04)

• If more than one antenna assembly is intended for this power setting, the maximum overall antenna gain (G or

G + Y) shall be used.

• The RF Output Power (P) shall be calculated using the formula below:

P = A + G + Y

• This value, which shall comply with the limit given in clauses 4.3.1.1.2 or 4.3.2.1.2, shall be recorded in the

test report.

5.3.2.2.1.2 Duty Cycle, Tx-sequence, Tx-gap

The test procedure, which shall only be performed for non-adaptive systems, shall be as follows:

Step 1:

• Use the same stored measurement samples from the procedure described in clause 5.3.2.2.1.1.

Step 2:

• Between the saved start and stop times of each individual burst, calculate the TxOn time. Save these TxOn

values.

• Between the saved stop and start times of two subsequent bursts, calculate the TxOff time. Save these TxOff

values.

Step 3:

• Duty Cycle is the sum of all TxOn times divided by the observation period defined in clauses 4.3.1.2.1 or

4.3.2.3.1.

• For equipment using blacklisting, the TxOn time measured for a single (and active) hopping frequency shall be

multiplied by the number of blacklisted frequencies. This value shall be added to the sum calculated in the

previous bullet point. If the number of blacklisted frequencies cannot be determined, the minimum number of

hopping frequencies as defined in clause 4.3.1.3.2 shall be assumed.

• The above calculated value for Duty Cycle shall be recorded in the test report. This value shall be equal to or

less than the maximum value declared by the supplier.

Step 4:

• Any TxOff time that is greater than the minimum Tx-gap time is considered a Tx-gap. The lowest Tx-gap time

shall be recorded in the test report. The minimum Tx-gap time is defined in clauses 4.3.1.2.2 or 4.3.2.3.2.

• The Tx-sequence time is the time between two subsequent Tx-gaps. The maximum Tx-sequence time shall be

recorded in the test report. Any Tx-sequence shall be shorter than the value defined in clauses 4.3.1.2.2 or

4.3.2.3.2.

5.3.2.2.1.3 Medium Utilisation

The test procedure, which shall only be performed for non-adaptive systems, shall be as follows:

Step 1:

• Use the same stored measurement samples from the procedure described in clause 5.3.2.2.1.1.

Step 2:

• For each burst calculate the product of (P

burst

/100 mW) and the TxOn time.

NOTE: P

burst

is expressed in mW. TxOn time is expressed in ms.
