RUN TEST
1. Tap the Signal Lead tab at the bottom of the
screen and tap the RTS and DTR buttons.
2. Press the Restart soft key .
3. Using the drop-down menus, select
“Summary/Status” for the left results display
and select “HS Datacom/BERT” for the right
results display.
4. Allow the test to run for desired duration and
verify the following:
•Pattern Sync LED is green.
•Error Rate result does not exceed
your required Bit Error Rate (BER)
threshold. (0.00E+00 if pass/fail
threshold unknown)
5. In the T-BERD’s Quick Config menu,
change “Pattern” to the next value in the
test plan.
6. Press the Restart soft key to reset
results.
7. Allow the test to run for desired duration and
verify the following:
•Pattern Sync LED is green.
•Error Rate result does not exceed
your required BER threshold.
(0.00E+00 if pass/fail threshold
unknown)
8. Repeat steps 5 through 7 for all Patterns in
the test plan.
