Rohde & Schwarz is about to revolutionize the sector of sign and spectrum evaluation with the launch of the FSWX sign and spectrum analyzer, an revolutionary instrument designed to beat the restrictions of present measurement strategies.
Rohde & Schwarz launched the brand-new FSWX sign and spectrum analyzer, the primary multichannel sign and spectrum analyzer with a number of enter ports, unlocking new potentialities in sign evaluation. It’s also the primary instrument of its form with a cutting-edge inside multi-path structure enabling a novel cross-correlation function. Mixed with its low part noise for top sign purity, its spurious-free dynamic vary and its excellent residual EVM, the FSWX delivers an RF efficiency like no different sign and spectrum analyzer available in the market.
The instrument’s huge inside bandwidth of 8 GHz permits for complete evaluation even of advanced waveforms and modulation schemes. Mixed with a excessive measurement velocity and evaluation instruments tailor-made to the person’s wants, the FSWX brings new ranges of efficiency and precision to sign evaluation for contemporary RF functions – from energetic RF elements testing to state-of-the-art automotive radar testing to advanced airborne radar situations and satellite tv for pc check in A&D functions to the newest check challenges in WLAN and mobile applied sciences like 5G and past.
Michael Fischlein, Vice President Spectrum & Community Analyzers, EMC & Antenna Take a look at at Rohde & Schwarz, is thrilled to introduce the brand new FSWX: “Our staff has actually re-imagined sign and spectrum evaluation expertise with our new FSWX. They’ve provide you with an revolutionary structure and design to empower our prospects to deal with advanced measurement situations within the evolving panorama of wi-fi communications and radar expertise that had been beforehand unattainable. In different phrases, the FSWX makes measuring the not possible, attainable.” The instrument’s revolutionary design options embody a number of enter ports, cross-correlation capabilities, superior filter banks and broadband ADCs.
A number of enter ports
The multichannel FSWX provides the power to measure a number of sign sources concurrently, no matter whether or not they function on the identical or totally different frequencies. With synchronous enter ports, every that includes 4 GHz evaluation bandwidth, customers can seamlessly analyze the interactions between numerous indicators. This opens up a large number of recent measurement situations, as an illustration, phase-coherent measurements of antenna arrays utilized in beamforming for wi-fi communications in addition to in airborne and automotive radar sensors.
Multi-path structure and cross-correlation
Its superior inside multi-path structure permits for the cross-correlation mode, a novel function of the FSWX. A single sign enter is internally break up into two unbiased sign paths, every outfitted with its personal native oscillator and ADC. With this revolutionary design, superior cross-correlation algorithms might be utilized within the digital backend, successfully eradicating the inherent noise of the measurement instrument. This function reveals spurs not simply seen with out cross-correlation. It’s particularly useful when, as an illustration, measuring Error Vector Magnitude (EVM), a crucial think about cellular communications. The added wideband noise of conventional sign and spectrum analyzers limits the accuracy and dynamic of EVM measurements. With the cross-correlation function, nonetheless, the FSWX gives an unobstructed view of the DUT for exact EVM evaluation.
The inner multi-path structure additionally provides superior triggering choices. For instance, customers can apply an IF or RF energy set off at distinct frequencies, because the multi-path design permits for unbiased frequency settings for every obtain path behind the splitter. This fashion, the FSWX can simply reveal results between two RF indicators.
Superior filter banks and broadband ADCs
Historically, for preselection within the microwave vary, spectrum analyzers depend on YIG filters. Since they’re identified for his or her difficult frequency response, YIG filters should be bypassed for wideband sign evaluation. The FSWX, nonetheless, employs broadband ADCs together with filter banks that span your complete working frequency vary, permitting for pre-selected sign evaluation whereas eliminating the necessity for YIG filters. The filter banks present excessive precision, optimizing instrument settings for particular functions and considerably lowering the danger of undesirable sign photographs contaminating outcomes. For customers requiring narrowband functions, a YIG filter can nonetheless be added optionally.
Revolutionary firmware functions
The FSWX additionally gives revolutionary firmware functions such because the CrossACT (Cross Utility Management and Triggering) firmware function. It synchronizes varied measurements throughout totally different enter channels, permitting for simultaneous evaluation with a number of instruments. This functionality simplifies comparisons, akin to figuring out whether or not the upper harmonics of a radar sign straight influence the EVM efficiency of a 5G sign.
The Linux-based working system of the FSWX gives a excessive degree of safety and long-term help, important options for customers in security-sensitive environments. This strong working system ensures reliability and stability, making the FSWX a super alternative for demanding functions.
