The Operation | Load Active Probe menu option loads the active probe required by the measurement routine. While in Learn mode, use the Probe Utilities dialog box (Insert | Hardware Definition | Probe) to change the loaded probe file or files.
Use the Probe Changer dialog box (Edit | Preferences | Probe Changer) to define the appropriate probe configurations for each port that is used. You can then use the Load Active Probe option to tell the machine to exchange the necessary probe configuration or configurations.
