4.1 Inputs and Outputs

The input/output connection slots were designed to fit the following connections: vertical SMA, horizontal SMA, wires, or through-hole test points. Examples of these four connectors are shown in this section.

The SMA recommended for this board is TE Connectivity part number 5-1814400-1.

Figure 46 shows SMA vertical connectors attached to both the input and output terminal.
