The XCVR3 Tab

The XCVR3 tab allows you to perform loopback tests on the SMA port. Figure 6–9

shows the XCVR3 tab.

1 The external loopback mode will not pass due to only having a transmit port

available. To test in internal loopback, adjust the setting using the PMA button (serial

loopback = 1).

The following sections describe the controls on the XCVR3 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, and all TX and RX PLL lanes are

phase locked to data; RX lanes are word aligned and deskewed.
