Model(s): CAT1 FCC ID: SK9CAT1 IC: 864G-CAT1 1.3 Test Methodology and Considerations All modes of operation, including all data rates, were evaluated and the data presented in this report represents the worst case where applicable. The worst-case data rate for 802.11b mode was 1Mbps. The worst-case data rate for 802.11g mode was 6Mbps. The worst-case data rate for 802.11n (HT 20) mode was MCS0. The worst-case data rate for 802.11n (HT 40) mode was MCS0. For radiated emissions, the EUT was evaluated in three orthogonal orientations. The worst-case orientation was Y-position. See test setup photos for more information. For AC power line conducted emissions the EUT was directly connected to the AC mains using the wiring that would normally be connected to the meter. For RF Conducted measurements, the EUT was connected to the test equipment with an MMX to SMA adapter. The EUT was programmed to generate a continuously modulated signal on each channel evaluated. Radiated inter-modulation testing was performed for all combinations of simultaneous transmission and found to be compliant.

The Resolution Bandwidth (RBW) of the spectrum analyzer was set to 100 kHz. The Video Bandwidth (VBW) was set to ≥ 3 times the RBW. The trace was set to max hold with a peak detector active. The marker-delta function of the spectrum analyzer was utilized to determine the 6 dB bandwidth of the emission. The occupied bandwidth measurement function of the spectrum analyzer was used to measure the 99% bandwidth. The span of the analyzer was set to capture all products of the modulation process, including the emission sidebands. The resolution bandwidth was set from 1% to 5% of the occupied bandwidth and the video bandwidth set to at least 3 times the resolution bandwidth. A peak detector was used. 7.3.2 Measurement Results Performed by: Jeremy Pickens Table 7.3.2-1: 6dB / 99% Bandwidth Frequency 6dB Bandwidth 99% Bandwidth Modulation (MHz) (MHz) (MHz) 2412 10.10 14.60 802.11b 2437 10.15 14.70 2462 10.15 14.60 2412 15.20 16.40 802.11g 2437 15.20 19.10 2462 15.40 16.40 2412 15.20 17.60 802.11n(HT20) 2437 15.15 19.10 2462 15.15 17.60 2422 33.85 33.75 802.11n(HT40) 2437 33.90 36.75 2452 33.90 36.00 Report: AT72151409-1C1 Page 12

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.

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.
