This document presents the test results for DTS bandwidth and power spectral density measurements conducted on the MT7663 wireless module. The tests were performed on April 24, 2025, under ambient conditions of 22°C and 48% relative humidity. The testing was conducted by Evan Ouyang. The report includes detailed data for various 802.11 modes (b, g, n, and ax) with different channel bandwidths (20MHz and 40MHz) and modulation schemes (SISO). The measurements were taken across multiple channels (2412MHz, 2437MHz, 2462MHz, 2422MHz, and 2452MHz) to ensure comprehensive evaluation.
The results demonstrate that the MT7663 module complies with the FCC's DTS bandwidth and power spectral density limits. All tested configurations passed the required limits, as indicated in the test result tables. The report includes detailed graphs illustrating the occupied bandwidth and power spectral density for each test mode and channel. This data provides a comprehensive overview of the module's performance and compliance with regulatory requirements.
