2.4 Conducted RF Testing

The LP-EM-CC35X1 can be used to test RF capabilities, using Radio Tool. For more information on Radio Tool and where to download, refer to Section 2.5.1.

As seen in Figure 2-26, the LP-EM-CC35X1 has an on-board SMA connector and component antenna. The SMA connector (J1) provides a way for testing conducted RF measurements. Alternately, a track pad for a U.FL connector (J2) is provided on-board to replace the SMA connector and provide a way to test in the lab using a compatible cable (see Figure 2-26 ). A rework is needed before using the connector on J1/J2. This involves swapping the position of the existing 3.9pF capacitor to lead the transmission line on the desired connection (see Figure 2-26).
