  • Increase the IP connection security of your IoT device

    The new IP connection security analysis solution for the R&S®CMW500 platform identifies IoT and mobile communications devices’ IP connection vulnerabilities in an early stage of development.

  • RSCommander

    Versatile Software Tool for Rohde & Schwarz InstrumentsRSCommander is a versatile software tool for a wide range of Rohde & Schwarz spectrum-, network analyzers, signal generators and oscilloscopes. It allows for automatic instrument discovery, making screenshots, reading traces, file transfer and simple script creation.

  • Replacing R&S® CMU200 with R&S® CMW500 in 2G and 3G Speech Test Applications

    The combination of R&S® CMU200 and R&S® UPV is in use for various tests of mobile phone speech functionality, such as acoustic tests according to 3GPP 26.132 or speech quality tests according to ITU-T P.862 (PESQ®) or ITU-T P.863 (POLQA®). This application note explains how to replace the R&S® CMU200 in these tasks with R&S® CMW500.

  • Spectral and Time-Domain Analysis of Recorded Wave Files on the Audio Analyzer R&S® UPV

    The instrument setup provided in this application note allows to analyze a degraded speech signal stored into a wave file and to display its FFT spectrum and waveform.

  • Next-Generation (3G/4G) Voice Quality Testing with POLQA®

    This white paper describes the POLQA® algorithm implemented in the R&S®UPV Audio Analyzer and shows an example hardware setup for standard independent audio measurements.

  • High Speed Uplink Packet Access (HSUPA) White Paper

    High Speed Uplink Packet Access (HSUPA) is a 3GPP release 6 feature for WCDMA. Objective is to achieve uplink data rates of up to 5.76 Mbps and increase throughput and capacity. This application note introduces HSUPA concepts and explains key features.

  • HSPA+ Technology Introduction - White Paper

    High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) optimize UMTS for packet data services in downlink and uplink, respectively. Together, they are referred to as High Speed Packet Access (HSPA). Within 3GPP Release 7, 8, 9 and 10, further improvements to HSPA have been specified in the context of HSPA+ or HSPA evolution. This White Paper introduces key features of HSPA+ and outlines the changes to the radio interface.

  • CMUCopy - Transferring CMU Hardcopy to PC using the IEEE Bus or the serial interface

    This application note has been replaced by application note 1MA74 RSCommander.

  • Generating and Analyzing 3 GPP Multicarrier Signals with High Dynamic Range

    This application note describes three ways of generating multicarrier signals with high dynamic range for testing power amplifiers of 3GPP radio base stations. The corresponding sets of waveform (*.wv) files are delivered with this application note. The WinIQSIM™ software is used to download these files to the signal generator(s).Tips for optimizing spectrum analyzer settings in order to measure the Adjacent Channel Leakage Ratio (ACLR) are given.

  • 3GPP FDD and LTE Multicell and Multi-UE Scenarios with the R&S®SMU200A Signal Generator

    This application note describes how to set up 3GPP FDD and LTE multicell and multi-UE scenarios with the R&S®SMU200A with a focus on routing and leveling of the baseband signals. Furthermore, it describes in detail how to determine the correct AWGN settings, i.e. how to calculate the required signal-to-noise ratio for the various scenarios.
