BERT and Unframed BERT

 All Lanes check box is available with an unframed test with parallel

interface. When selected, it allows to set the same TX and/or RX test

pattern for all lanes. When All Lanes check box is cleared (default), a

different test pattern may be set for each lane.

When the All Lanes check box is cleared, for an unframed test, the

following pattern settings are available for each lane.

 TX Pattern/RX Pattern: Select the test pattern from the list for each

lane and direction (TX and RX). Choices are PRBS9, PRBS11, PRBS15,

PRBS20, PRBS23, and PRBS31 (default).

 Invert check box, when selected (cleared by default), inverts the 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.

 Pattern Sync icon indicates the status of the received signal pattern.

Refer to Status Bar on page 24 for more information.

Bit Error

 Pass/Fail Verdict allows to enable bit-error-rate pass/fail verdict by

selecting either Bit Error Count or Bit Error Rate. The default value is

Disabled.

 BER Threshold allows to enter the threshold Count or Rate value that

will be used to declare the pass/fail verdict. The BER Threshold

applies to individual pattern for Multi-Pattern.

For Count, enter the maximum bit error count allowed before

declaring a fail verdict: 0 (default) to 999999.

For Rate, enter the maximum bit error rate allowed before declaring a

fail verdict: 1.0E-14 to 1.9E-01. The default value is 1.0E-12.
