Performing tests

The following section addresses questions that may be asked about completing tests
with the instrument.

Test menu does not appear

Your instrument may be configured to display the Quick Launch screen by default
(instead of the Main screen). If this is the case, on the Quick Launch screen, select the
All Tests button. The Test menu will appear to the left of the screen.

Application does not appear on the Test menu

Verify the following:
• Ensure that the required test option is installed. For example, if you are looking for
MiM (PBT) applications, or if you do not see the settings required to verify layer 2
transparency, verify that the associated test option has been installed.
• If you are testing using an MSAM, ensure that the appropriate PIM is inserted in
the MSAM chassis. For example, to see DS1 applications, a DS1 PIM must be
inserted into a port on the chassis. If an SFP PIM is inserted, the DS1 applications
will not appear.

Optical Overload Protection is activated

When testing on an optical circuit, the instrument displays a warning that the Optical
Overload Protection is activated, or the instrument does not detect a signal.
Verify that the applied power does not exceed the power level supported by the
connected transceiver. If it does, attenuate the signal.

MSAM or CSAM user interface is not launching

After verifying that the appropriate BERT icon is highlighted in yellow with a green
outline, press the Results or the Start/Stop key to display the MSAM, or CSAM user
interface.
The green outline indicates which particular BERT module the instrument is currently
displaying the user interface for (in other words, it is the module in focus). A yellow icon
without a green outline indicates that the BERT module is active, but that the user inter-
face is not displayed.
