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 to enable and configure 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).

BER Threshold allows to enter the threshold Count or Rate value that
will be used to declare the pass/fail verdict.
For Count, enter the maximum bit/pattern error count allowed before
declaring a fail verdict: 0 (default) to 999999.
For Rate, enter the maximum bit/pattern error rate allowed before
declaring a fail verdict: 1.0E-14 to 1.9E-01. The default value is 1.0E-12.
