Rohde & Schwarz offers different analog and digital signal generators: from RF vector signal generators, baseband signal generators, microwave signal generators.

Overview Key FactsThe R&S®AFQ-K241 option extends the R&S®AFQ-K240 GSM/EDGE option to EDGE evolution. Key FactsEDGE evolution (sometimes also called EDGE+ or EGPRS2) is an enhancement of the GSM/EDGE standard to increase the maximum data throughput of the existing GSM/EDGE network by means of minor modifications.

GPRS (General Packet Radio Service) and EDGE (Enhanced Data Rates for GSM Evolution) provide data capabilities in widely deployed 2G networks reaching peak and average data rates of 384kpbs and 200kbps, respectively. Within 3GPP Release 7, further improvements to GPRS/EDGE have been specified in the context of EDGE evolution. This application note introduces key features of EDGE evolution and outlines the changes to the radio interface.

Polar modulation is a method where digital modulation is realized as a combination of phase and amplitude modulation, rather than using an I/Q modulator. This technique becomes increasingly important in mobile communication. This application note shows how to generate polar modulation with an R&S®SMU200A Vector Signal Generator.

Short measurement time in conjunction with high accuracy and repeatability of results are essential for efficient testing of mobile phone power amplifiers. Power Meter R&S®NRP, Signal Generator R&S®SMIQ, Spectrum Analyzers R&S®FSP/FSU/FSQ and Power Supply R&S®NGMO2 offer optimum characteristics such as high accuracy, fast settling speed and short measurement time in programmed mode. This application note concentrates on testing GSM/EDGE mobile power amplifiers and shows typical test setups and programming examples for Signal Generator R&S®SMIQ and Spectrum Analyzer R&S®FSP/FSU/FSQ, benchmark numbers and repeatability results.
