Radio Frequency Testing

Radio Frequency (RF) Testing of Electronic Devices and Components

Electromagnetic Compatibility (EMC) and Radio Frequency (RF) testing, including Over The Air Testing (OTA) and Specific Absorption Rate (SAR) testing, closely analyses the ability of devices to operate safely and effectively when in proximity to other electronic devices or in the presence of electromagnetic emissions. Talk to our experts to get RF and EMC solution for your products. 

We offer comprehensive testing facilities for related to testing of communication products and other product categories related to electromagnetic compatibility. HTW RF Laboratory has advanced and complete wireless testing equipment, and all of them are made by internationally renowned manufacturers such as German R & S, Aeroflex in the United States, and ESPEC in Japan. At the same time, HTW radiating sites and conduction sites are designed and operated in strict accordance with CISPR16 and ANSI C63.4, and obtained FCC, IC and VCCI site registration qualification, providing a powerful double guarantee for the accuracy and stability of RF test data.
