The far field viewer display defaults to a cartesian plot with theta selected on the<br />

X-axis. The polarization defaults to Theta/Phi. The Y-axis is set to display the<br />

Gain (in dB) of the pattern response and is normalized to power gain of the ideal<br />

isotropic antenna.<br />

To change the calculation and display defaults, see File - Preferences in the far<br />

field viewer’s help.<br />

Calculating the Response<br />

As mentioned above, when the far field viewer is invoked, the response data is calculated<br />

for only the first frequency in the current response file. To calculate data<br />

for the other frequencies at additional angles, perform the following:<br />

5 Select Graph ⇒ Calculate from the far field viewer main menu.<br />

The Calculation Setup dialog box appears on your display with the Angles tab selected<br />

as shown below.<br />
