Manual Conventions
Throughout this manual you will notice the use of certain conventions. Some
sections of the manual contain procedures for you to perform. To keep those
instructions clear and consistent, this manual uses the following conventions:
Names of front panel controls and menus appear in the same case (such as
initial capitals or all uppercase) in the manual as is used on the waveform
generator front panel and menus. Front panel names are all uppercase letters;
for example, SETUP, UTILITY, HARDCOPY.
Instruction steps are numbered unless there is only one step.
Modules
Safety
Throughout this manual, any replaceable component, assembly, or part of the
waveform generator is referred to generically as a module. A module is an
assembly (such as a circuit board), as opposed to a component (such as a resistor
or integrated circuit). Sometimes a single component is a module; for example, the
chassis of the waveform generator.
Symbols and terms related to safety appear in the Safety Summary at the front of
this manual.

Product Overview
Product Description
The AWG710B Arbitrary Waveform Generator is a waveform generator that can
generate simple and arbitrary waveforms, one–channel dif ferential output arbitrary
waveforms, and function generator waveforms.
The AWG710B Arbitrary Waveform Generator allo ws you to create sine, triangle,
square, ramp, and complex waves, as well as direct current and noise signals. You
can also set waveform attributes such as frequency, amplitude, and offset.
This instrument contains a hard disk drive, a 3.5–inch floppy disk drive, and
Ethernet interface for storing and recalling waveform data and instrument settings.
You can control the instrument remotely by sending commands through both the
GPIB and 100/10BASE–T interfaces, as well as transfer waveform data directly
from a digital storage oscilloscope to the AWG710B Arbitrary Wave form
Generator using the GPIB interface. This enables you to use the instrument in
combination with other measurement equipment and a computer.
Main Features
The AW G710B Arbitrary Waveform Generator contains the following main
features:
4.2 GS/s sampling rate
8–bit DA converter
32.4 M–word waveform memory (64.8 M–word optional)
Two arbitrary marker outputs
Five waveform editors (see Table 1-1)

Editor Description
Waveform Creates analog waveform data in graphic or tabular form.
Pattern Creates analog waveform data in timing and table form.
Sequence Creates sequences of waveforms by combining the waveform files
created with the Waveform and/or Pattern Editors.
Text Edits plain ASCII format waveform files. For example, you can use
the Text editor to edit ASCII format waveform files that are read from
an external device.
Equation Creates files with equations and compiles them into waveform files.

Table 1-2: Operation modes
Characteristics Description
Continuous Waveform is continuously output in this mode. When a sequence is defined, waveforms are
sequentially or repeatedly output in the order defined by the sequence. The extended
sequence functions such as trigger input, event jump, and so on are neglected in this mode.
Triggered Waveform is output only once when a trigger event is created. A trigger signal is created by
the external trigger input signal, GPIB trigger command, and/or pressing the front–panel
FORCE TRIGGER button. The extended sequence functions such as trigger input, event
jump, and so on are neglected in this mode.
Gated The waveform is output in the same way as in the continuous mode only when the gate is
opened. The gate is opened by the gated signal.
Note that the output is made from the top of the first waveform for every gate period. The clock
signal continuously outputs from the connector outside the gate period.
Enhanced The waveforms are sequentially or repeatedly output according to the procedures defined in
the sequence. All extended functions such as trigger input, event jump, and so on are effective
and waveforms are controlled for output by this functions in this mode.
Table 1-3: Extended Operation
Characteristics Description
FG operation This mode provides user-friendliness like the conventional function generator. The output
waveforms are Sine, Triangle, Square, Ramp, Pulse and DC waveform. AWG710B is in AWG
mode when this mode is not selected.
Waveform Mixing operation This mode provides the function for mixing two-signals digitally.
Synchronous Master operation This mode provides the setup for using as a Master instrument on Synchronous Operaion.
Synchronous Slave operation This mode provides the setup for using as a Slave instrument on Synchronous Operation.
