
No Pattern Analysis (Live) check box when cleared (default; selected
by default for framed CPRI), monitors the incoming traffic pattern and
Round-Trip Latency. For live traffic, the
No Pattern Analysis (Live)
check box should be selected as the traffic is a live pattern and in this
case no monitoring is required. Even if this check box is not available
for FC BERT, the received traffic pattern and Round-Trip Latency are
monitored. See
BER on page 350 for more information.

Invert
check box, when selected (cleared by default), inverts the
generated/expected test pattern meaning that every 0 will be changed
for 1 and every 1 for 0. For example, the pattern 1100 will be sent as
0011.
Bit/Pattern Error
The configuration of Bit Error is available with all patterns at the exception
of
Seed A
and
Seed B
for which
Pattern Error
is available.

Pass/Fail Verdict allows enabling and configuring bit/pattern error
rate/count threshold prior to run the test. This allows for a simple
pass/fail verdict, leaving no room for misinterpretation of the test
results. To enable the pass/fail verdict, select either
Bit / Pattern Error Count or Bit / Pattern Error Rate (default is
Disabled
).
