Significant peaks are then marked and then Quasi Peak detector mode re—measured. e. If the Peak Mode measured value compliance with and lower than Quasi Peak Mode Limit, the EUT shall be deemed to meet QP Limits and then no additional QP Mode measurement performed. f.

Report No.: BGTC—FY 190805287E 4. 100 KHZ BANDWIDTH OF FREQUENCY BAND EDGE APPLIC ABLE STAND ARD Emissions radiated outside of the specified frequency bands, except for harmonics, shall be attenuated by at least 50 dB below the level of the fundamental or to the general radiated emission limits in § 15.209, whichever is the lesser attenuation TEST PROCEDURE a) Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. b) Position the EUT without connection to measurement instrument. Turn on the EUT and connect its antenna terminal to measurement instrument via a low loss cable. Then set it to any one measured frequency within its operating range, and make sure the instrument is operated in its linear range. C) i) VBW for Peak, Quasi—peak, or Average Detector Function: 3 x RBW d) Repeat above procedures until all measured frequencies were complete. Note: Both horizontal and vertical antenna polarities were tested and performed pretest to three orthogonal axis. The worst case emissions were reported 4.1 DEVIATION FROM STANDARD No deviation. 4.2 TEST SETUP 4.3 EUT OPERATION CONDITIONS The EUT tested system was configured as the statements of 2.4 Unless otherwise a special operating condition is specified in the follows during the testing. 4.4 TEST RESULTS Test Report Tel: 400—788—9558— Web: https:/www.bcitc—lab.com BCTC/RF—EMC—007 Ver: A0 Page 23 of 30
