Introduction
Radiated interference tests are crucial for evaluating the electromagnetic emissions of electronic devices and ensuring that these emissions stay within permissible limits as prescribed by EMC standards. The LISUN EMI-9KB EMI Test Receiver is a highly reliable system used for measuring conducted and radiated interference. This paper delves into the technical principles, methodology, and application scenarios of radiated interference tests with a focus on the LISUN EMI-9KB system.

Principles of Radiated Interference Test
Radiated interference tests are designed to detect unintended electromagnetic emissions from devices under test (DUT). These emissions, if not controlled, can cause malfunctions in other electronic systems. The process typically involves:

• Test Environment Setup: Conducted in an anechoic chamber or open-area test site to eliminate external interference.
• Equipment: Includes a test receiver (such as LISUN EMI-9KB), antennas, and ancillary devices.
• Test Procedure: The DUT is powered and operated in various modes while the receiver captures emissions across specified frequency ranges.

Features of the LISUN EMI-9KB EMI Test Receiver
The LISUN EMI-9KB system is engineered to meet international standards such as CISPR 16-1, GB/T 6113, and EN 55016. Key features include:

• Frequency Range: 9 kHz to 30 MHz for conducted emissions and 30 MHz to 1 GHz for radiated emissions.
• High Sensitivity: Detects low-level emissions with a preamplifier.
• Versatility: Suitable for testing household appliances, lighting systems, and industrial equipment.
• User-Friendly Interface: Simplifies configuration and data analysis.

Applications of Radiated Interference Tests
1. Consumer Electronics
Ensures compliance with EMC standards to prevent interference with nearby devices such as smartphones, televisions, and routers.

2. Automotive Industry
