Test Case 1.3: TD.8.2.3.4 Beacon Period Length Extension By Test System
This test verifies that the DUT correctly extends its BP length and properly operates after
beacons are placed in upper slots. After a normal startup the tester starts sending additional
beacons in signaling slot and slot 15 requiring the DUT & INTD to extend their BP length. The
Tester then sends a beacon in a signaling slot with slot number 25. After 2 seconds, the test
system stops sending the beacons in slots 15 and 25. The DUT and INTD should extend and
then shorten their BP length appropriately while remaining in their current beacon slot.
In the UWBTracer Beacon Period Viewer, the height of the Columns represents the advertised BP length. The test system stops
transmitting in SF 622 but the test beacon is still reported in slot 25 in prior superframe; At this point, the devices must wait until the next
superframe to consider the slot 25 “unoccupied”. After waiting 4 more superframes, the devices correctly reduce their bp length in
superframe 627.
Test procedure
1. Start analyzer capture.
2. Test system starts the beacon period and sends a beacon in slot 2 with a BP
Length of 12.
3. Standard test start-up sequence. After 1 second, stop analyzer capture.
4. After 1 second, test system stops beaconing.
5. After at least 2 seconds, stop analyzer capture.
