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.
