The proper use of EMI receiver in advanced laboratories and compliance facilities is important to obtain accurate electromagnetic measurements. Electronic systems are becoming densely connected, high-speed and compact systems, hence increasing the complexity of the undesirable interference. The EMC testing engineers have to depend on precision devices, uniform procedures, and punitive best practic...
In case a product fails the EMC tests, the engineers are not only faced with a problem of identifying the failure, but also finding answers to the question of why the failure has occurred and how to correct the failure and ensure that it minimally fails. Electronic networks in the modern world have switching converters, oscillators, microcontrollers, wireless modules, and cables that create comple...
The calibration of an EMI analyzer happens to be one of the most significant processes in electromagnetic compatibility laboratories and particularly, high sensitivity EMC, where even the slightest error in measurements influences the compliance determination. Engineers use accurate measurements to determine the level of interference, source of emission and to determine the performance of a produ...
The need to obtain an electromagnetic compatibility has now become a fundamental need in virtually all electronic devices, and such need has also made the need to have an accurate EMI test receiver system very pertinent. The current EMC testing systems use special receivers to identify, measure and process undesired electromagnetic disturbances. These are disturbances which are not always noticeab...
The modern electronic devices use the environment abundant in the electromagnetic energy, and the reaction to such fields is somehow observed in each circuit, cable or component. It is against this reason that the manufacturers must make sure that their designs do not produce an adverse interference and are robust enough to confront external inhibitions. This EMI compliance testing guide gives a f...
Modern wireless equipment relies on a high level of performance of the antenna to ensure constant communications, precise data transmission, and general durability of the equipment. Since products are incorporating Bluetooth, WiFi, GPS, 5G modules and many RF systems in compact formulations, engineers must still make sure that the antennas are effective and are not emitting unnecessary noise. In t...

Abstract With the widespread application of electronic equipment, electromagnetic compatibility (EMC) has become a key indicator in product design and production. This paper takes the LISUN EMI-9KB EMI Receiver Test System as the research object, and analyzes in detail its technical characteristics, testing capabilities and application scenarios. The system adopts a fully enclosed structure and hi...
Abstract: With the rapid development of electronic technology, the number of electronic devices is increasing daily, and their operating frequencies are becoming higher, leading to an increasingly complex electromagnetic environment. Electromagnetic interference (EMI) issues have become a critical factor affecting the reliability and safety of electronic equipment. Therefore, conducting strict Ele...
Abstract Conducted emissions, a critical component of electromagnetic interference (EMI), refer to the propagation of unwanted electromagnetic energy through conductive media such as power lines, cables, or connectors. Accurate measurement of conducted emissions is essential for ensuring electronic devices comply with international standards, avoiding interference with other equipment, and maintai...
Introduction Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) testing are critical processes in the development and certification of electronic devices. These tests ensure that devices operate reliably in their intended environments without causing or suffering from electromagnetic disturbances. LISUN, a leading provider of testing equipment and solutions, plays a pivotal...
Introduction As electronic devices become increasingly complex and ubiquitous, electromagnetic compatibility (EMC) and electromagnetic interference (EMI) have emerged as critical factors in the design, manufacturing, and operation of modern electronics. Whether in consumer electronics, industrial control systems, or aerospace applications, EMC/EMI issues can disrupt system performance, compromise ...
