Limit All restriction band should comply with 15.209, other emission should be at least 20dB below the fundamental. 10.3. Test procedure (1) Connect EUT’s antenna output to spectrum analyzer by RF cable. (2) Establish a reference level by using the following procedure: RBW:100 kHz VBW:300 kHz SpanEncompass frequency range to be measured Detector Mode:Peak Sweep time:Auto Trace modeMax hold (3) Allow the trace to stabilize, use the peak marker function to determine the maximum peak power level to establish the reference level. (4) Then mark the maximum amplitude of all unwanted emissions outside of the authorized frequency band.Appendix G: Band edge measurements Guangdong Dongdian Testing Service Co., Ltd.
