  • 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.

  • LTE rollout challenges: Straight talk from Rohde & Schwarz at LTE World Summit 2011

    Insights into the test challenges involved in rolling out LTE, are presented by Meik Kottkamp, Technology Manager for Rohde & Schwarz, at the LTE World Summit 2011 in Amsterdam.

  • Calibration Tool for PESQ Speech Quality Tests

    PESQ measurements employ a level adaptation algorithm and are hence widely insensitive to absolute level. However, if the tests are performed via a speech codec, the driving level of the codec has an influence on the MOS result. Therefore careful alignment of the level is required. This application note provides an application program which runs on the Audio Analyzer R&S UPV or R&S UPV66 and can be used to calibrate signal levels for the PESQ measurement.

  • LTE Terminal Tests under Fading Conditions with R&S®CMW500 and R&S®AMU200A

    This application note shows how to perform LTE terminal block error rate (BLER) and throughput tests under fading conditions with the R&S®CMW500 Protocol Tester and the R&S®AMU200A Fading Simulator.

  • LTE-A Base Station Performance Tests

    3GPP TS36.141 defines conformance tests for EUTRA base stations (eNodeB). Release 12 (LTEAdvanced) added several tests, such as those for PUCCH format 2 and PUSCH with TTI bundling and enhanced HARQ pattern.This application note describes how all required performance tests (TS36.141 Chapter 8) can be performed quickly and easily by using vector signal generators from Rohde & Schwarz.Examples illustrate the manual operation. A free software program enables and demonstrates remote operation.The LTE base station transmitter (Tx) tests (TS36.141 Chapter 6) are described in Application Note 1MA154.The LTE base station receiver (Rx) tests (TS36.141 Chapter 7) are described in Application Note 1MA195.

  • Measurement of phase-, timing- and gain offset between 2 signals using multiple spectrum analyzers

    This application note describes how to measure the coherence (phase-, timing and gain-differences) between two RFSignals using Rohde&Schwarz spectrum analyzers, a Rohde&Schwarz signal generator and the R&S FS-Z10 Coherence Unit.

  • RF chipset verification for UMTS LTE (FDD) with R&S®SMU200A and R&S®FSQ

    This application note describes how to verify and validate a LTE (FDD) RF chipset using R&S® SMU200A vector signal generator, R&S® FSQ signal analyzer and R&S® EX-IQ Box. The related signal generation as well as signal analysis is described

  • Testing LTE-A Releases 11 and 12

    LTE is under continuous development. Release 10 (LTE-Advanced) introduced carrier aggregation (CA) as the primary enhancement. Releases 11 and 12 add several new components to LTE. Some are enhancements to existing features (such as improvements to CA), while others are completely new concepts, such as coordinated multipoint (CoMP).This application note summarizes the Rohde & Schwarz test solutions for LTE-Advanced according to Releases 11 and 12 using vector signal generators, signal and spectrum analyzers and the wideband radio communication tester.

  • Measurement of Beamforming Antenna in Transmit Mode

    Rapid and accurate verification of beamforming weights is required for example, for codebook generation or beamforming algorithm development or verification. This document describes the unique application of Rohde & Schwarz VNA (Vector Network Analyzers) to fully characterize the passive part of multi-element antennas intended for beamforming.A range of R&S VNA models are optionally equipped with multiple independent sources, whose relative amplitude and phase may be arbitrarily controlled ("defined coherence mode"), in addition to frequency and true time delay. These sources may be connected to individual elements of a multi-element antenna to derive and verify transmit (Tx) mode beamsteering and beamforming operation.The R&S®ZVA in "Defined Coherence Mode" can electronically be switched to / from the conventional S-parameter mode. Therefore, Sparameter and beamforming measurements may be performed efficiently within a single connection cycle of the antenna.Multiple VNA may be daisy-chained, to extend the concept shown to support an arbitrary number of ports.The R&S®Quickstep sequencing software may be downloaded from:https://www.rohde-schwarz.com/software/quickstep/

  • Acoustic Test Software for Mobile Phones in Service and Repair

    This application note provides software and instructions for a simple check of the acoustic performance of mobile phones. It targets mainly service centers and repair workshops which have to perform incoming tests of defective mobile phones and final tests of repaired mobiles. A focus is set on short test times and ease of use, without compromising accuracy and repeatability of results.
