Meaning
High-precision electromagnetic field sensors measure the specific energy absorption rate inside a simulated head or body model. The dasy6 probe is the industry-standard instrument used to scan the electric fields within the tissue-equivalent liquid. This measurement is critical for verifying that wireless devices comply with international safety limits.
Measurement Accuracy
Sensor elements are arranged orthogonally to minimize isotropic deviation. This design enables the instrument to measure the electric field strength correctly regardless of the wave polarization. The resulting data is transmitted via a fiber-optic link to prevent any interference with the measured field.
Calibration Routine
Annual calibration of the device at a certified laboratory establishes the correction factors for different frequency bands. The technician determines the sensitivity of the dipoles by exposing them to a known field strength inside a waveguide. These parameters are stored in an electronic chip embedded in the connector of the probe.
Mechanical Interface
Secure mounting is required to connect the instrument to the robot arm used for the spatial scan. A precise mounting system prevents any slippage that would introduce positional errors during the measurement. When the robot moves the probe through the liquid, the mechanical connection must withstand the drag forces without deflecting, which ensures that the grid measurements remain accurate to within a fraction of a millimeter.
This structural rigidity is essential for the repeatability of the automated scans required by international compliance protocols.
