In the AutoCal-specialized version, adapter removal primarily refers to the case of a gender incompatibility when it is not desired to use test port converters (for example, an M-F AutoCal unit used to establish M-M reference planes). A separate menu item shown below (see Figure: AutoCal Setup Dialog with Adapter Removal Selected) is provided for AutoCal adapter removal to speed up the process since fewer manual steps are needed. In this calibration sequence, an adapter that can mate the desired reference plane connectors is used as a part of the calibration.

There are two possible ways to accomplish this, both using a pair of calibration sequences to remove the effects of the adapter. In both of the cases below, it is assumed all connectors are from the same family. If not, as with a special inter-series AutoCal unit, this AutoCal-specific adapter removal technique cannot be used. Instead, see the standard adapter removal section.

For an example of the mechanics of the AutoCal module and adapter calibration process, see the figure below (Figure: AutoCal M-F Module, M-M Reference Planes, and Adapter Removal Calibration). Other example figures are available in AutoCal Procedures:

The figure below (Figure: AutoCal M-F Module, M-M Reference Planes, and Adapter Removal Calibration) shows a typical M-F AutoCal Module with M-M reference planes.
