Be ahead in 5G development

In-depth 5G physical layer signal analysis

The R&S®FSW scalable, wide internal analysis bandwidth of up to 8.3 GHz allows you to capture the entire bandwidth of the downlink signal and evaluate the complete system.
The R&S®FSW-K144 and R&S®FSW-K145 options cover in-band measurements of 3GPP 5G NR in the downlink and uplink. Each signal subframe is analyzed and a wide range of measurement results are provided, including the EVM, frequency and power of different channels and signals.

**R&S®FSW-K144 5G New Radio downlink application** - R&S®FSW-K144 detects and sets many parameters automatically, giving you more time to concentrate on the insights gained from the detailed analysis.

Extensive radar analysis functions

Fast and comprehensive radar signal analysis

In addition to its wide analysis bandwidth (up to 8.3 GHz), the analysis functions offered by the R&S®FSW are essential for radar testing.

The R&S®FSW-K6 pulse measurement application measures all relevant pulse parameters at the touch of a key
The R&S®FSW-K6S time sidelobe measurement option measures the pulse compression parameters
The R&S®FSW-K60/K60H option analyzes frequency hopping signals

**R&S®FSW-K6 pulse measurement option.** - The R&S®FSW-K6 pulse measurement application measures all relevant pulse parameters at the touch of a button.

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. Its 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 like those used in automotive radars.

**Automotive radar measurements** - FMCW signal with 2 GHz bandwidth at 77 GHz measured with the R&S®FSW-K60C option and the R&S®FSW-B2001 2 GHz internal bandwidth extension

Ideal for satellite RF testing

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

The R&S®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 R&S®FSW scalable, wide analysis bandwidth (up to 8.3 GHz) meets the increasing demand for wide signal bandwidths.

**R&S®FSW-K17 multicarrier group delay measurements.** - Measures absolute and relative group delay with high accuracy within milliseconds.

Real-time spectrum analysis

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

The R&S®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.

**Real-time spectrum of the ISM band at 2.4 GHz.** - Analyzes and prevents collisions between signals of different standards operating in the same frequency band (e.g. WLAN and Bluetooth®).

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.

**Analysis of a 1024QAM modulated signal.** - Constellation diagram, result table, symbol table and EVM distribution.
