  • Test Automation Tool for POLQA® and PESQ® Speech Quality Tests

    This application note provides an application program for level alignment, test automation and reporting with PESQ, POLQA and delay measurements on the Audio Analyzer R&S®UPV or R&S®UPV66.

  • 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.

  • eCall Conformance and Performance Testing

    Emergency Call (eCall) is a service provided in Europe with the goal of reducing response times for accidents or other emergencies on the roadways. This application note briefly describes the technology behind eCall and presents conformance tests for eCall using the R&S®CMW500 RF tester and the R&S®SMBV100A vector signal generator. A Test software for eCall makes it quick and easy to perform these tests with the GSM or WCDMA wireless communications standard. It also shows a test solution for GNSS performance tests for eCall using the R&S®SMBV100A vector signal generator and the option R&S®SMBV-K361 together with CMWrun.

  • 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.

  • 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.

  • Generating the Noise Field for Ambient Noise Rejection Tests

    This application note describes how to generate the noise field for ambient noise rejection tests according to 3GPP TS 26.132, sections 7.9 and 8.9.

  • Measurements on GSM Base Stations According to Rec. 11.20

    The following application note describes the function and operation of user menus for FSE Spectrum Analyzers including option Vector Signal Analysis (FSE-B7). For measurements according to the GSM standard user menus are provided, which perform settings on FSE for Base Station testing required in the standard. The menu and the accompanying setups are stored on a floppy disk. For operation of the menus firmware version 1.40 or higher is required. Option Vector Signal Analysis FSE-B7 has to be installed for the use of the application menu.

  • Importing Data in ARB, Custom Digital Modulation and RF List Mode

    The foregoing application note is intended for everyone who desires to become more familiar with the use and upload of custom data in ARB, digital modulation and RF list mode. Particularly, this note describes the instruments R&S® SMW200A, R&S® SGT100A, R&S® SMBV100A, R&S® SMU200A, R&S® SMJ100A and R&S® SMATE200A and provides an overview of already available solutions as well as it gives hints for the writing of own applications. Please also see the application note 1GP88 for the ARB Toolbox software and the application note 1GP96 for the CDM-Toolbox software.

  • Calibrating the CMD Output Level for BER

    The CMD 57/59 output level for BER measurement can be calibrated to high accuracy to match GSM 11.21, (with modulated signals and adjacent timeslots + 50 dB above the used timeslot) using a simple test setup containing an NRVD power meter and an FSE spectrum analyzer.
