Dipole Calibration Certificates by CTTL for CAICT

24T04Z103003-002_Part 2_SAR_3

This document contains a collection of dipole calibration certificates issued by the China Telecommunication Technology Labs (CTTL) for the China Academy of Information and Communications Technology (CAICT). The certificates detail the calibration procedures and results for various dipole models used in Specific Absorption Rate (SAR) testing. The calibrations were performed in accordance with international standards, ensuring traceability to national measurement standards.

The certificates cover dipole models operating at frequencies of 1750 MHz, 1900 MHz, and 2600 MHz. Each certificate includes detailed measurements of antenna parameters, such as impedance and return loss, as well as SAR values measured in head tissue simulating liquid (TSL). The calibration process involves precise measurements of the dipole's performance under controlled laboratory conditions, with environmental parameters carefully monitored and maintained. The reported uncertainties are stated as the standard uncertainty of measurement multiplied by a coverage factor of k=2, corresponding to a coverage probability of approximately 95%.

The accreditation by the Swiss Accreditation Service (SAS) further validates the reliability and accuracy of the calibration services provided by CTTL. The certificates are essential for ensuring the validity of SAR measurements performed on wireless communication devices, contributing to the safety and compliance of these devices with regulatory requirements.
