Electromagnetic Compatibility Laboratory
LGT has established an independent and complete testing system, including a 3-meter French anechoic chamber, RF full-wave anechoic chamber, RS test system, anti-interference test room, and shielded room. The testing instruments are advanced and are manufactured and constructed by well-known international companies in the industry such as Germany's Rohde & Sehwar z, TESEQ, Schwarzbeck, Switzerland's EMTEST, HAEFELY, EMC Partner, and the United States' Agilent and FCC. The technical team is composed of a group of professionals and expert consultants who have been engaged in EMC detection, countermeasures, and test work for many years. It can provide a wide range of electronic companies with everything from PCB Layout design, circuit parameter calculation, component specification selection to complete machine system integration, product testing, Countermeasures and test one-stop service.

Electromagnetic Compatibility Laboratory
The electromagnetic compatibility (EMC) laboratory has a 3-meter anechoic chamber and a shielded room that are commonly used in international standards. The test systems are provided by world-renowned manufacturers. The main EMI test systems include: harassment power, conduction harassment, radiation harassment, high-frequency radiation spurious and radiation spurious automatic test systems for GSM, CDMA, WCDMA, LTE, 5G NR equipment. The main test systems of EMS are: radio frequency immunity, harmonic/voltage fluctuation and flicker, electrostatic discharge immunity, electrical fast transient pulse group immunity, surge immunity, conduction immunity, power frequency magnetic field immunity Interference, voltage drop, sag and interruption immunity, lightning strike automatic test system.
The current testing capabilities and the testing standards met are:
