The GXB SMA Tab

The GXB SMA tab allows you to run transceiver SMA loopback tests on your board.

You can also load the design and use an oscilloscope to measure an eye diagram of the

SMA transmit signals. Figure 6–5 shows the GXB SMA tab.

The following sections describe the controls on the GXB SMA 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 for multi-channel

designs only. 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.
