Conducted Measurements The measurement is made according to ANSI C63.10. 1). Connect the EUT to the test system correctly. 2). Set the EUT to the required work mode (Transmitter, receiver or transmitter & receiver). 3). Set the EUT to the required channel. 4). Set the EUT hopping mode (hopping or hopping off). 5). Set the spectrum analyzer to start measurement. 6). Record the values. Vector Signal Analyzer EUT Vector Signal Analyzer B.1.2. 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 15 of 44. B.2.

AC Powerline Conducted Emission Summary All AC line conducted spurious emissions are measured with a receiver connected to a grounded LISN while the EUT is operating at its maximum duty cycle, at maximum power, and at the appropriate frequencies. All data rates and modes were investigated for conducted spurious emissions. Only the conducted emissions of the configuration that produced the worst case emissions are reported in this section Method of Measurement: See Clause 6.2 of ANSI C63.10 specifically. See Clause 4 and Clause 5 of ANSI C63.10 generally. The conducted emissions from the AC port of the EUT are measured in a shielding room. The EUT is connected to a Line Impedance Stabilization Network (LISN). An overview sweep with peak detection was performed. The measurements were performed with a quasi-peak detector and if required, an average detector. The conducted emission measurements were made with the following detector of the test receiver:Quasi-Peak / Average Detector. The measurement bandwidth is: Frequency of Emission (MHz) RBW/IF bandwidth 0.15-30 9kHz Test Condition: VoltageV 120 FrequencyHz 60 Test setup ©Copyright. All rights reserved by CTTL. Page 39 of 44.
