SAR System Performance Check Report

Introduction to SAR Testing

Specific Absorption Rate (SAR) testing is crucial for evaluating the radio frequency (RF) energy absorbed by the human body when using wireless devices. This report details system performance checks conducted by JianYan Testing Group Shenzhen Co., Ltd. to ensure the accuracy and reliability of SAR measurements.

Testing Overview

JianYan Testing Group Shenzhen Co., Ltd. performed these system checks as part of the evaluation process for mobile devices. The tests involved using calibrated dipole antennas to verify the SAR measurement system's performance across a range of frequencies relevant to wireless communication standards. The primary device context for these checks is the INFINIX X6838 mobile phone.

The following dipole models were utilized for system performance checks:

• D750V2
• D835V2
• D1750V2
• D1900V2
• D2450V2
• D2600V2
• D3500V2
• D3700V2
• D3900V2

These checks were performed at frequencies ranging from 750 MHz to 3900 MHz.

Key Performance Check Results (SAR(1g))

The following table summarizes the measured SAR(1g) values obtained during the system performance checks:
