This document presents a detailed analysis of Power Spectral Density (PSD) measurements conducted by SGS-CSTC Standards Technical Services Co., Ltd. Shenzhen Branch. The report, identified by number SZCR250200054404, provides comprehensive data and graphical representations of PSD for various 802.11 wireless communication standards.
The analysis covers a range of frequencies and configurations, including 802.11a, 802.11n (HT20 and HT40), and 802.11ac (VHT20) standards. Measurements were taken at different center frequencies such as 5180 MHz, 5200 MHz, 5240 MHz, 5260 MHz, 5300 MHz, 5320 MHz, 5500 MHz, 5580 MHz, and 5720 MHz, among others. The data includes detailed plots of PSD levels in dBm/MHz against frequency, along with key parameters like center frequency, span, RBW, VBW, detector type, and sweep settings.
The report also specifies the antenna used (Ant1 or Ant2) and the operating mode (NTNV). Maker values indicating specific frequency points and their corresponding PSD levels are provided for each test case. This document serves as a valuable resource for understanding the spectral characteristics of wireless signals under different operating conditions.
