This manual uses certain conventions that you should become familiar with.
Some sections of the manual contain procedures for you to perform. To
keep those instructions clear and consistent, this manual uses the followin

Names of front panel controls and menus appear in the same case
(initial capitals, all uppercase, etc.) in the manual as is used on the
AWG2005 front panel and menus. Front panel names are all upperĆcase
letters; for example,    , etc.

Throu hout this manual, any replaceable component, assembly, or part of
the AWG2005 is referred to enerically as a module. In eneral, a module is
an assembly (like a circuit board), rather than a component (like a resistor or
an inte rated circuit). Sometimes a sin le component is a module; for
example, the chassis of the AWG2005 is a module.
