Multijurisdictional Co Location SAR Evaluation Limits for Portable Host Devices
Multijurisdictional co-location SAR evaluation requires host-level total exposure ratio analysis and spatial decoupling to ensure global market clearance.
Multi-Frequency Scan Validation
Meaning
Advanced testing protocols ensure that sensors maintain their precision when switching between different radio bands. During multi-frequency scan validation, a reference source is measured at several points to confirm that the system correctly identifies the peak energy levels. This step is necessary for devices that use carrier aggregation or multiple wireless protocols at the same time.
Testing across the full frequency range helps to identify any non linear response in the detection system before final data is recorded.
Frequency Coverage
Test plans specify a range of channels that must be sampled to represent the full capability of the device under test. The multi-frequency scan validation process identifies any sensitivity drift that might occur at the edges of the supported spectrum. Testing across a wide range ensures that no hidden peaks are missed during the final compliance evaluation.
Probe Calibration
Sensors used in the process must be characterized for each specific frequency to account for the unique behavior of the antenna. A multi-frequency scan validation compares the live readings against a known standard to confirm the linearity of the sensor. If the values fall outside the allowed tolerance the system requires a full recalibration before proceeding.
Measurement Consistency
Repeated scans at the same frequency points verify that the equipment provides stable results over time. The multi-frequency scan validation reduces the risk of reporting errors caused by thermal drift or mechanical wear in the positioning system. Reliable data is the foundation of any regulatory submission.
