Electromagnetic compatibility (EMC) testing is essential for new electronic products. The global expansion of industries fuels the demand for new electronics. With higher demand for products comes the need for more EMC Chambers testing facilities. The growth of automotive and Electric Vehicle (EV), aerospace, defense, telecom, AI servers, and the upcoming 6G technology will bring an increased demand for EMC testing.
Modern electronic systems incorporate many components and operate at higher frequencies. Systems with more components are more susceptible to interference that results in degraded service and unsafe systems. EMC testing chambers are necessary to provide a controlled laboratory environment to test products for compliance with international standards.
All electronic systems employ wireless communication, rapid information processing, intelligent programs, and automation. These systems are heavily dependent on radar. The international demand for these systems accelerates the need for more EMC testing facilities.
What is an EMC Chamber?
EMC chambers help isolate external interference to create a noise-controlled environment. These chambers allow electromagnetic emissions to test a product’s immunity.
Isolation of external electronic noise enables product testing for electromagnetic interference (EMI), electromagnetic compatibility (EMC) compliance, Radio Frequency (RF) shielding, Antenna, Wireless communication, and other product certification testing.
Many industries require EMC testing to meet international standards. These standards include CISPR, MIL-STD, ISO, FCC, and IEC.
The Growing Demand for EMC Chambers
