Test Case 3.2: BPST Adjustment Limit
This test case verifies that the DUT & INTD do not adjust more than ±12us from the nominal
slot boundary as the Test system beacon drifts out of sync.
Test procedure:
1.
Start analyzer capture.
2. Test system starts the beacon period and sends a beacon in slot 2. The BP
Length is set to 12.
3. Standard test start-up sequence.
4. The test system starts transmitting its beacons with an interval of 65544
microseconds.
5. After 2 seconds, test system stops beaconing.
6. After DUT and INTD are beaconing in slots 2 and 3 or at least 10 seconds
(whichever occurs first), stop analyzer capture.
Notes:
• The DUT fails if it is not transmitting beacons at least 12 microseconds faster
than the test system beacons at any point within 20 superframes of the test
system beacon interval increase.
• The DUT and INTD are allowed to cease demonstrating operation and/or beacon
transmission during this test case once synchronization with the test system has
been lost. Beacon transmission must automatically restart without manual
intervention if it ceases.
