The SDI/Bullseye Tab

The SDI/Bullseye tab (Figure 6–8) allows you perform loopback tests on the Bull’s

Eye and SDI ports.

The following sections describe the controls on the SDI/Bullseye tab.

Status

The Status control displays the following status information during the loopback test:

■ PLL lock—Shows the PLL locked or unlocked state.

■ Channel lock—Shows the channel locked or unlocked state. When locked, all

lanes are word aligned and channel bonded.

■ Pattern sync—Shows the pattern synced or not synced state. The pattern is

considered synced when the start of the data sequence is detected.
