Signal Structure

If you are running a SONET, SDH, or OTN application, a Signal Structure tab appears
to the right of the Quick Config tab. When selected, the tab shows the structure of the
signal transmitted from the unit to the device under test (DUT) and then to another
device on the far end of the circuit (typically another test instrument).
trates the signal structure when you transmit a Bulk BERT payload in an STS-12c signal
carried in an OC-48 wrapper.

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
have occurred when performing tests. The color of the Summary LED at the top of the
panel indicates the overall status of Summary test results supporting the application.
