  • PESQ® Measurement for CDMA2000® with R&S®CMUgo

    Recent mobile test methods could not evaluate the quality of data reduced speech signals with different coded and decoded signals. The Perceptual Evaluation of Speech Quality (PESQ) provides the solution for this measuring problem. CDMA2000® PESQ is an add-on tool for CMUgo for automatic measurement of the PESQ for CDMA2000® mobile phones according to recommendation ITU-T P.862.1 featuring selectable fading profiles and variable Additional White Gaussian Noise (AWGN).

  • 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.

  • Measurements on PCS1900 Base Stations According to J-STD-007

    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 PCS 1900 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.

  • Converting Existing Waveform Files from R&S®AMIQ or Binary into R&S®SMU200A or R&S®AFQ100A Format

    This application note describes how to use the Rohde & Schwarz software tool ‘RsBatchConvert.exe’ for the conversion of binary data or WinIQSIM generated AMIQ waveforms into the new waveform format. The tool not only rescales I/Q data contained in the file but also changes the K-option requirement from WinIQSIM Kxx to the new WinIQSIM2 K2xx options. Thus, new instruments with installed K2xx options may be used to continue using existing waveform files.

  • CDMA2000®: Packet Data Testing with R&S®CMU200

    The Rohde & Schwarz R&S CMU200 can be configured to perform packet data testing in a Mobile IP or Simple IP environment. This application note is intended as a guide to configuring the necessary Mobile IP or Simple IP network elements and R&S CMU200 instrument.

  • CDMA2000® Base Station Test with R&S Equipment

    This Application Note describes measurements compliant with the cdma2000® base station standard described in 3GPP2 C.S0010 / TIA/EIA-97 / ARIB STD-T64-C.S0010. The primary focus is on solutions for generating and analyzing cdma2000® signals. The special characteristics that make the selected signal generators and signal analyzers eminently suitable for this purpose are detailed, and remote control programming is demonstrated by a free of charge program.

  • 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.
