Analyzer Display Formats
The key accesses the format menu. This menu allows you to select the appropriate display format
for the measured data.
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 following illustrations show a reflection measurement of a bandpass filter displayed in each of the
available formats.
Log Magnitude Format
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. The bandpass filter reflection data in a log magnitude format is illustrated in
Figure 7-6.
