This document presents the calibration certificate for the EX3DV4-SN:7838 device, issued on November 20, 2024. The certificate provides detailed information regarding the calibration process, including the communication system names, groups, PAR (Peak to Average Ratio) values in dB, and the associated uncertainty (UncE) with a coverage factor of k=2. The calibration was performed according to established standards and procedures to ensure the accuracy and reliability of the device's measurements.
The certificate lists a wide range of communication systems, primarily focusing on IEEE 802.11 (WiFi) and LTE-TDD technologies. Each system is characterized by its specific parameters, such as modulation schemes (QPSK, 16-QAM, 64-QAM), bandwidths, and duty cycles. The PAR values indicate the dynamic range of the signals, which is crucial for accurate power measurements. The uncertainty values provide an estimate of the potential error in the measurements, ensuring that the device meets the required performance specifications.
This certificate is essential for maintaining the traceability and validity of measurements performed using the EX3DV4-SN:7838 device. It serves as a record of the device's performance at the time of calibration and provides a basis for assessing its ongoing accuracy and reliability.
