2.16.2.1.15 Spectrum element

The Spectrum Display element embeds the spectrum display of a spectrum analyzer device in the screen. The display may be scaled to an almost arbitrary size, however the following limitations apply:

• The annotation labels which reflect the actual spectrum analyzer settings are not scaled with the display element. If the element is very small, the labels may overlap and become unreadable.
• Resizing the spectrum display element is only possible in certain steps, the grid behind the spectrum curve is always made up of 10*n + 11 pixels in one dimension. The screen editor software knows about this, snaps the size of the element to the next (smaller) valid size after you release the mouse button.

The attributes listed below may be configured to customize a display element of this type:

• Device name: The name of the spectrum analyzer device with MNC name (MNC.devicename) to operate.
• Label: The label text is drawn above the element.
• Privilege level: The privilege level necessary to operate the spectrum analyzer device.
• Font: Font contains two options:
  • Font: The font attribute applies to the text shown in the parameter field itself. The label text is shown with the standard ("plain") font size for all font selections except the smallest one. In the latter case the label is drawn using this small font size, too.
  • Color: The color attribute of a element sets the color of the label shown above the entry field. The text in the parameter field itself always is shown in the default text color of the selected look & feel. Colors may be specified by using a hexadecimal RGB notation. You may click to the color example field in order to open a color chooser dialog and select the color from there.
