The Format Menu

The @GGZ) key provides access to the format menu. This menu allows you to select the appropriate display format for the measured data. The following list identifies which formats

are available by means of which softkeys: / .““‘::~.:; * .:.:.::.,.

The analyzer automatically changes the units of measurement to correspond with the displayed format. Special marker menus are available for the polar and Smith formats, each providing several different marker types for readout of values.

The selected display format of a particular S-parameter or input is assigned to that parameter. Thus if different S-parameters are measured, even if only one channel is used, each parameter is shown in its selected format each time it is displayed.

The ilhrstrations below show a reflection measurement of a bandpass filter displayed in each of the available formats.

The ~~~~~~~ softkey displays the log magnitude format. This is the standard Cartesian format used to display magnitude-only measurements of insertion loss, return loss, or absolute power in dB versus frequency. F’igure 6-11 illustrates the bandpass Nter reflection data in a log magnitude format.
