The values reported are the maximum values.1.6 Configuration of the EUTThe EUT was configured according to CISPR16. All interface ports were connected to the appropriate peripherals. All peripherals and cables are listed below.A.EUTB.PeripheralsC.EUT ExerciseThe EUT (Transmitter) was operated in the engineering mode to fix the Tx frequency that was for the purpose of the measurements.1.7 EUT ModificationsNo modification by Shenzhen TCT Testing Technology Co., Ltd1.8 Measurement Uncertainty（95% confidence levels, k=2)2. Technical Test2.1Summary of Test Results2.2 Test ReportTest Report ReferenceNote: The clause numbers are referenced to ETSI EN 300 328 V 1.7.1(2006-10)Clause 4.3.1 Effective Isotropic Radiated Power (Conducted)Remarks:A temporary antenna connector provided when this test item was done. And the EUT was connected to the power meter through the connector.EIRP is calculated by method described under sub clause 7.2.1.2, using following formulae;P=A+G+10 log (1/x);Where:A=Average Power (measured)G= Antenna Gain= 2.5dBix= Duty Cycle=0.337 (measured)Av: Average Power During BurstClause 4.3.3 Frequency RangeClause 4.3.4 Frequency hopping requirementsThe Frequency Hopping systems used by the EUT is the type of Adaptive Frequency Hopping systemsActual = Reading × (Hopping rate / Number of channels) × Test period Test period = 0.4 [seconds / channel] × 79 [channel] = 31.6 [seconds] NOTE: The EUT makes worst case 1600 hops per second or 1 time slot has a length of 625µs with 79 channels. A DH5 Packet needs 5 time slot for transmitting and 1 time slot for receiving. Then the EUT makes worst case 266.667 hops per second with 79 channels. It also meet the requirement of clause 4.3.4.3. Each hopping channel of the hopping sequence is occupied at least once during a period not exceeding four times the product of the dwell time per hop and the number of channels.Test Plots:Low Channel: DH5 (Under test mode)Middle Channel: DH5 (Under test mode)High Channel：DH5 (Under test mode)Low Channel: DH3(Under test Mode)Middle Channel: DH3(Under test Mode)High Channel: DH3 (Under test mode)Low Channel: DH1 (Under test mode)Middle Channel: DH1 (Under test mode)High Channel: DH1: (Under test mode)4.3.4.2 Hopping channelEUT scissors feet ABS bluetoothkeyboardModel HB023A Mode Keep Transmitting Input Voltage DC 3.7V Temperature 26 deg.

Measurements were conducted on low & high channels, but the worst case was submitted in the report only.2. The receiver spurious emissions were conducted with different settings, using the relevant pre-amplifiers for the relevant frequency ranges.NF=No significant peak noise was found3.0 Product LabellingCE Mark label specificationText of the mark is black or white in color and is left justified.
