Administrators and Engineers use the Create button to create tests for selected products. The Create button allows for creating Test Scripts (.RO extension) and Address Correspondence Table files (.ACT extension). The ACT file enables users to associate Analyzer I/O assignments to test connector pin assignments. Users may also import a connector pin assignment or a wire list created previously on an external platform. ACT and RO files are editable ASCII text files and may be edited in any ASCII editing software. See DIT-MCO document 132-06047-006 NETS Programming Manual for more information on creating NETS test scripts and other files.
