By default, co-calibrated ports are automatically grouped with other co-calibrated ports by the software. However, it is possible to create a calibration group to which you manually assign ports. A manually created calibration group overrides the auto grouping.
For a discussion of the rules which apply to manual grouping, please refer to Rules for Co-calibrated Ports.
To manually assign a calibration group to co-calibrated ports in your circuit, do the following:
- Select the co-calibrated ports for which you wish to create a group.
They should appear highlighted in your circuit.
- Select Object ⇒ Port Properties from the main menu.
The Port Properties dialog box appears on your display. You may also open this dialog box by double-clicking or right-clicking on a port and selecting Port Properties from the popup menu. "Mixed" is displayed as the port number since you have multiple ports selected.
- Select a Calibration group name from the Calibration group name drop list.
The names are automatically generated by the project editor. If you are starting a new calibration group, select the first name in the list. If you wish to add these ports to an existing manually defined calibration group, then select the name of the group from the drop list.
- Select the desired ground reference from the drop list.
There are three different types of ground reference for a calibration group: Box Cover, Polygon Plane, or Floating. You may also select Auto to allow the software to determine the ground reference. For more information on ground references for calibration groups, see Calibration Group Properties.
- Select the Terminal Width setting for your calibration group from the drop list.
Terminal width is the electrical contact width of the element. There are three different settings for terminal width: Feedline Width, One Cell and Custom. For more information on terminal widths, see Calibration Group Properties.
- If you wish, define Reference planes for the ports.
For more information on setting up reference planes, see Reference Planes and Calibration Lengths for Co-calibrated Ports.
- When you have finished defining your settings, click on the OK button of the Port Properties dialog box.
The dialog box closes and the ports are redrawn with a group identifier. This completes the addition of a manually created calibration group.
