Meaning
Multi-sensor antenna arrays measure both the amplitude and the phase of the electromagnetic field near a radiating device to reconstruct the complete three-dimensional energy distribution. Vector probe system represents this high-speed measurement setup that replaces traditional single-probe mechanical scanners in Specific Absorption Rate testing laboratories. By capturing the complete vector field information across a grid of sensors simultaneously, this system reduces the time required to complete a compliance scan from hours to seconds.
Hardware developers employ this rapid testing capability during the prototyping phase to evaluate the radiation characteristics of new enclosure designs.
Sensor Array
A matrix of miniature field probes is embedded within a curved phantom shell that matches the human body shape. The operation of a vector probe system depends on these fixed sensors to capture the field distribution without any moving parts. This static design eliminates mechanical wear.
Signal Reconstruction
Advanced algorithms process the multi-channel sensor outputs to calculate the localized Specific Absorption Rate. In a vector probe system, the software reconstructs the three-dimensional field by solving the electromagnetic wave equation from the boundary data. This calculation occurs in real time.
Throughput Measurement
Fast verification cycles enable continuous testing on the production line. Deploying a vector probe system allows manufacturers to perform quality control scans on every assembled module. This throughput ensures that no defective sub-assembly enters the distribution channel.
