Radiated Emission Measurements The measurement is made according to ANSI C63.10 The radiated emission test is performed in semi-anechoic chamber. The EUT was placed on a non-conductive table with 80cm above the ground plane for measurement below 1GHz and 1.5m above the ground plane for measurement above 1GHz. The measurement antenna was placed at a distance of 3 meters from the EUT. The test is carried out on both vertical and horizontal polarization and only maximization result of both polarizations is kept. During the test, the turntable is rotated from 0° to 360°and the measurement antenna is moved from 1m to 4m to get the maximization result. The maximization process was repeated with the EUT positioned in each of its three orthogonal orientations ©Copyright. All rights reserved by CTTL. Page 13 of 73 No.25T04Z100116-005 A.2. Maximum Output Power Method of Measurement: See ANSI C63.10-2013-clause 11.9.1.3 The maximum peak conducted output power may be measured using a broadband peak RF power meter.

Transmitter Spurious Emission A.6.1 Transmitter Spurious Emission Conducted Method of Measurement: See ANSI C63.10-2013-clause 11.11 Establish a reference level by using the following procedure: a) Set instrument center frequency to DTS channel center frequency b) Set the span to 1.5 times the DTS bandwidth c) Set the RBW= 100 kHz d) Set the VBW= 300 kHz e) Detector = Peak f) Sweep time = auto couple g) Trace mode = max hold h) Allow trace to fully stabilize i) Use the peak marker function to determine the maximum PSD level Note that the channel found to contain the maximum PSD level can be used to establish the reference level. Establish an emission level by using the following procedure: a) Set the center frequency and span to encompass frequency range to be measured. b) Set the RBW = 100 kHz. c) Set the VBW = 300 kHz. d) Detector = peak. e) Sweep time = auto couple. f) Trace mode = max hold. g) Allow trace to fully stabilize. h) Use the peak marker function to determine the maximum amplitude level. Ensure that the amplitude of all unwanted emissions outside of the authorized frequency band (excluding restricted frequency bands) is attenuated by at least the minimum requirements specified in 11.11. Report the three highest emissions relative to the limit.
