The RF output of the equipment under test was directly connected to the input of the spectrum analyzer applying suitable attenuation. The Resolution Bandwidth (RBW) of the spectrum analyzer was set to 100 kHz. The Video Bandwidth (VBW) was set to ≥ 300 kHz. The resulting spectrum analyzer peak level was used to determine the reference level with respect to the 30 dBc limit at the band edges. The spectrum span was then adjusted for the measurement of spurious emissions from 30MHz to 25GHz, 10 times the highest fundamental frequency. The worst-case for each modulation was investigated at the lower and upper band edges. For the 30MHz to 25GHz measurements, only the worst-case with respect to power was investigated: 802.11b, 11Mbps. 7.5.1.2 Measurement Results Performed by: Jeremy Pickens Figure 7.5.1.2-1: 802.11b – LCH – 30MHz–25GHz Figure 7.5.1.2-2: 802.11b – MCH – 30MHz–25GHz Report: AT72139651-1C0 Page 17

Model(s): ACT2 FCC ID: SK9ACT2 IC: 864G-ACT2 7.5.2 Emissions into Restricted Frequency Bands – FCC: 15.205, 15.209; ISED Canada: RSS-Gen 8.9 / 8.10 7.5.2.1 Measurement Procedure The unwanted emissions into restricted bands were measured radiated over the frequency range of 30MHz to 25GHz, 10 times the highest fundamental frequency. The EUT was rotated through 360° and the receive antenna height was varied from 1 meter to 4 meters so that the maximum radiated emissions level would be detected. For frequencies below 1000 MHz, quasi-peak measurements were made using a resolution bandwidth RBW of 120 kHz and a video bandwidth VBW of 300 kHz. For frequencies above 1000 MHz, peak and average measurements were made with RBW and VBW of 1 MHz and 3 MHz respectively. Each emission found to be in a restricted band as defined by section 15.205, including any emission at the operational band-edge, was compared to the radiated emission limits as defined in section 15.209. 7.5.2.2 Measurement Results Performed by: Jeremy Pickens Radiated spurious emissions found in the band of 30MHz to 25GHz are reported in the Tables 7.5.2.2-1 to 7.5.2.2-4 below.
