4.2.1 AP Connection Testing

By default, the board ships with the 2.4 GHz and 5 GHz RF signals routed to the onboard chip antenna, as shown in Figure 4-4.

A U.FL connector J17 provides a way to test in the lab using a compatible cable. Alternatively, trackpads for an SMA connector J15 are provided onboard to replace the J17 U.FL connector for testing conducted measurements. A rework must be performed before these connectors can be used; this involves swapping the position of a resistor. Figure 4-5 shows the modified board.
