Electric (EV) and hybrid electric (HEV) vehicles have both high-voltage (HV) and low-voltage (LV) electric systems. The LV systems are typically unshielded (infotainment, lighting, sensors etc.) and HV systems (battery packs, inverters, electric motors etc.) are shielded. The HV systems ranges from 400 V to 1500 V and the LV system ranges from 12 V to 48 V. The switching operations in HV systems can generate significant electromagnetic noise that may couple into the LV system and degrade performance or cause malfunctions.The HV/LV coupling tests, as defined in CISPR 25, specify the test setup in which HV systems are modified to inject electromagnetic disturbances at predefined levels, depending on the classification of the equipment under test (EUT). These tests also outline methods for measuring the coupling attenuation between HV and LV systems. Additionally, they define procedures for measuring conducted emissions (current and voltage) on LV systems during HV system operation. Furthermore, the standard includes methods to measure radiated noise (electric field) emissions generated when operating HV Systems. The HV/LV coupling tests are emission tests in line with CISPR 25 but some require an immunity test setup to inject disturbance into the system. This application note describes how to set up R&S®ELEKTRA and perform HV/LV coupling attenuation measurements.

Reverberation Chambers (RVC) have become popular as an alternative to Anechoic Chamber (AC) facilities for electromagnetic emission & immunity tests. Unlike AC, RVC reflects waves creating multipath environment. EMC testing using reverberation chamber is accepted in various EMC test standards across different industries. The RVC is cost effective allowing high field strength generation without excessive amplification needs, eliminates the need for complex positioning of antennas and DUTs increasing test speed and simulates real-world electromagnetic environments more accurately. To ensure accurate and efficient testing, specialized EMC test software is required for data acquisition, automation, and analysis. This application note describes how to setup Elektra and perform measurements in RVC.

Best practices for mobile network testing for mission-critical applications

Key Points: Mission-Critical Infrastructure: Military operations require extremely high reliability and availability, as any downtime can result in compromised missions and significant strategic losses. The reliability of communication networks is crucial to ensure seamless execution of military operations. Fundamental requirements: Military applications often require low latency and sustainable latency to ensure real-time communication and control, particularly in situations where split-second decisions can mean the difference between success and failure. This is critical for applications such as command and control systems, surveillance, and reconnaissance. Measurement Techniques: As soon as the radio access network is used, innovative testing methods are needed beforehand to proactively test the network capability and to identify any potential issues. We propose a standard test procedure for the characterization of a network regarding military use-cases that covers a representative set of different, common types of network traffic.

SA Mode According to 3GPP 38.521-1

Device certification for compliance with 3GPP specifications is a crucial step in the launch of 5G NR user equipment (UE). As the demand for high-performance connectivity continues to rise, ensuring that devices meet industry standards is essential for delivering reliable and efficient service. To ensure optimal modem performance, RF pre-conformance testing, also known as design verification, needs to be initiated early in the product development process. This approach enables teams to swiftly identify and address potential issues, minimizing delays and enhancing the overall quality of the final product.The R&S®CMX500 3GPP RF pre-conformance WebGUI solution offers a fast and intuitive platform for executing NR-FR1 Standalone (SA) test cases based on the 3GPP 38.521-1 specification. Its manual verification capabilities make it particularly well-suited for early-stage validation, debugging, and step-by-step verification of test cases, leveraging the comprehensive toolset provided by the R&S®CMX500 WebGUI. Test case procedures are optimized for R&D use cases, while using the most relevant configurations from the specification.This application note serves as a comprehensive guide for R&D professionals, detailing the setup, configuration, execution, and verification of selected 3GPP pre-conformance test cases with just a few clicks in the GUI. Please note that the test steps outlined in this document require the CMX-KC661B license (SA FR1 3GPP RF Test Scenarios), in addition to the NR signaling license CMX-KS600B and the NR FR1 measurement license CMX-KM600. All descriptions, configurations and limits are based on 3GPP TS38.521-1 V18.4.0 (2024-11).
