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 following

conventions:

 Instructions for menu selection follow this format:   *

" "' '&&#" "' '&&#". For example, Press

%#"%& &# &#$)."

 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.

 Instruction steps are numbered unless there is only one step.

#' %

Throughout this manual, any replaceable component, assembly, or part of

the AWG2005 is referred to generically as a module. In general, a module is

an assembly (like a circuit board), rather than a component (like a resistor or

an integrated circuit). Sometimes a single component is a module; for

example, the chassis of the AWG2005 is a module.

&)

Symbols and terms related to safety appear in the   near the

beginning of this manual.

Other documentation for the AWG2005 Arbitrary Waveform Generator inĆ

cludes:

 The    contains a tutorial to quickly describe how to

operate the AWG2005. It also includes an inĆdepth discussion on how to

more completely use AWG2005 features.

 The     explains how to control the

AWG2005 with a computer through the GPIB or RSĆ232ĆC interface.
