Therefore, there may be 0.1 difference for the result. *1) The test is not applicable since the EUT does not have AC Mains. *These tests were performed without any deviations from test procedure except for additions or exclusions. 3.3 Uncertainty Radiated Emission The measurement uncertainty (with a 95% confidence level) for this test using Biconical antenna is ±4.5dB(3m). The measurement uncertainty (with a 95% confidence level) for this test using Logperiodic antenna is ±5.2dB(3m). The measurement uncertainty (with a 95% confidence level) for this test using Horn antenna is ±6.6dB(3m). The data listed in this report meets the limits unless the uncertainty is taken into consideration. 3.4 Test Location UL Apex Co., Ltd.
