Ubiquiti Networks AP-1 FCC Compliance Data TESTING SETUP OVERVIEW INSTRUMENTS USED Description Manufacturer Model No. Last Calibration Spectrum Analyzer Rhode & Schwarz ESIB 26 Nov, 2004 The AP-1 was placed in continuous transmit mode using the Atheros Radio Test (ART) software utility. Data was captured from the spectrum analyzer using a PC, a National Instruments GPIB/ENET hub, and a National Instruments Labview customized program. TEST DATE: January 14, 2004 6 dB Bandwidth 15.247(a) Requirement: For direct sequence systems, the minimum 6dB bandwidth shall be at least 500 kHz. Test Setup: The antenna output is connected into the spectrum analyzer. RBW and VBW are each set to 100 kHz. The frequency is centered at the carrier center frequency with a 25 MHz span.
