Pattern
 Coupled RX to TX check box, when selected (default), couples both
the TX and RX signal with the same test pattern. The Coupled RX to
TX check box is selected and not configurable for Seed A, Seed B, and
PRBS31 Unscrambled patterns as well as for Wireless CPRI/OBSAI
BERT test.
 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 296 for more information.
 TX Pattern/RX Pattern: Select the test pattern from the list for each
direction (TX and RX) if required. Choices are PRBS9, PRBS11,
PRBS15, PRBS20, PRBS23, PRBS31 (default), Seed A

, and User Pattern.
When User Pattern is selected, enter the payload pattern hexadecimal
value.
 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.
