Calculating Volumetric Site Voltage Standing Wave Ratio in Hybrid Chambers
Volumetric site voltage standing wave ratio in hybrid chambers isolates 3D quiet zone reflections by converting normalized spatial field ripples into linear ratios.
CE Mark Radio Equipment Directive
Meaning
Regulatory framework establishing the safety and radio frequency requirements for equipment that intentionally emits or receives radio waves within the European Union.
Scope Application
Compliance with the ce mark radio equipment directive becomes mandatory for any wireless product entering the European Economic Market. This legal requirement replaces the older R&TTE directive and introduces stricter rules regarding receiver performance and software security. Manufacturers must verify that their hardware does not interfere with other spectrum users while maintaining a high level of resilience against interference itself.
Technical Documentation
Every certified device requires an extensive technical file containing circuit diagrams and bill of materials alongside the test reports. The ce mark radio equipment directive mandates a declaration of conformity that links the product to specific harmonized standards. This folder must remain available for inspection by national authorities for ten years after the last unit is placed on the market.
Marking Specification
Physical products must display the CE logo clearly on the enclosure or the packaging. If the size of the device prevents a legible mark, the documentation or a permanent label on the battery compartment may suffice. The presence of this symbol indicates that the product has undergone the full assessment procedure required for legal sale.
