LED Panel
The LEDs in the panel to the left of the Results Windows help you determine whether
a signal is present, pattern synchronization has been achieved, and other key events
when performing tests.
You can collapse and expand an LED panel by tapping the panel name (for example,
Ethernet).
For descriptions of each of the LEDs, refer to the Test Results chapter in the testing
manual that shipped with your instrument.
The round LEDs on the inside column provide the current state of the key event; the
square LEDs on the outside column provide the historical state (in other words, the
event occurred in the past).
Green LEDs indicate an event occurred as expected, yellow LEDs indicate that an
event occurred that warrants additional investigation, and red LEDs indicate that an
error, anomaly, alarm, or defect has occurred.
Actions Panel
After you select a test application (using the Test menu), an Actions Panel appears
under the LED display that provides tabs with the buttons required to perform your test.
The buttons available vary depending on the test application you select. For example,
buttons may appear that allow you to start and stop transmitting Ethernet traffic, and
start and stop a local loopback.
A blinking circle on a tab indicates that some action is required on your part. For
example, if you are running a BERT test, the Actions tab may blink indicating that you
need to start transmitting the BERT pattern.
If you select a test application for an optical rate, a Laser / Tx Signal tab also appears,
with buttons that allow you to select an SFP connector for the test (if appropriate), and
turn the laser on and off.
Results Buttons
Group and Category buttons are provided at the top of each result window. The Group
button on the left allows you to select the type of results you want to observe (for
example, Summary results); the Category button on the right allows you to select a
specific results category for the group you specified. By selecting a different group or
category for each pane, you can view multiple sets of results at the same time.
Results Windows
The test results appear in Result Windows.
Errors are highlighted in red; other results appear in black.
