Surge Testing on Data Cables
Introduction In many EMC and safety standards, surge testing is required for data cables exceeding 30 meters in length. This requirement is crucial for ensuring the resilience of electronic systems against transient overvoltages. But what justifies this length threshold? Here we explore the physical and electrical principles that necessitate surge testing for long data cables. […]
Step-by-Step Guide to Obtain FCC and ISED Certification for Radio Devices
Step 1: Determine the Regulatory Framework FCC and ISED regulate radio devices under different categories: FCC Certification: Required for devices operating on licensed and unlicensed frequency bands, such as Wi-Fi, Bluetooth, and cellular modules. ISED Certification: Devices sold in Canada must comply with ISED’s technical standards, known as Radio Standards Specifications (RSS). Use the […]
Conducted Emission
Understanding Conducted Emissions Conducted emissions are a crucial aspect of electromagnetic compatibility (EMC) testing. They refer to the unwanted electrical noise or interference that is conducted along power or signal lines, which can potentially disrupt other electronic devices. Why is Conducted Emission Testing Important? Testing for conducted emissions ensures that electronic products do not […]
Automotive EMC Testing
Importance of EMC Testing in Automotive Industry 1. Safety Preventing Malfunctions Vehicles and ESAs must not emit electromagnetic interference that could cause failures in braking, steering, engine control systems, and power management modules. As vehicles integrate autonomous driving technologies, preventing EMI is more critical than ever. Protecting Occupants and Road Users Safety-critical electronic systems […]
All about EMI filters
Power converters are the unsung heroes of modern electronics, quietly and efficiently transforming electrical energy to power everything from smartphones to electric vehicles. But there’s a hidden challenge in their design: electromagnetic interference (EMI). EMI is essentially electrical noise generated by the rapid switching of power semiconductor devices within the converter. This noise can disrupt […]
How to Choose a Best-Fitted EMC Lab
As a manufacturer, ensuring your products meet the required electromagnetic compatibility (EMC) standards is crucial. Failing to pass EMC tests can delay your product’s release, cause compliance issues, or even lead to costly recalls. However, achieving accurate and reliable results from EMC testing depends on several factors, including the environment in which testing is conducted, […]
EMC and RF Testing in a Nutshell
What Is EMC Testing? EMC testing evaluates an electronic device’s ability to function in its electromagnetic environment without causing or experiencing unacceptable interference. It consists of two primary aspects: Emissions Testing: Measures the electromagnetic energy emitted by a device to ensure it does not interfere with other equipment. Immunity Testing: Assesses a device’s […]
