RF performance that meets exacting demands The R&S®FSW redefines the top of the line for signal and spectrum analyzers, offering superior RF performance in terms of phase noise, displayed average noise level (without noise cancellation), intermodulation suppression and d ­ ynamic range for ACLR and harmonic measurements. Unmatched phase noise – ideal for ­ easuring m oscillators for radar and communications applications Developers of oscillators, synthesizers or transmit systems benefit from the R&S®FSW's excellent dynamic range for phase noise measurements. At 10 kHz offset from the carrier,...

Excellent dynamic range for spurious m ­ easurements thanks to low DANL Featuring a low displayed average noise level (DANL) of typ. –159 dBm (1 Hz) at 2 GHz and –150 dBm (1 Hz) at 25 GHz without using a preamplifier, the R&S®FSW measures spurious emissions quickly and reliably over a wide frequency range. DANL can be further improved by up to 13 dB by means of the analyzer's switch-selected noise cancellation. Users can thus identify even the smallest of spurious that were previously hidden in the noise floor, and effectively optimize transmit systems. Harmonic measurements made easy – due to...

Up to 500 MHz analysis bandwidth The demand for analysis bandwidth is continuously increasing. This becomes apparent when power amplifiers for multicarrier or wideband applications have to be linearized in order to make them more effective, or when the occupied bandwidth of communications systems themselves increases. The R&S®FSW is ready to take on this challenge – offering analysis bandwidths of up to 500 MHz. Configuration Maximum Applications analysis bandwidth Standard ❙❙ Standard applications and measurements on single carriers, e.g. WCDMA, CDMA2000®, TD-SCDMA, TETRA carriers ❙❙ Modulation...

High spurious-free dynamic range of > 100 dBc In addition to A/D converter resolution, the available s ­ purious-free dynamic range (SFDR) plays an eminent role when analyzing I/Q data. With an SFDR well over 100 dBc, the R&S®FSW offers unprecedented accuracy when it comes to linearizing amplifiers or measuring EVM. Large I/Q memory depth for seamless recording of long signal sequences The R&S®FSW has a 400 Msample I/Q memory depth. S ­ ignals can be recorded over extended periods of time, even when analyzing large bandwidths. This makes it e ­ asier to identify and analyze sporadic errors. Analysis...

Designed for convenience – with straightforward result display The R&S®FSW turns into a reality what many users desire: configuration, measurement and analysis that are truly intuitive. Efficient operation with optimized user guidance From block diagrams reflecting the signal flow on the R&S®FSW touchscreen, the user can select a desired element and access all functions via straightforward dialogs. The R&S®FSW uses flat menu structures throughout, making it easy to navigate to a desired function or setting. For example, up to eight traces can be configured in a single dialog. Dialog windows are...

Ideal for analyzing radar systems Rapid spurious identification, low phase noise, extensive pulse analysis functions and wide analysis bandwidth make the R&S®FSW signal and spectrum analyzer an essential tool in the development and production of radar systems. Fast identification and analysis of spurious emissions To identify spurious emissions from a transmitter or oscillator, measurements are often carried out over large frequency ranges at narrow analysis bandwidths. Due to its short sweep times, the R&S®FSW delivers results very quickly even for this demanding application. At 1 kHz resolution...

­Identifying ­interaction between signals Multistandard realtime analyzer (MSRT) The multistandard realtime analyzer (MSRT) can be used to detect short, sporadic interference signals and their influence on adjacent signals. The MSRT seamlessly acquires the spectrum. As soon as the frequency mask trigger is activated, the recorded I/Q data is transferred to the measurement application and analyzed. The data covers a settable time span before and after the trigger event. As with the MSRA, time-correlated dependencies between signals are retained. Multistandard radio analyzer (MSRA) The constantly...

Keeping pace with technological advancement Fast innovation cycles, new transmission methods, growing data volumes and ever higher bandwidths mean that analyzers have to constantly cope with new T & M requirements during their useful life. The R&S®FSW has a modular design, i.e. subassemblies such as the controller, the power supply and the digital backend are inserted into slots on the rear. Optional modules, such as for extending I/Q demodulation bandwidth, are likewise accommodated on the rear. Measurement ­ pplications can be activated a with a key code.
