Step 6:
• Make the following changes on the analyzer:
- Start Frequency: 2 400 MHz
- Stop Frequency: 2 483,5 MHz
- RBW: ~ 50 % of the Occupied Channel Bandwidth (single hop)
- VBW:
RBW
- Detector Mode: RMS
- Sweep time: Auto
- Trace Mode: Max Hold
- Trigger: Free Run
• When the trace has completed, indentify the number of hopping frequencies used by the hopping sequence.
• The result shall be compared to the limit (value N) defined in clauses 4.3.1.3.2.1 or 4.3.1.3.2.2. This value
shall be recorded in the test report.
For equipment with blacklisted frequencies, it might not be possible to verify the number of hopping
frequencies in use. However they shall comply with the requirement for accumulated Dwell time and
Minimum Frequency Occupation Time assuming the minimum number of hopping frequencies defined in
clauses 4.3.1.3.2.1 or 4.3.1.3.2.2 are in use.
Step 7:
• For adaptive systems, using the lowest and highest -20 dB points from the total spectrum envelope obtained in
step 6, it shall be verified whether the system uses 70 % of the band specified in clause 1. The result shall be
recorded in the test report.
5.3.4.2.2 Radiated measurements
This method shall only be used for integral antenna equipment that does not have a temporary antenna connector(s)
provided.
A test site as described in annex B and applicable measurement procedures as described in annex C may be used.
Alternatively, a test fixture may be used.
The test procedure is further as described under clause 5.3.4.2.1.
5.3.5 Hopping Frequency Separation
5.3.5.1 Test conditions
See clause 5.1 for the test conditions. These measurements shall only be performed at normal test conditions.
The measurement shall be performed on 2 adjacent hopping frequencies. The frequencies on which the test was
performed shall be recorded.
