Report No: CCISE190608401 6 Test results and Measurement Data 6.1 Antenna requirement: Standard requirement: FCC Part 15 C Section 15.203 /247(b) 15.203 requirement: An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator, the manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. 15.247(b) (4) requirement: (4) The conducted output power limit specified in paragraph (b) of this section is based on the use of antennas with directional gains that do not exceed 6 dBi. Except as shown in paragraph (c) of this section, if transmitting antennas of directional gain greater than 6 dBi are used, the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs (b)(1), (b)(2), and (b)(3) of this section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi. E.U.T Antenna: The BLE antenna is an Internal antenna which cannot replace by end-user, the best-case gain of the antenna is 0.59 dBi. Shenzhen Zhongjian Nanfang Testing Co., Ltd.

Report No: CCISE190608401 6.2 Conducted Emission Test Requirement: FCC Part 15 C Section 15.207 Test Frequency Range: 150 kHz to 30 MHz Class / Severity: Class B Class B Receiver setup: RBW=9kHz, VBW=30kHz Limit: Limit (dBuV) Frequency range (MHz) Quasi-peak Average 0.15-0.5 66 to 56* 56 to 46* 0.5-5 56 46 5-30 60 50 * Decreases with the logarithm of the frequency. Test procedure 1. The E.U.T and simulators are connected to the main power through a line impedance stabilization network (L.I.S.N.), which provides a 50ohm/50uH coupling impedance for the measuring equipment. 2. The peripheral devices are also connected to the main power through a LISN that provides a 50ohm/50uH coupling impedance with 50ohm termination. (Please refer to the block diagram of the test setup and photographs). 3. 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.

Report No: CCISE190608401 6.6.2 Radiated Emission Method Test Requirement: FCC Part 15 C Section 15.205 and 15.209 Test Frequency Range: 2.3GHz to 2.5GHz Test Distance: 3m Receiver setup: Frequency Detector RBW VBW Remark Peak 1MHz 3MHz Peak Value Above 1GHz RMS 1MHz 3MHz Average Value Limit: Frequency Limit (dBuV/m @3m) Remark 54.00 Average Value Above 1GHz 74.00 Peak Value Test Procedure: 1. The EUT was placed on the top of a rotating table 1.5 meters above the ground at a 3 meter camber. The table was rotated 360 degrees to determine the position of the highest radiation. 2. The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top of a variable-height antenna tower. 3. The antenna height is varied from one meter to four meters above the ground to determine the maximum value of the field strength. Both horizontal and vertical polarizations of the antenna are set to make the measurement. 4. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights from 1 meter to 4 meters and the rota table was turned from 0 degrees to 360 degrees to find the maximum reading. 5. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold Mode. 6. If the emission level of the EUT in peak mode was 10 dB lower than the limit specified, then testing could be stopped and the peak values of the EUT would be reported. Otherwise the emissions that did not have 10 dB margin would be re-tested one by one using peak, quasi- peak or average method as specified and then reported in a data sheet.
