SELF TEST ERRORS
The Tests will halt if a Self Test Error is detected. A message indicating the test
point being run and error detected is displayed. Check all loopback connections and
re-run the test. If the problem persists and contact your local HP Service Office or
representative. Tests should only performed in a stable ambient environment where
the instrument will not be disturbed during test.
The Self Test Error code numbering uses the following numeric format.
First Number indicates the Test being run.
CPU
1xxx
CONFIDENCE. 2xxx
PDH
3xxx (for Subtests < 100), 18xxx (for Subtests 100+)
BER
4xxx
JITTER
5xxx (for Subtests<100, 20xxx (for Subtests 100+)
LONG GATING 6xxx
Note ALL TESTS uses the number from the tests it calls.
The next digits indicate the Subtest, e.g. 415x, is Subtest 15 of Test 4 (BER).
(where subtests are >99 the numbering restarts)
The last digit indicates the error type. In general these are -
1 = Loss of Signal
2 = specific for subtest
3 = test result too low
4 = test result too high
5 = loss of frame sync
6 = loss of pointer sync
7 = loss of pattern sync
The error codes are accompanied by appropriate error messages.
