Heading Meanings in a DG1062Z Menu

[ximac]

Does anyone know the meaning of the headings in the 'Utility - Test Cal - Manual Cal' menus of the DG1062Z; such as 'High Freq Flat', etc? 'Ampl' is fairly obvious but not the actual attenuator settings of its 50-odd items. I have prudently left them all alone but curiosity does make me ask. Thanks - Joe.
