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 6–6 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. 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.
