SGS-CSTC System Performance Check: 450 MHz Head

Appendix A

This document presents the detailed results of a system performance check conducted by SGS-CSTC Standards Technical Services (Suzhou) Co., Ltd. The check was performed on a 450 MHz head using a D450V3 device (Serial: 1103) to ensure the accuracy and reliability of SAR measurements. The communication system employed was CW (0) with a duty cycle of 1:1.

The testing environment utilized HSL450 medium with specific parameters: f = 450 MHz, σ = 0.891 S/m, εr = 42.821, and ρ = 1000 kg/m³. A flat section phantom was used for the measurements. The DASY5 configuration included an EX3DV4 probe (SN3801), DAE4 electronics (Sn1245), and a SAM 7 phantom (Serial: 1702). The system was calibrated on 2024/06/20 and 2024/06/05, respectively.

The area scan and zoom scan results are presented, including SAR values and graphical representations. The maximum SAR measured was 1.20 W/kg. The report provides comprehensive data for assessing the system's performance and validating its suitability for SAR testing.
