EMC electromagnetic compatibility test

1. Introduction

Electromagnetic compatibility (EMC) mainly studies the interference and anti-interference issues of electronic and electrical products, that is, how to make various electronic and electrical devices, equipment or systems work normally without interfering with each other and achieve compatibility.

EMC is divided into two categories: EMI and EMS.

EMI refers to the emission characteristics of a device: the characteristics of a device emitting electromagnetic interference to the outside.

EMS refers to the immunity of equipment: the ability of equipment to resist external electromagnetic interference. The more sensitive the equipment, the worse the immunity.

IV. EMC Electromagnetic Compatibility Test Sample Requirements

EMC electromagnetic compatibility testing requires that the product is in normal working condition. When the manufacturer arranges to send samples, the corresponding input and output loads and accessories must be sent together. The corresponding wiring instructions and installation requirements must be sent to the laboratory for confirmation in advance. If the test software needs to be installed, the software instructions must be sent to the laboratory together. Two sets of conventional supporting products are sufficient.

5. EMC electromagnetic compatibility test cycle

The electromagnetic compatibility test can be completed in about 2-3 weeks after receiving the test samples and fees. If there are special requirements, it can be expedited. If the test fails and rectification is required, the cycle will be postponed.
