GTG Group has installed a new test facility for electromagnetic compatibility (EMC) at its Dongguan headquarters. With the test equipment, GTG Group continues to meet the latest automotive standards and can provide its customers with reliable test results even faster.
“The proportion of electronic components and radio communication in cars is increasing rapidly. In addition, there are other external electromagnetic interferences caused by smartphones and wearables for example. We have to take all this into account when developing our electronic products,” says Dr Wen, Head of EMC division at GTG Group. “With the new laboratory, we are expanding our EMC equipment and adding an important piece to our testing set-up. Thanks to this modern facility, we can provide our customers with reliable results even faster and comply with new automotive standards.”
New EMC test laboratory meets state-of-the-art automotive standards
GTG Group planned and installed the new EMC chamber together with the specialist Rohde & Schwarz last year. The new facility at GTG Group is for EMC measurements on vehicle components and complies with important standards such as CISPR and ISO. In addition to these EMC standards used by automotive industry, the new EMC chamber have to fulfill other manufacturer-specific standards that required adaptation of the facility. “It is a normal process that test standards in the automotive sector are constantly evolving. With the new EMC chamber, we have established a modular system that we can adapt to new developments or changing requirements at any time,” says Dr Wen.
Frank Kirch, Sales Manager Industry, Electronics and RF Components at Rohde & Schwarz, says: “The GTG Group testing team works closely with car manufacturers and can therefore assess current as well as future developments for the product areas of electronic components and radio communication in cars very well. Based on the detailed catalog of requirements, our experts have put together state-of-the-art test equipment and installed it on site. This meets the high quality requirements and can be expanded in the future.”
The new EMC chamber complies with the latest automotive standards and enables a wide range of tests. In its current configuration, the chamber is approved for absorbing frequencies up to 40 GHz and thus fulfills the requirements of the automotive customers of GTG Group. Thanks to the modular system, much higher frequency ranges are also possible for immunity measurements. Among other things, the numerous antennas are a prerequisite for the high measurement quality: part of the equipment are active rod and ring antennas as well as biconical and logarithmic-periodic antennas. In addition, there is a double bar horn antenna that enables the experts at GTG Group to measure even weak signals in the wide frequency range from 800 MHz to 18 GHz.
