The R&S®FSW-K6S time sidelobe measurement option measures pulse compression parameters

The R&S®FSW-K60/K60H option analyzes frequency hopping signals

Automotive radar signal analysis

Image-free wideband signal analysis in the E band  

The R&S®FSW85 signal and spectrum analyzer features a YIG preselector for frequencies between 8 GHz and 85 GHz, providing image-free spectrum analysis. The wide analysis bandwidth (up to 8.3 GHz) combined with the R&S®FSW-K60/-K60C transient analysis/chirp measurement option allows you to characterize up to 5 GHz wide FMCW signals such as those used in automotive radars.

Ideal for satellite RF testing

High-performance measurement solutions for designing, developing and testing satellite payloads, payload subsystems and components  

The FSW offers dedicated measurement applications for the most critical measurements such as group delay, linearity, gain transfer, noise power ratio (NPR), etc. It also demodulates satellite RF signals of several standards such as DVB-S2X and OneWeb. The FSW scalable, wide analysis bandwidth (up to 8.3 GHz) meets the increasing demand for wide signal bandwidths.

Real-time spectrum analysis

Don’t miss a thing with the real-time spectrum analysis option

The FSW real-time options allow users to reliably detect extremely short sporadic interference in the nanosecond range even in close proximity to powerful carriers – in a bandwidth of up to 800 MHz. Real-time spectrum analysis enables users to analyze existing frequency hopping algorithms and create alternative ones to prevent collisions between signals of different standards operating in the same frequency band.

Powerful vector signal analysis application

Digital signal analysis  

The R&S®FSW-K70 vector signal analysis option enables users to flexibly analyze digitally modulated single carriers down to the bit level. The clearly structured operating concept simplifies measurements despite a wide range of analysis tools.The R&S®FSW-K70M allows analysis of signals with two different modulation schemes, such as DVB-S2X signals.The R&S®FSW-K70P extension measures the raw bit error rate (BER) on PRBS data up to PRBS23.
