The Display Format Menu

The @GET) 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 illustrations below show a reflection measurement of a bandpass hlter displayed in each of
the available formats

Log Magnitude Format

used to display magnitude-only measurements of insertion loss, return loss, or absolute power
in dB versus frequency. F'igure 6-12 illustrates the bandpass filter reflection data in a log
magnitude format.
