease of operation, superior measurement characteristics and versatility are the capabilities that make it possible for the new R&S FSH analysers 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 analysers 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 analysers 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 colour display is easy to read even under difficult lighting conditions.

The R&S FSH4 and the R&S FSH8 features 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 analysers' large-signal immunity helps prevent internal interference. Featuring third-order intercept of 15 dBm in the common mobile radio bands, the analysers 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.
