Free Space Dielectric Property Extraction for Automotive Radar Polymer Enclosures
Precision W-band free-space extraction of polymer permittivity prevents radar boresight shift and avoids costly Class II Permissive Change re-testing delays.
TELEC Giteki Testing
Meaning
Japanese radio law certifications verify that wireless devices meet the specific technical standards required for operation within the national frequency spectrum. The telec giteki testing process involves a thorough review of the radio characteristics and the construction design by a registered certification body. Obtaining this mark is a requirement for anyone wishing to sell or use radio equipment in Japan.
Spectral Mask
Transmitters must operate within tight limits to prevent interference with other wireless services in the crowded Japanese airwaves. During telec giteki testing, laboratory equipment measures the occupied bandwidth and the strength of the emissions outside the main frequency. These measurements ensure that the device complies with the technical regulations for its specific equipment class.
Output Power
Controlling the signal strength of a device prevents it from overwhelming other nearby receivers and ensures the fair use of the spectrum. The telec giteki testing procedure checks the transmission power and the tolerance of the frequency generator under different voltage conditions. This data is recorded in the formal test report that is submitted for the final certification.
Certificate Retention
Once the device has passed the evaluation, it is issued a unique identification number that must be displayed on the product. Records of the telec giteki testing must be kept by the manufacturer to provide evidence of compliance in the event of a market audit. This certification remains valid as long as the hardware and software that affect the radio performance are not modified.
