Sending a Test Pattern
The
DL600E
unit can also send test patterns to the network port. These
patterns can be sent over the full bandwidth or over only a fraction of
the bandwidth.
While sending the test pattern, the
DL600E
unit tries to lock on to the
same pattern from the remote unit. It remains in this state until it
achieves a lock or until you terminate the test.
When the DL600E unit achieves a lock with the signal from the remote
unit, it displays:
PATTRN 0
As it detects errors in the received pattern, it displays the number of
received errors on the front panel. The error count starts at
0
and can
reach a maximum of
65,535
. If it loses the pattern lock, it resumes
searching.
