Once the test set has successfully connected the data call you can select a BERT pat-
tern (2047, 511, ALT, 1’s) from the BERT pull-down menu (2047 most common). The

If the
BERT pattern is green this tells the user that the selected pattern matches the
receive pattern. The number to the right of the pattern (0) is the bit error count. You
can change the error count display by tapping on the count pull down menu and select-
ing one of the following:
►
Bits
– (default), view the number of bits in error
►
BER
– View the bit error rate (bits in error/total bits) since the start of the test
