This report details the passive antenna testing performed on the SKULLCANDY CRUSHER PLYR 720 Wireless Transmitter, model number SMDGZ. The tests were conducted by SGS-CSTC Standards Technical Services Co., Ltd Shenzhen Branch, adhering to ANSI/IEEE Std 149-2021 standards. The testing period spanned from March 3, 2025, to March 12, 2025, with the report issued on May 15, 2025.
The report outlines the testing environment, equipment used, and measurement uncertainties. Key results include efficiency and gain measurements across the 2400-2500 MHz frequency range, presented for three different free space configurations. The report also features pattern plots, including return loss, VSWR, and stimulus plots, as well as 2-D and 3-D antenna patterns. The document concludes with a detailed view of the EUT and the test setup.
The purpose of this report is to provide a comprehensive assessment of the antenna's passive performance characteristics, ensuring compliance with specified standards and providing valuable insights for product development and optimization.
