INAR0Y05 The Digitizer Control dialog box is unique for each board, and provides digitizer
control options available for your particular board. Choose among the various tabs

R M MdigReference(), or MdigChannel()). Using the tabs to control the digitizer
settings allows you to quickly find the exact value required for each setting, and
