The chapter describes the general display options of the MS4640A Series VNA and provides a general description of the MENU BAR, the ICON TOOLBAR, and the right-side function menus. General descriptions and procedures are provided for channel setup, trace graph setup, marker setup, and limit line setup. The MS4640A Series VNA displays measurement data using a “Channel Concept” where each channel can display both a different S-Parameter (or another specialty parameter) and a different graph type. As each channel is selected, the previously selected trace graph types, scaling, reference delay, S-Parameter, and other parameters associated with that channel appear on the screen. In addition, the same S-Parameter can be displayed simultaneously on two or more channels using the same or different trace graph types.
