EMC32 to R&S®ELEKTRA Migration
Using R&S®ELEKTRA Migration Tool
The R&S®ELEKTRA EMC test software is the successor of the R&S®EMC32 EMC measurement software. Like the R&S®EMC32 EMC measurement software, the R&S®ELEKTRA offers a solution that controls complete EMC systems and automates measurements on equipment under test (EUT) that is being tested for emissions (EMI) and immunity (EMS) compliance. It has more features and test types compared to R&S®EMC32.As both software platforms use different file formats, R&S®EMC32 users who upgrade their existing software to the R&S®ELEKTRA platform need to perform a file conversion before migrating their data to the R&S®ELEKTRA platform. This is done by using the R&S®ELEKTRA Migration Tool, which is installed automatically with each R&S®ELEKTRA installation.This Application Note describes how to use the R&S®ELEKTRA Migration Tool (version 4.4 onwards) for converting the backup data into the XML format that can be interpreted by the R&S®ELEKTRA software. It also provides recommended conversion steps (Chapter 5) and troubleshooting tips (Chapter 6). For instructions on migrating the data using R&S®ELEKTRA Migration Tool below version 4.4, refer to the R&S®ELEKTRA user manual. For better user experience, we recommend using the latest software version for migration.This Application Note does not describe the steps to backup data using the R&S®EMC32 or R&S®ES-SCAN software. For procedures on how to do so, refer to their respective manuals.

使用 R&S Space Nexus 创建卫星衰落场景
近几年来逐渐兴起将低地球轨道 (LEO) 和中地球轨道 (MEO) 卫星星座用于宽带数据连接，导致对卫星与用户设备 (UE) 或卫星与地面站 (GS) 之间的信道进行动态模拟的需求迅速增加。卫星信道会受到各种大气效应以及卫星与 UE 之间的相对运动的影响，从而导致频率和电平会根据卫星在天空中的位置而相应变化。因此，相关接收机和其他硬件组件的制造商必须在设计和生产阶段考虑这些影响，以确保提供最佳性能和可靠性。本应用指南将重点概述 R&S Space Nexus 的功能，并解释如何使用该软件根据描述卫星轨迹的给定两行根数 (TLE) 文件来创建真实的衰落文件。之后，本指南将介绍如何根据该文件使用配备 R&S®SMW-K820 自定义动态衰落选件的 R&S®SMW200A 来模拟真实的卫星衰落场景。

Real-time receiver trace export for R&S®ESW
With the wideband extension R&S®ESW-B1000, the R&S®ESW EMI test receiver allows never seen testing speed with up to 970 MHz of FFT bandwidth. External applications can now take advantage of the wide bandwidth. ESW firmware 3.20 adds a new method for exporting trace data from the instrument, regardless if the instrument is equipped with the wideband extension or not. SCPI commands allow live trace export of multiple traces simultaneously. This application note describes the use and applications of SCPI commands to request trace data of up to 4 traces simultaneously from the R&S®ESW receiver, even allowing CISPR detectors. The commands enable trace export while the instrument measures continuously and therefore theoretically enable infinite measurements.

Antenna Beam Characterization of 5G Mobile Devices and Base Stations Using the R&S®NRPM Over-the-Air (OTA) Power Measurement Solution
Radio frequencies in bands around 28 GHz are being discussed as candidates for mobile communications of the fifth generation (5G). Beam steering will be a key feature in the context of 5G. It will be a major challenge to test the beam steering capabilities of base stations and user equipment in every phase from research and development through production. Conducted measurements will be mainly replaced by over-the-air measurements of electromagnetic radiation. Rohde & Schwarz offers the R&S®NRPM Over-the-Air (OTA) Power Measurement Solution that perfectly fits such measurement needs.Part of this solution are the R&S®NRPM-A66 antenna modules. They have integrated diode detectors. Thus, there are no cables between the antenna and the detector as in traditional setups. This avoids high and potentially unknown RF losses. The R&S®NRPM-A66 antenna modules with their integrated diode detectors are factory calibrated, which means that the user does not have to calibrate them to achieve highly accurate measurement results.This application note contains theoretical background on OTA power and pattern measurements. It gives step-by-step instructions for the verification of the power level and the radiation pattern of a device under test (DUT) in comparison to a golden device, and it presents an approach for verifying the accuracy of beam steering.
