AVL adds Rohde & Schwarz GNSS stimulation to vehicle test environmentGNSS signals (for example GPS signals) are of major importance for positioning and tracking, orientation and safety-related information, such as congestion, in road traffic. A collaboration between AVL and Rohde & Schwarz, two of the world’s leading providers of measuring and automotive testing systems, now permits the reproduction of realistic GNSS reception conditions for testbed vehicle testing. As a result, users can reliably test all aspects of GNSS-based vehicle positioning – a core functionality of autonomous vehicles.

Rohde & Schwarz supports i14y Lab Summit 2022 with practical demos of its O-RAN test solutionsAt the recent i14y Lab Summit 2022 in Berlin, Rohde & Schwarz has showcased as one of the lab’s partners its proven and powerful measurement instruments used to verify the conformance of O-RAN Radio Units and the end-to-end network performance. Led by Deutsche Telekom, the i14y Lab is an industry consortium aimed at accelerating network disaggregation and Open RAN by building a European and German ecosystem of vendors and system integrators. Through early stage collaboration with open lab partners and customers, Rohde & Schwarz is able to adopt its portfolio in accordance with new test requirements.
This application note addresses the diverse possibilities of interoperability between Rohde & Schwarz power sensors and Rohde & Schwarz signal generators. All current and many legacy Rohde & Schwarz signal generators offer the capability of directly connecting power sensors. This enables power measurements without the need of a base unit or separate PC to display the readings. Furthermore, sensors can be used for special tasks like filling a user correction table or continuously controlling levels at crucial points in the measurement configuration.

手动和自动无线共存测试的分步操作指南
截至 2020 年末,全球共有 200 多亿台物联网 (IoT) 设备使用授权和未授权频段。随着越来越多的人选择更加智能互联的生活方式,预计未来数年将稳定保持这种增长趋势。射频环境将变得更加繁忙和具有挑战性。为了探究射频频谱的复杂性,罗德与施瓦茨在 2021 年发布了一本白皮书,介绍了在一天当中的不同时段观察多个地点的射频频谱活动。罗德与施瓦茨根据人口密度、已知射频发射机的数量和频率选择了不同的观察地点。白皮书指出,由于大部分 IoT 设备使用未授权频谱,因此 ISM 频段的平均通道利用率更高。白皮书建议,执行无线共存测试时,测试条件应反映出设备的预期射频操作环境。否则,射频性能表征仅能反映实际操作环境中不存在的理想条件。由于有时候无法在实际环境中测试所有设备,因此需要设置相关测试方法以尽可能重现实际环境。这将有助于了解射频设备的接收机在不同射频条件下的特性。白皮书还建议执行测量以了解设备在更为严峻的未来频谱环境中的特性。因此,还需要全面表征射频接收机处理带内和带外干扰信号的能力。关于确保无线共存性能的监管合规性要求,ANSI C63.27 是目前唯一发布的测试标准,针对如何执行设备的共存测试提供了相应指南。干扰信号可能导致失败并影响用户健康,致使测试非常复杂。标准还为设备制造商提供了相关指南,包括测试设置、测量环境、干扰信号类型和策略、使用关键性能指标 (KPI) 的物理层性能质量测量参数和表征端到端功能性无线性能 (FWP) 的应用层参数。本应用指南遵循 ANSI C63.27-2021 版标准针对测试设置、测量参数和干扰信号提供的相应指南。指南将明确说明如何配置罗德与施瓦茨的标准化测试仪器以生成所需信号和意外干扰信号,并执行测量以监测设备的 PER、Ping 延迟和数据吞吐量性能。本应用指南通过分步说明介绍如何使用传导和辐射方法执行测量。指南描述了手动和自动仪器配置方法。自动化脚本以 Python 脚本语言编写,并可随本指南一起免费下载。运行脚本所需的官方 可通过 PYPI 数据库获取。

面向生产和研发的综合性测试解决方案指南
小基站是一种紧凑型基站,和常规的宏基站相比体积更小、传输功率更低。小基站的覆盖范围相对较小,承载的用户量也更少。一般而言,小基站能够集成到现有的移动网络中。无线接入技术持续演进,小基站的作用也随之不断变化。在 2G/3G 时代,小基站被用于在极端情况下提供覆盖。在之后的 LTE 时代,基站网络不仅提供覆盖,还提供容量。小基站被用于根据需要提供附加容量,不额外增加频谱。在当下的 5G 时代,网络运营商采用关键的密集化策略来提供流畅一致的 5G 服务,这同样需要保障网络覆盖、容量和性能。对于需要部署 5G 毫米波 (mmW) 的应用,考虑到毫米波的传播特性,可以通过小基站有效增加基站密度。在本应用指南中,我们将探讨产品生命周期中的小基站测试,并使用无线电综测仪 R&S®CMP200 和 OTA 暗箱 R&S®CMQ200 重点针对拆分选项 6 讨论空口 (OTA) 环境中 FR2(频率范围 2,毫米波频段)的小基站被测设备 (DUT) 的生产测试解决方案。指南的第二部分将更加深入地介绍典型研发测试应用中使用的测试解决方案。
