CMQ500

Oct 18, 2021

Rohde & Schwarz announced today the next breakthrough in 5G data performance: With support of Qualcomm Technologies, Inc., Rohde & Schwarz has validated 10 Gbps end-to-end (E2E) IP data performance using its R&S CMX500 5G radio communication tester platform. The setup was powered by Snapdragon® X65 5G Modem-RF System, the world’s first 3GPP Release 16 modem-RF system with Qualcomm® QTM545 mmWave Antenna Module.

The R&S®CMQ shielding cube is a compact shielding solution for RF parametric testing. The turnkey chambers for direct far field over-the-air (OTA) measurements are ideal for testing antennas, modules and devices throughout the entire lifecycle under comparable measurement conditions: from product design to the production line.

As wireless network operators roll out 5G NR in the millimeter wave spectrum, it is critical to ensure continued reliability of E911 calls and accurate determination of location in mobile devices.

校准和验证解决方案

超宽带 (UWB) 技术是针对未授权频段中设备间通信的近程宽带无线电技术。这是一种射频定位技术，能够准确安全地测量移动设备之间的对等距离、可靠地抵抗干扰、与其他无线电通信系统适当共存且能耗非常低。UWB 被广泛用于各种不同应用，例如资产跟踪、安全支付、个人追踪器、实时定位服务以及无钥匙车辆访问和启动等。ABI Research 预测，2026 年 UWB 设备的年出货量将超过 10 亿，届时几乎所有发运的智能手机都将支持 UWB 服务。UWB 设备和其他无线产品一样，一般可以采用两种方法进行测试：一种是传统的传导测试模式，测试与测量设备和被测设备 (DUT) 之间进行有线射频连接，另一种是使用空口 (OTA) 电波暗箱的 OTA 测试模式。考虑到成本、空间和复杂性问题以及能否直接接触产品的射频连接器，有时无法或无需执行传导测试。这种情况下必须采用 OTA 测试方法。OTA 测试还能够反映出被测设备在实际条件下的使用情况。本应用指南描述了 R&S® OTA 测试解决方案，涵盖在无线自动化测试 (WMT) 环境中执行的发射机 (Tx)、接收机 (Rx) 和飞行时间 (ToF) 测试。本指南的所有测量结果均基于恩智浦的 Trimension™ NCJ29D5 UWB 汽车电子 IC。

本カタログでは、当社の無線（OTA）およびアンテナテストソリューションの概要を紹介します。お客様は、これらのソリューションをラボに導入することで、可能性の限界を押し広げることができます。

Feedthroughs are used to run cables from the outside into a shielded environment such as an RF shielded box or an OTA chamber. This is done to maintain the shielding effectiveness of a given environment and prevent leakage of RF radiation into or out of the chamber.

天线的特性和质量会显著影响OTA测试系统的整体测量准确度，因此选择合适的天线非常重要。下文简要介绍了常见的OTA天线及其关键参数。 联系我们了解更多详细信息。

Since antenna characteristics and quality have a major influence on the overall measurement certainty in OTA test systems, selecting the right antenna is critical. The following is an overview of the most common OTA antennas and their key parameters. Contact us for more details.
