Meaning
Procedure to verify the amplitude and phase consistency of an array of sensors used in specific absorption rate measurements. Successful vector probe system calibration ensures that every probe in the network reports identical values when exposed to the same signal intensity. This check removes the errors caused by cable aging or temperature variation in the receiving electronics.
Reference Measurement
Signal sources with known output levels are positioned at precise intervals above the sensor grid. During vector probe system calibration, the software adjusts the scaling factors for each individual detector to match the expected physics models. Any deviation in these coefficients requires an inspection of the probe integrity or connector cleanliness.
Traceability Document
Logs from this test serve as the primary evidence that the lab equipment is fit for official regulatory work. Because vector probe system calibration is performed at fixed maintenance intervals, it creates a historical record of system stability and wear. Results that fall outside defined ranges force a complete pause in device testing sequences until repairs are completed.
Array Uniformity
Sensitivity maps show how well the fixed array handles variations in field orientation and polarization. Quality vector probe system calibration maintains the accuracy of the spatial reconstruction algorithm, which is essential for defining peak energy points in human phantom models. High density arrays require longer calibration times to address the interactions between neighboring elements.
