BERT
The Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER)
on the selected HSU port. The patterns that can be selected are off, mark (1111), space (0000),
1:1 (1010 alternating), 1:7 (0100-0000), 511 (511 test pattern), qrss (quasi-random signal
source), and 2047 (2047 test pattern).
Action Function
Save Saves changes to settings.
Undo Returns all settings to the last saved state.
Refresh Updates certain time-related information fields that are not automatically
updated (i.e., performance and test data).
InsertErr Allows you to manually insert a single error into the clear data signal.
Clear Clears the Test Screen and resets all counters to zero.
Main Returns to the PM-IOR Card Main Screen. If changes are made to settings and
not saved, you will be prompted to save or lose changes.
