2. Start test system transmitting beacons in slots 2–10 with nominal intervals of
65538 microseconds (as reported by the analyzer). Each beacon is sent a random
number of microseconds from 0 to 4 earlier than the scheduled location based on
the nominal interval. The BP Length is set to 21. The EUI-48 in all the test system
beacons is set to NULL and the DevAddr is set to 2.
3. Standard test start-up sequence.
4. After 1 minute, test system stops beaconing.
5. After at least 2 seconds, stop the analyzer capture.
Notes:
• Background observation checks verify DUT & INTD follow correct signaling and
slot contraction behavior.
Test Case 3.5: Slowly Drifting Alien BP Requires Repeated BPST Realignment
This test verifies that DUT/INTD adjust to the changing BPST or to cease operation
and/or beaconing once synchronization has been lost. The DUT/INTD are also allowed
to stop if adjusting to the "new" BPST would put place them in a slot higher than 20.
The Tester runs “fast “. The DUT/INTD generally become unsynchronized with the
Tester very quickly.
Test procedure:
1. Start analyzer capture.
2. Test system starts the beacon period and sends a beacon in slot 2 with
calibrated intervals of 65538 microseconds. The BP Length is set to 12.
3. Standard test start-up sequence.
4. The test system changes its beacon period interval to 65533 microseconds.
5. After two minutes, the test system stops beaconing.
6. Once the DUT and INTD are beaconing in slots 2 and 3 or at least 10 seconds
have elapsed (whichever occurs first), stop analyzer capture.
Notes:
The normal background checks are not valid for this test case. Manual review of
captured trace is performed for the following:
• The BPST of the DUT and INTD must be no greater that 12 usec earlier or 85
usec later than the test system’s BPST.
