Preface
Manual Conventions
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:
Names of front panel controls and menus appear in the same case (initial capitals, all uppercase, and so on) in the manual as is used on the waveform generator front panel and menus. Front-panel names are all upper case letters (for example, SETUP, UTILITY, HARDCOPY, and so on).
Instruction steps are numbered unless there is only one step.
Modules Throughout this manual, any replaceable component, assembly, or part of the waveform generator 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 waveform generator is a module.
Safety Symbols and terms related to safety appear in the Safety Summary near the beginning of this manual.
Finding Other Information
Other documentation for the AWG400-Series includes:
The AWG400-Series user manual contains a tutorial to quickly describe how to operate the waveform generator. It also includes an in-depth discussion on how to more completely use the waveform generator features.
The AWG400-Series programmer manual explains how to use a GPIB interface to remotely control the waveform generator.

Introduction
This manual contains information that is needed to properly service the AWG400-Series Arbitrary Waveform Generators, as well as general information that is critical to safe and effective servicing.
To prevent personal injury or damage to the waveform generator, consider the following before attempting service:
The procedures in this manual should be performed only by a qualified service person.
Read the General Safety Summary and the Service Safety Summary, beginning on page xi.
Read Preparation for Use in Operating Information.
When using this manual for servicing, be sure to follow all warnings, cautions, and notes.
Performance Verification Procedures
The performance check described in the Performance Verification section should be done every 12 months. In addition, a performance check is recommended after module replacement.
If the waveform generator does not meet performance criteria, repair is necessary.
Strategy for Servicing
Throughout this manual, the term, module, refers to any field-replaceable component, assembly, or part of the waveform generator.
This manual contains all the information needed for periodic maintenance of the waveform generator. Further, it contains all information for corrective maintenance down to the module level. To isolate a failure to a module, use the troubleshooting procedures found in the Maintenance section. To remove and replace any failed module, follow the instructions in the Removal and Installation Procedures subsection. After isolating a faulty module, replace it with a fully-tested module obtained from the factory. The Replaceable Mechanical Parts section contains part number and ordering information for all replaceable modules.

Product Overview
Product Description
The AWG400-Series Arbitrary Waveform Generator is a programmable Arbitrary Waveform Generator which has a maximum 200 MS/s, 4 M word per channel waveform memory and 16-bits DAC. Amplitude is programmable up to 2.0 V (Complementary output) or {5 V (Single-Ended output) optional} peak-to-peak into 50 W with independent offset control.
The exterior of the AWG400-Series Arbitrary Waveform Generator is similar to the AWG500/AWG600-series product, except that the parameters and operating menus are displayed on an LCD color monitor instead of a monotone CRT (cathode ray tube).
The instrument can be manually controlled from the front panel and remotely programmed via a GPIB (General Purpose Interface Bus) or Network.
The AWG400-Series Arbitrary Waveform Generator GPIB is compatible with other devices that meet IEEE standard 488.2.
The AWG400-Series Arbitrary Waveform Generator allows you to create sine, triangle, square, ramp, and complex waves, as well as direct current and noise signals. It allows you to set waveform attributes, such as frequency, amplitude, and offset.
This instrument contains a hard disk drive, a 3.5-inch floppy disk drive, and an Ethernet interface for storing and recalling waveform data and instrument settings.
Main Features The AWG400-Series Arbitrary Waveform Generator contains the following main features:
200 MS/s sampling rate
16-bit DA converter
4 M-word waveform memory
Two arbitrary marker outputs per channel
Five waveform editors (see Table 1±1)

A GPIB interface that can be used for remotely controlling the AWG400-Se- ries and for transferring the waveform data from external oscilloscopes.
Refer to Connecting to a GPIB Network of The UTILITY Window of section 3 Reference on AWG400-Series user manual for information on setting the GPIB parameters.
Refer to the AWG400-Series programmer manual for information on the remote control commands.

A port on the rear panel for connecting a 101or 106-type keyboard to the AWG400-Series Arbitrary Waveform Generator. You can input values or text with the keyboard instead of using the numeric keypad on the front panel. Refer to the Reference:External Keyboards section of the AWG400-Series user manual.
An internal clock for setting up the current date and time. Refer to Internal Clock (Date and Time) in the AWG400-Series user manual. This setup procedure is also described in Tutorial 1: Instrument Setup.

Specifications
This section contains the AWG400-Series Arbitrary Waveform Generator specifications. All specifications are guaranteed unless labeled ªtypicalº. Typical specifications are provided for your convenience but are not guaranteed.
Specifications that are marked with the n symbol in the column Characteristics, are checked in the Performance Verification procedures and the page number referenced to the corresponding performance verification procedures can be found in the column PV reference page.
The characteristics in the specifications are listed in tables that are divided into categories. In these tables, the subcategories may also appear in boldface under the column, Characteristics.
Performance Conditions The performance limits in this specification are valid with these conditions:
The AWG400-Series Arbitrary Waveform Generator must have been calibrated and adjusted at an ambient temperature between +20_ C and +30_ C.
The AWG400-Series Arbitrary Waveform Generator must be in an environment with temperature, altitude, humidity, and vibration within the operating limits described in these specifications.

nContinuous |
Waveform is continuously output in this mode. When a sequence is |
Page 4-19 |
|
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. |
|
|
|
|
nTriggered |
Waveform is output only once when a trigger event is created. A |
Page 4-23 |
|
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. |
|
|
|
|
nGated |
The waveform is output in the same way as in the continuous mode |
Page 4-29 |
|
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. |
|
|
|
|
nEnhanced |
The waveforms are sequentially or repeatedly output according to |
Page 4-67 |
|
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. |
