Note: 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= 2.5dBi
x= Duty Cycle=0.337 (measured)
Av: Average Power During Burst
Clause 4.3.3 Frequency Range
Clause 4.3.4 Frequency hopping requirements
The Frequency Hopping systems used by the EUT is the type of Adaptive Frequency Hopping systems
Actual = 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.
