This chapter provides information per-port power and, if equipped, attenuator configurations for the VNA in 2-Port Mode. The Power menus and associated field toolbars allow the user to set various power mode parameters. The settings on the Power menus apply to the currently active channel. The power menus, their link structure, appearance, and related dialog boxes vary depending on the setting of the SWEEP TYPE menu as either: Frequency-Based Sweep (Linear or Log), Segmented-Based Sweep (Frequency- or Index-Based), or Power-Based Sweep (CW Frequency or Swept Frequency). Note that the menu appearance, button availability, and hierarchical links change if the VNA is in 4-Port Mode. For 4-Port Mode power menus, see Power Menus - 4-Port VNAs.
