This application note explains how to bring a CADENCE system which is attached to an R&S EX-IQ-BOX into service for the first time. The first part of the document shows how to setup an LTE Demo without using a UE design. This setup uses the R&S CMW500 as the downlink transmitter. The emulator receives the downlink via an R&S EX-IQBOX and passes it to an R&S spectrum analyzer (R&S FSx) via a second R&S EXIQ-BOX. The second part describes the real wiring using up- and downlink. This will only work if a UE design is available on the emulator.

Verification of baseband data is an important step in the early development phase of LTE/LTE-A-ready products. Comparison values for baseband data (test vectors) from other sources can be very useful in order to verify the correct implementation of the standard. Option K81 for the R&S®SMx200A vector signal generator offers sample data for LTE at the bit level. The reference data enables users to test their own implementation of the specification. The LTE bit stream verification program shown here uses data generated by this option and offers a (bitwise) comparison with bit streams generated for an LTE downlink signal. Therefore it demonstrates, how easy the option R&S SMx-K81 can be integrated into the simulation and design process during the development of LTE/LTE-A handsets or base stations.

Unattended observation of spectrum occupancy for finding spurious emissions or seldom-occuring interferers is a common task for spectrum analyzers. Sometimes spectrum data has to be monitored over quite a long period of time. TraceRecorder, a small, free-of-charge software tool for storing measurement data from Rohde & Schwarz spectrum analyzers helps you to perform this measurement task. Running on a PC, it connects to the spectrum analyzer via a LAN interface. For stand alone operation, it is possible to run it directly on a spectrum analyzer, eliminating the need for an additonal computer during data acquisition.

Modern radio communication systems have to provide higher and higher data rates. As conventional methods like using more bandwidth or higher order modulation types are limited, new methods of using the transmission channel have to be used. Multiple antenna systems (Multiple Input, Multiple Output – MIMO) gives a significant enhancement to data rate and channel capacity. This application note gives an introduction to basic MIMO concepts and terminology and explains how MIMO is implemented in different radio communications standards.

This application note describes a software application that can be utilized in conjunction with Rohde&Schwarz Signal- and Spectrum Analyzers and Signal Source Analyzers to capture and analyze transient signals. The software application takes advantage of the instrument’s IQ memory buffer of up to 705 Msamples to capture and analyze IQ signals in the time domain and / or frequency domain. This is useful for measuring lock time, analyzing radar pulses, finding spurious transients, and other measurements similar in nature to these. This application can be used with R&S®Signal Source Analyzer FSUP and R&S®Signal and Spectrum Analyzers FSQ, FSU, FSG, FSV.

Most of the tests specified in standard TS 34.121 that 3GPP WCDMA user equipment (UE) has to fulfill can be performed solely by the Universal Radio Communication Tester CMU200 universal radio communication tester. Other tests, however, require additional instruments for generating one or more interfering signals, for fading setup or for high dynamic spectrum analysis. This application note shows how easy it is to perform these tests with the remote-control software CMUgo, using the CMU200 in combination with R&S signal generators and R&S spectrum analyzers.
