RF devices installed in the EX7000. To control a switch, for example, simply click on the pin that

other RF devices, certain values may need to be entered or selected in order for them to perform as
required. Horizontal and vertical scroll bars allow the user to navigate larger systems by scrolling.

a size selection menu. By clicking on either the up or down arrow, the size of the schematic can be
changed from to any of the following sizes: Tiny, Small, Medium (default), and Large.
