The E.U.T and simulators are connected to the main power through a line impedance stabilization network (L.L.S.N.}. This provides a 50ohm/50uH coupling impedance for the measuring equipment. . The peripheral devices are also connected to the main power through a LISN that provides a 50ohm/50uH coupling impedance with 50o0hm termination. (Please Test Procedure: refer to the block diagram of the test setup and photographs). .Both sides of A.C. line are checked for maximum conducted interference. In order to find the maximum emission, the relative positions of equipment and all of the interface cables must be changed according to ANSI C63.10:2013 on conducted measurement.

Data of measurement shown “---“in the above table mean that the reading of emissions is attenuated more than 20 dB below the limits or the field strength is too small to be measured.

Report No.: TCT180529E015 6.4. 20dB Occupied Bandwidth 6.4.1. Test Specification FCC Part15 C Section 15.215(c)/ Part 2 J Section Test Requirement: 2.1049 Test Method: ANSI C63.10: 2013 Limit: N/A 1. According to the follow Test-setup, keep the relative position between the artificial antenna and the EUT. 2. Set to the maximum power setting and enable the EUT transmit continuously. 3. Use the following spectrum analyzer settings for 20dB Bandwidth measurement. Span = approximately 2 to 3 times the 20 dB bandwidth, centered on a hopping channel; RBW≥1% of the 20 dB bandwidth; VBW≥RBW; Sweep = auto; Detector function = peak; Trace = max hold. 4. Measure and record the results in the test report. Test setup: Test Mode: Transmitting mode with modulation Test results: PASS 6.4.2.
