  • Multi-Channel Signal Generation Applications with R&S®SMW200A – Overview

    The R&S®SMW200A vector signal generator has the outstanding ability to simultaneously generate up to eight independent signals from a single instrument. The advanced multi-channel architecture allows realizing even complex applications like MSR, carrier aggregation, MIMO or enhanced interference scenarios with a minimum of effort.This application note gives an overview of common multi-channel application examples and how to equip the Rohde & Schwarz signal generator R&S®SMW200A appropriately.

  • Measuring Multistandard Radio Base Stations

    3GPP Release 9 Technical Specification (TS) 37.141 covers multistandard radio base station conformance testing. Multistandard radio includes four standards of mobile communications: GSM, WCDMA, TD-SCDMA, and LTE. This application note introduces the concept of multistandard radio base stations as well as solutions for transmitter and receiver tests based on Rohde & Schwarz signal generators and Rohde & Schwarz signal and spectrum analyzers.

  • Voice over LTE (VoLTE) Speech Quality Measurements

    This application note and associated application software may be used to conduct psychoacoustic speech quality evaluation for Voice over LTE (VoLTE) connections. The measurements are based on recommendations ITU-T P.862 and ITU-T P.863, respectively.

  • Testing LTE Release 9 Features

    LTE – the fastest growing mobile radio standard – had its beginnings in 3GPP Release 8. Initial improvements and new features were implemented in Release 9. This Application Note describes the T&M methods for LTE Release 9 features using Rohde & Schwarz instruments.

  • 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.

  • 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.

  • LTE- Advanced (3GPP Rel.11) Technology Introduction

    The LTE technology as specified within 3GPP Release 8 was first commercially deployed by end 2009. Since then the number of commercial networks is strongly increasing around the globe. LTE has become the fastest developing mobile system technology. As other cellular technologies LTE is continuously worked on in terms of improvements. 3GPP groups added technology components into so called releases. Initial enhancements were included in 3GPP Release 9, followed by more significant improvements in 3GPP Release 10, also known as LTE-Advanced. Beyond Release 10 a number of different market terms have been used. However 3GPP reaffirmed that the naming for the technology family and its evolution continues to be covered by the term LTE-Advanced. I.e. LTE-Advanced remains the correct description for specifications defined from Release 10 onwards, including 3GPP Release 12. This white paper summarizes improvements specified in 3GPP Release 11.

  • Guidelines for MIMO Test Setups – Part 1

    Multiple antenna systems, known as MIMO systems, form an essential part of today’s wireless communications standards. This multi-antenna technology efficiently boosts the data throughput without requiring additional bandwidth, and has thus become a key technology. Rohde & Schwarz offers high-performance MIMO test solutions which provide static conditions without fading as well as simulation of complex fading scenarios.This application note explains how to set up 4x4 and 8x8 MIMO systems using the R&S®SMBV100A signal generator for measurements under static conditions without fading.For simulation of complex fading scenarios please refer to application note 1GP97.

  • 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.
