Model: L+G Focus AX w/ Zigbee Utilinet Endpoint FCC ID: R7PER1R2S4 7.5.3 Channel Dwell Time The maximum duration of the RF transmission is 364ms during a 700ms channel dwell time. There is a minimum of 50 channels used during the hopping sequence therefore a channel will not be re-occupied until at least 35s. Therefore the average time of occupancy on any one channel in a 20 second period is 364ms. A detailed description of the channel dwell time is included in the Theory of Operation. 7.5.4 20dB Bandwidth 7.5.4.1 Test Methodology The spectrum analyzer span was set to 2 to 3 times the estimated 20 dB bandwidth of the emission. The RBW was to ≥ 1% of the estimated 20 dB bandwidth. The trace was set to max hold with a peak detector active. The Delta function of the analyzer was utilized to determine the 20 dB bandwidth of the emission. The span and RBW were examined and re-adjusted if necessary to meet the requirements of 2 to 3 times the 20 bandwidth for the span and ≥ 1% of the 20 dB bandwidth for the RBW. 7.5.4.2 Test Results The maximum 20dB bandwidth was found to be approximately 28.50kHz.

Model: L+G Focus AX w/ Zigbee Utilinet Endpoint FCC ID: R7PER1R2S4 7.6.3 Radiated Spurious Emissions (Restricted Bands) - FCC Section 15.205 7.6.3.1 Test Methodology Radiated emissions tests were made over the frequency range of 30MHz to 10GHz, 10 times the highest fundamental frequency. The EUT was rotated through 360° and the receive antenna height was varied from 1m to 4m so that the maximum radiated emissions level would be detected. For frequencies below 1000MHz, quasi-peak measurements were made using a resolution bandwidth (RBW) of 120 kHz and a video bandwidth (VBW) of 300 kHz. For frequencies above 1000MHz, average measurements were made using an RBW of 1 MHz and a VBW of 10 Hz and peak measurements were made with RBW of 1 MHz and a VBW of 1 MHz. The EUT was caused to generate a continuous carrier signal on the hopping channel. 7.6.3.2 Test Results Radiated spurious emissions found in the band of 30MHz to 10GHz are reported in Tables 7.6.3-1. through 7.6.3-3. Each emission found to be in a restricted band as defined by section 15.205, was compared to the radiated emission limits as defined in section 15.209.
