1 Introduction
This document provides instructions on how to operate the SMB1360 evaluation board.
The evaluation board includes both WLP and QFN (factory evaluation only; not in production)
versions of the SMB1360 IC, in two separate sections of the PCB (see Figure 1-1). Silkscreened
white lines make the sections. This document will cover the WLP section only.

2 Getting Started
Before beginning the evaluation of the SMB1360, the GUI software needs to be installed. To
install the GUI, double-click the setup.exe file. The information window shown in Figure 2-1
will appear, click Next.
Figure 2-1 GUI installation screen
The next screen (Figure 2-2) selects the destination folder that the GUI resides in. This location is
where all the drivers for the GUI are located. By default the destination folder is
C:\Program Files (x86)\Qualcomm Technologies Inc\Qualcomm SMB1360 GUI\SMB1360 GUI.
Click Next to continue the installation. Click Next again to confirm.
