The new high-end R&S FSW signal and spectrum analyzer from Rohde & Schwarz provides outstanding RF performance and bandwidth and offers developers the ability to view multiple measurement applications at a glance as well as analyze signal interactions. The R&S FSW comes in three models that cover the frequency ranges 2 Hz to 8 GHz, 13 GHz or 26.5 GHz and has been specifically designed to meet the requirements of development laboratories in the aerospace, defense and communications industries.

The practical 12.1" touchscreen offers a MultiView function that enables users to display the results of different applications at the same time, enabling them to keep track of even the most complex signal analyses and find errors more easily. An additional benefit is the elimination of time-consuming switching between measurement applications.

At 10 kHz carrier offset, the R&S FSW achieves a phase noise specification of less than –137 dBc (1 Hz), which is especially important for developers of RF components and complete systems for radar applications. By taking advantage of the analyzer's phase noise specification, more stable radar signals can be achieved. Equipped with the R&S FSW-K6 option, the R&S FSW also supports comprehensive analysis of pulsed signals, e.g. for radar applications. Its broad analysis bandwidth of up to 160 MHz enables it to measure wideband, hopping and chirp signals, which makes it ready today for the requirements of tomorrow's wireless standards such as 802.11ac. The signal and spectrum analyzer can also detect spurious emissions quickly thanks to its low inherent noise and its ability to rapidly analyze wide frequency ranges, even when using narrow resolution bandwidths.

Significant for developers of wireless communications base stations and components is the analyzer's broad 160 MHz demodulation bandwidth and multi-standard radio analysis function: The combination of these two features in a single instrument makes it possible to simultaneously measure multiple mobile radio and wireless standards at different frequencies. Users can easily spot signal interaction among the standards.

Commenting at the product’s launch in Memmingen, Germany, Josef Wolf, Director of the Spectrum Analysis, Network Analysis and EMC Subdivision at Rohde & Schwarz, pointed out: "These measurements are essential for multi-standard base stations of the future. That is why we have integrated the multi-standard radio analyzer into the R&S FSW. This feature, combined with the large touchscreen display, provides functionality that is unique on the market. The optimum analyzer for tomorrow's developments is now available today."
