For smart system, Maximum Conducted Output Power is defined as the total transmit power delivered to all antennas and antenna elements averaged across all symbols in the signaling alphabet when the transmitter is operating at its maximum power control level. Power must be summed across all antennas and antenna elements. If multiple modes of operation are possible (e.g., alternative modulation methods), the maximum conducted output power is the highest total transmit power occurring in any mode. Set the RBW DTS bandwidth(about 1MHz). Set VBW =3*RBW(about 3MHz) Set the span 3*RBW Set Sweep time = auto couple. Set Detector = peak. Set Trace mode = max hold. Allow trace to fully stabilize. Use peak marker function to determine the peak amplitude level. According to FCC Part 15.247(b)(4): 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. 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)(3) of this section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi. 8.2.5 Test Results Temperature: Relative Humidity: ATM Pressure: Test Engineer: 25 C 45 1011 mbar XXH TestMode BLE_1M BLE_2M Antenna Ant1 Ant1 Freq(MHz) 2402 2440 2480 2402 2440 2480 Conducted Peak Powert[dBm] 6.68 7.07 7.21 6.73 7.17 7.41 Conducted Limit[dBm] 30 30 30 30 30 30 EIRP[dBm] 8.48 8.87 9.01 8.53 8.97 9.21 EIRP Limit[dBm] 36 36 36 36 36 36 Verdict PASS PASS PASS PASS PASS PASS Report No. ENS2408200268W00101R Page 18 of 53 Ver.1.0 BLE_1M_Ant1_2402 BLE_1M_Ant1_2440 Report No. ENS2408200268W00101R BLE_1M_Ant1_2480 Page 19 of 53 Ver.1.0 BLE_2M_Ant1_2402 BLE_2M_Ant1_2440 Report No. ENS2408200268W00101R BLE_2M_Ant1_2480 Page 20 of 53 Ver.1.0 8.3 MAXIMUM POWER SPECTRAL DENSITY 8.3.1 Applicable Standard According to FCC Part 15.247(e) and KDB 558074 D01 15.247 Meas Guidance v05r02 8.3.2 Conformance Limit The transmitter power spectral density conducted from the transmitter to the antenna shall not be greater than 8 dBm in any 3 kHz band during any time interval of continuous transmission. 8.3.3 Test Configuration Test according to clause 7.1 radio frequency test setup 1 8.3.4 Test Procedure This procedure shall be used if maximum peak conducted output power was used to demonstrate compliance The transmitter output (antenna port) was connected to the spectrum analyzer Set analyzer center frequency to DTS channel center frequency.

It must be performed with the highest gain of each type of antenna proposed for use with the EUT. Use the following spectrum analyzer settings: The EUT was placed on a turn table which is 0.8m above ground plane. Maximum procedure was performed on the highest emissions to ensure EUT compliance. Span = wide enough to fully capture the emission being measured RBW = 1 MHz for f 1 GHz(1GHz to 25GHz), 100 kHz for f < 1 GHz(30MHz to 1GHz) VBW RBW Sweep = auto Detector function = peak Trace = max hold Report No. ENS2408200268W00101R Page 36 of 53 Ver.1.0 Follow the guidelines in ANSI C63.10-2013 with respect to maximizing the emission by rotating the EUT, measuring the emission while the EUT is situated in three orthogonal planes (if appropriate), adjusting the measurement antenna height and polarization, etc. A pre-amp and a high pass filter are required for this test, in order to provide the measuring system with sufficient sensitivity. Allow the trace to stabilize. The peak reading of the emission, after being corrected by the antenna factor, cable loss, pre-amp gain, etc., is the peak field strength, which must comply with the limit specified in Section 15.35(b). Submit this data. Now set the VBW to 10 Hz, while maintaining all of the other instrument settings. This peak level, once corrected, must comply with the limit specified in Section 15.209. If the dwell time per channel of the hopping signal is less than 100 ms, then the reading obtained with the 10 Hz VBW may be further adjusted by a "duty cycle correction factor", derived from 20log(dwell time/100 ms), in an effort to demonstrate compliance with the 15.209 limit. Submit this data. Repeat above procedures until all frequency measured was complete. 8.5.5 Test Results Pass Temperature: Relative Humidity: ATM Pressure: Test Engineer: Test Date 20.8 °C 61 1011 mbar CZF 2024/5/14 Spurious Emission below 30MHz (9KHz to 30MHz) Freq.

The lower limit shall apply at the transition frequencies 2. The limit decreases in line with the logarithm of the frequency in the range of 0.15 to 0.50MHz. 8.6.3 Test Configuration Test according to clause 7.3 conducted emission test setup 8.6.4 Test Procedure The EUT was placed on a table which is 0.8m above ground plane. Maximum procedure was performed on the highest emissions to ensure EUT compliance. Repeat above procedures until all frequency measured were complete. 8.6.5 Test Results Not Applicable Report No. ENS2408200268W00101R Page 49 of 53 Ver.1.0 8.7 ANTENNA APPLICATION 8.7.1 Antenna Requirement Standard FCC CRF Part 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 shall be considered sufficient to comply with the provisions of this section. 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. This requirement does not apply to carrier current devices or to devices operated under the provisions of §15.211, §15.213, §15.217, §15.219, or §15.221. Further, this requirement does not apply to intentional radiators that must be professionally installed, such as perimeter protection systems and some field disturbance sensors, or to other intentional radiators which, in accordance with §15.31(d), must be measured at the installation site. However, the installer shall be responsible for ensuring that the proper antenna is employed so that the limits in this part are not exceeded. For intentional device, according to FCC 47 CFR Section 15.203, 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. And according to FCC 47 CFR Section 15.247 (b), if transmitting antennas of directional gain greater than 6dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi. 8.7.2 Result PASS Antenna use a permanently attached antenna which is not replaceable. Not using a standard antenna jack or electrical connector for antenna replacement The antenna has to be professionally installed (please provide method of installation) Note: Please refer to the attached document Internal Photos to show the antenna connector.
