Test Setup - Test Configurator, Timer, and System
80 MAX-800 Series
BERT and Unframed BERT
For Multi-Pattern, see Multi-Pattern Configuration on page 84.
When User Pattern is selected, enter the payload pattern hexadecimal
value.
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. Patterns PRBS15,
PRBS23, and PRBS31 are defined inverted as per ITU standard and
EXFO uses inverted patterns for Transport test applications excluding
EoOTN. Not available when pattern is Multi-Pattern.
All Lanes check box is available with an unframed test with parallel
interface. When selected, it allows setting 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 (see
page 79) for each lane and direction (TX and RX).
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 20 for more information.
Bit Error
Pass/Fail Verdict enables or disables the bit-error-rate pass/fail verdict
by selecting either Bit Error Count, Bit Error Rate (default), or
Disabled.
BER Threshold allows entering 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.
