The R&S®FSW signal and spectrum analyzer is a high-performance instrument capable of measuring many key system and component parameters. Using the bit error rate (BER) functionality of the R&S®FSW-K70P option, the raw data error performance of a component or system can be accurately determined.

Energy efficiency of RF Frontends (RFFE), especially transmitters, continues to gain greater prominence.Meeting the efficiency challenge is increasingly difficult at higher operating frequencies and bandwidths, such as those proposed for 5G.There is a group of transmitter RFFE architectures whose signal output is constructed from two, or more, efficiently generated components. This signal construction in effect, means that such architectures use predictive, post-correction linearization. Their predictive nature enables distortion to be completely eliminated.The capabilities of multi-channel signal synthesis setups with R&S®SMW200A, in combination with the R&S®FSW analyzer enable measurement, hence development, of these types of transmitters.The document focusses on devices for the 3.5 GHz NR (5G New Radio) candidate band, but its findings are equally applicable to developments and measurements for, for example, K-band satellite applications or mmW NR candidate bands, where efficiency is an even more crucial design target.

This Application Note gives a short overview how signals with two different modulation schemes can be analyzed using the R&S®FSW (or R&S®FPS) using its Multi-Standard-Radio-Analyzer (MSRA) and Vector Signal Analysis personality. The Application Note focuses on DVB-S2(X) signals, but the approach may be used for similar signals as well, as e.g. used in microwave backhaul links.The Application Note also provides a software tool that automates the configuration and provides the variety of different constellations that are used within DVB-S2(X).

The need for higher data rates and flexibility for IP and Cable TV (CATV) has led to the introduction of DOCSIS®3.1. With channel bandwidths up to 192 MHz and 96 MHz on the downstream and upstream respectively as well as the cable network frequency extension up to 1.2 GHz (1.8 GHz as a future extension) the technical requirements of cable components have increased significantly. This application note describes a test scenario tor testing cable components with an R&S®CLGD Cable Load Generator for DOCSIS 3.1 or R&S®SFD DOCSIS 3.1 Generator and an R&S®FSW Signal & Spectrum Analyzer.
