238
FTB-860/880
Summary Results
Start Time

Start Time : The time when the CPRI/OBSAI test was started.
Interface

LOS (Loss Of Signal): LOS is declared when there is no input signal.

Symbol Error
: A Symbol Error is declared when invalid symbols are
detected.
BER

Pattern Loss : Pattern Loss is declared when the bit error ratio is
greater than or equal to 0.20 during an integration interval of 1 second,
or it can be unambiguously identified that the test sequence and the
reference sequence are out of phase.

Bit Error : Bit Error is declared when there are logic errors in the bit
stream (i.e., zeros that should be ones and vice versa).

Mismatch ‘0’ : A mismatch “0” error indicates a bit error on a binary “0”
(i.e.ones that should be zeros) found in the receiving test pattern only.

Mismatch ‘1’ : A mismatch “1” error indicates a bit error on a binary “1”
(i.e. zeros that should be ones) found in the receiving test pattern only.

BER Threshold : Enter the threshold amount as follows (if the bit error
results exceed this value, the test will be declared as failed):

If the Pass/Fail Verdict is Bit Error Count , the accepted threshold
range is
0
to
999999
with a default value of
0
.

If the Pass/Fail Verdict is Bit Error Rate , the accepted threshold
range is
1.0E-14
to
1.9E-01
with default value of
1.0E-12
.

The Pass/Fail Verdict is displayed on the screen with the help of
the following icons:
= Pass
= Fail
