Agilent Technologies 1670G-Series Logic Analyzers

The Agilent Technologies 1670G-Series is a 150-MHz State/500-MHz

Timing Logic Analyzer with a VGA resolution color display. The 1670G-

Series logic analyzer has two options available. One option is to add a

2 GSa/s digitizing oscilloscope. Another option is to add a 32 channel

pattern generator.

In This Book

This User’s Guide has three sections. Section 1 covers how to use the

1670G-series logic analyzers. Section 2 covers how to connect, use, and

troubleshoot the logic analyzer via a Local Area Network (LAN)

connection. Section 3 covers the features of the Agilent Technologies

Symbol Utility software.

Section 1. Chapters 1 through 4 cover general product information

you need to use the logic analyzer. Chapter 5 and 6 contains detailed

examples to help you use your analyzer in performing complex

measurements. Chapter 7 covers how to use the oscilloscope (Option).

Chapter 8 covers how to use the pattern generator (Option). Chapters

9 through 11 contains reference information on the hardware and

software, including the analyzer menus and how they are used.

Chapters 12 through 14 provides a basic service guide.

Section 2. Chapters 15 through 16 provides information about

connecting the logic analyzer to the network. Chapter 17 shows you

how to access the logic analyzer’s file system. Chapter 18 shows you

how to display the analyzer interface on an X Window server. Chapter

19 shows you how to retrieve measurement data, screen images, and

status information from you logic analyzer on the LAN, and how to

copy and restore configurations. Chapter 20 shows you methods for

programming the logic analyzer via the network connection. Chapter

21 contains additional information on the logic analyzer’s directory

structure and dynamic files. Chapter 22 describes what to do if you

have a problem using the logic analyzer on your network.

Section 3. Chapters 23 through 24 describe how to locate the menus

associated with the Symbol Utility. Chapter 25 describes how to use the

Symbol Utility to perform common tasks. Chapter 26 describes the

features and functions of the Symbol Utility.
