More and more mobile radio networks implement remote radio equipment (RE) that is connected to the base station main unit via a digital interface using standardized transmission protocols such as CPRI. For testing RE devices Rohde & Schwarz offers a complete test solution based on the R&S®EX-IQ-BOX [Model K04]. This key component is a configurable digital interface module that is used to connect Rohde & Schwarz test equipment to a RE under test using CPRI data transmission. This application note explains in detail the instrument setup and configuration needed to successfully test your remote radio head.

R&S®Server-Based Testing helps reduce test times for workloads that can be parallelized. 5G New Radio (5G NR) multicarrier signals are an ideal workload because each component carrier can be analyzed independently and in parallel. In an example EVM measurement, scenario test times are reduced significantly even when receiving I/Q data from just a single instrument.

Multiple input multiple output (MIMO) technology is an integral part of 3GPP E-UTRA long term evolution (LTE). As part of MIMO, beamforming is also used in LTE. This application note provides a brief summary of the transmission modes (TM) in LTE and describes the beamforming measurements for base stations (BS) and user equipment (UE). The T&M options using various Rohde & Schwarz instruments are also presented.

The LTE technology as specified within 3GPP Release 8 was first commercially deployed by end 2009. Since then the number of operators implementing the technology is strongly increasing around the globe. LTE has become the fastest developing mobile system technology. The same way GSM and WCDMA have been enhanced with additional features over time, LTE is continuously worked on. Initial enhancements have been included in 3GPP Release 9 and are described in this white paper.

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.

This application notes introduces the Multi-Standard Radio Analyzer function of the R&S®FSW and shows how it performs the measurement on multi-standard radio transmitters. It reveals interactions caused by the coexistence of signals of different cellular standards and localizes the root cause. With an example of a base station signal consisting of three radio access technologies (GSM/WCDMA/LTE FDD) it shows how easy interactions can be found. The R&S®FSW is the ideal tool for trouble shooting tasks with its combination of a large bandwidth and the versatile Multi-Standard Radio Analyzer in one measurement instrument.

Automating measurement setups is advantageous for multiple reasons. It saves time in case of repeated measurements and in hazardous environments, instruments can be operated from a distance. The measurements are repeatable because they are always performed with a defined procedure, leading to higher test confidence.But in remote control applications, users often perceive synchronization and binary transfers as challenging. Therefore, this application note focuses on binary transfer of data to and from the instrument and shows code example to demonstrate the ease of use.
