Turbo-Mode Band Edge Measurements (Revised) The attached data represents revised measurement data for the Atheros application under FCC ID PPD-AR5BCB-00012. The data originally submitted for the band edge measurement data is incorrect as it used the field strength data for the normal mode fundamental signals and not the fundamental field strength data for the turbo mode This data should be used to replace pages 21 – 23 of the pdf file Atheros Radio Report Test log.PDF.

Date of Test: 10/12/2001 Config. Used: Test Engineer: Jmartinez Config Change: Test Location: SVOATS# 4 Host Unit Voltage 120Vac, 60Hz General Test Configuration The EUT was located on the turntable for radiated spurious emissions testing. For radiated emissions testing the measurement antenna was located 3 meters from the EUT unless stated otherwise. When measuring the conducted emissions from the EUT's antenna port, the antenna port of the EUT was connected to the spectrum analyzer or power meter via a suitable attenuator to prevent overloading the measurement system. All measurements are corrected to allow for the external attenuators and cables used. Ambient Conditions: Temperature: 24°C Rel. Humidity: 80% Summary of Results Run # Test Performed Limit Result Comments RE, 1000 - 40000 MHz - 1 15.407(b)(6) Pass -3.62dB @ 5350 MHz Spurious Emissions Modifications Made During Testing: No modifications were made to the EUT during testing Deviations From The Standard No deviations were made from the requirements of the standard.
