This tab has the following fields:
-
BERT-error-rate (rate) —Bit error rate (10^-n for n > 0, and zero for n = 0) (0-7)
-
Remote-Loopback-Respond —Respond to loop requests from remote end.
-
BERT-period (seconds) —Length of BERT test (1-240 seconds)
-
Invert Data —Check to invert data.
-
BERT-algorithm —Use the pick list to set the BERT algorithm. The following are available
options:
all-ones-repeating–Repeating one bits
all-zeros-repeating–Repeating zero bits
alternating-double-ones-zeros–Alternating pairs of ones and zeros
