This document is a calibration certificate for the D3500V2 dipole validation kit, serial number 1104. The calibration was performed by the China Telecommunication Technology Labs (CTTL) in collaboration with SPEAG, adhering to national standards and ensuring traceability to physical units of measurement (SI). The certificate documents the procedures, equipment, and results of the calibration process, which is crucial for accurate Specific Absorption Rate (SAR) measurements.
The calibration was conducted in a controlled laboratory environment, maintaining a temperature of 22±3°C and humidity below 70%. Key equipment used in the calibration process is listed, including power meters, sensors, reference probes, and signal generators, all with valid calibration certificates. The calibration procedure followed is FF-Z11-003-01, specifically designed for dipole validation kits. The calibration date is October 21, 2024.
The certificate includes details on the antenna parameters with Head TSL (Tissue Simulating Liquid), impedance, return loss, and electrical delay. SAR results are presented for both 1g and 10g averages, normalized to a 1W input power. The document also includes measurement conditions, head TSL parameters, and additional assessments outside the scope of CNAS L0570. The certificate is issued on October 30, 2024, and is valid only in its entirety with written approval from the laboratory.
