FCC ID: HSW-2410G 2.10 Band Edge Measurements Band Edge measurements were made at a Low Channel and High Channel peak at highest EUT related emission outside the occupied bandwidth. A peak measurement was made of the fundamental, and the emission was measured using a peak setting. A Resolution Bandwidth of > 1% of the emission bandwidth was used. This procedure was repeated for the high channel. The plots shown were verified to be from the worst case antenna used (Parabolic Dish), using a 17 foot, Flexco cable and Horn Antenna. No preamp was used. The limits were derived as follows: High Bandedge 5000 uV/m = -32.02 dBm -33.02 dBm – 31.88 dB (antenna factor and cable loss) = -64.9 dBm -64.9 dBm + 9.54* dB = -55.36 dBm limit Low Bandedge -33.02 dBm – 32.03 dB (antenna factor and cable loss) = 65.05 dBm -65.05 dBm + 9.54* dB = -55.51 dBm limit * -9.54 dB correction from 3m to 1m distance. 188
