CTK Co. Ltd. Test Report: Spurious Emissions at Antenna Terminal

Test Report 2

This document presents a comprehensive test report detailing the conducted spurious and harmonic emissions at the antenna terminal, conducted by CTK Co., Ltd. The report includes a detailed overview of the testing process, outlining the equipment used, the procedures followed, and the specific settings employed to ensure accurate and reliable measurements. The spectrum is scanned from the lowest frequency generated in the equipment up to a frequency including its 10th harmonic.

The report meticulously documents the levels of carrier and various conducted spurious and harmonic frequencies, measured using a calibrated spectrum analyzer. All out-of-band emissions are measured with a spectrum analyzer connected to the antenna terminal of the EUT while the EUT is operating at its maximum duty cycle, at maximum power, and at the appropriate frequencies. All data rates were investigated to determine the worst case configuration. All modes of operation were investigated and the worst case configuration results are reported in this section.

The document provides a detailed analysis of the test results, including tables and plots illustrating the emission levels across different frequency ranges and under various operating conditions. The report also includes a comparison of the measured emission levels against the regulatory limits, ensuring compliance with the relevant standards.
