  • 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.

  • 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.

  • 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.

  • How to Run WCDMA BER/ BLER Tests Using R&S Vector Signal Generators

    This application note shows how to run 3GPP WCDMA BER and BLER tests according to standard TS 25.141 with the Vector Signal Generators R&S®SMBV100A, R&S®SMJ100A, or R&S®SMU200A. The description of hardware test setup is followed by detailed instructions on how to configure the R&S® generators and how to run a BER or BLER test step by step. Remote control commands for the generators are included, to simplify integrating the BER/BLER tests into your proprietary test suite.

  • 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.

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    This application note has been replaced by application note 1MA74 RSCommander.

  • Measurement of Maximum Sound Pressure Level of Headphones according to EN50332

    This application note explains how to use the Audio Analyzer R&S UPV for measurements of maximum sound pressure level of headphones according to EN50332. It is possible to measure a combination of music player / FM receiver and headphones, the maximum output voltage of a player / FM receiver alone or the wideband characteristic voltage of headphones alone. An application program is available for download as installer file and as VB.NET project.

  • Measurements on 3GPP WCDMA User Equipment According to Standard TS 34.121

    Application Note 1MA68 has been replaced by 1MA130.

  • 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.
