D3500V2 SAR Validation Source Calibration Certificate

IHDT56AV4_Part 1_SAR_Appendix H_Reference SAR_Part5-11

This document presents the calibration certificate for the D3500V2 SAR validation source, serial number 1037. The calibration was performed by Schmid & Partner Engineering AG, an accredited Swiss calibration laboratory, and is traceable to national standards. The certificate details the calibration procedure, which adheres to QA CAL-22.v7, specifically designed for SAR validation sources between 3-10 GHz. All measurements were conducted in a controlled laboratory environment, maintaining a temperature of 22 ±3°C and humidity below 70%.

The calibration process involves assessing antenna parameters with tissue simulating liquid (TSL), measuring return loss, and determining SAR values. The source is mounted in a touch configuration below the center marking of a flat phantom. The return loss parameter ensures low reflected power, while SAR measurements are normalized to an input power of 1 W at the antenna connector. The certificate includes SAR values averaged over 1 cm³ and 10 cm³ of Head TSL, along with associated uncertainties. The reported uncertainty is stated as the standard uncertainty multiplied by a coverage factor of k=2, corresponding to a coverage probability of approximately 95%.

This certificate serves as evidence of the validation source's calibration status and its suitability for accurate SAR measurements in compliance with relevant standards.
