Test Patterns

Use the Test Pattern commands to send, monitor, and
abort test patterns. Available test patterns are:
QRSS – A quasi-random signal source
approximating live data that can be monitored for
logic errors.
1-in-8 – A test pattern consisting of a one (1)
followed by seven zeros.

Sending Test Patterns

Use the Send command to start transmission of a test
pattern. Only one test pattern can be active at a time.
To send a test pattern,
1. From the top-level menu screen, select Test.
2. From the Test screen, select Ptrns.
Test:
Rlpbk Lpbk
F1
3. From the Patterns screen, select Send.
Patterns:
Abort

4. From the Patterns Send screen, press F1 to send a
QRSS pattern or F2 to send a 1-in-8 pattern.

If the CSU is already sending the test pattern you
selected, the message Already active appears. If
you selected more than one test pattern, the
message Invld Test Combo appears.

Monitoring Test Patterns

Use the Monitor command to monitor a QRSS test
pattern on the network interface.
This command provides the number of errors detected
in the test pattern (5 digits, maximum 99999).
To monitor a QRSS test pattern,
1. From the top-level menu screen, select Test.
2. From the Test screen, select Ptrns.
Test:
Rlpbk Lpbk
F1
3. From the Patterns screen, select Mon.
Patterns:
Abort
F1
The Monitor screen appears with the error count.
If the maximum of 99999 is exceeded, OvrFlw
appears instead of the count. If the receiver loses
synchronization while the monitor is active, No
Sync appears.
