Example 2B: 1-Port Calibration
The following is an outline of the program's processing sequence:
• An I/O path is assigned for the analyzer.
• The system is initialized.
• The appropriate calibration kit is selected.
• The softkey menu is deactivated.
• The 1-port calibration sequence is run.
• The 1-port calibration data is saved.
• The softkey menu is activated.
• The analyzer is released from remote control and the program ends.
