Setup

The

Setup

screen allows configuration of the ATS-5X line interface. Although Figure 22 shows one example of a

configuration, the content and available selections on the screen are dependent upon the measurement mode
previously selected. The ATS-5X line interface is influenced by the setup options as shown in Figure 20 and Figure 21.
