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.

Select Key
The Select key action depends on the type of field currently
highlighted. If the field is an option field, the Select key brings up an
option menu or, if there are only two possible values, toggles the value
in the field. If the highlighted field performs a function, the Select key
starts the function.
Done Key
The Done key saves assignments and closes pop-up menus. In some
fields, its action is the same as the Select key.

The Shift key, which is blue, provides lowercase letters and access to
the functions in blue on some of the keys. You do not need to hold the
shift key down while pressing the other key. Press the shift key first,
and then the function key.
Knob
The knob can be used in some fields to change values. These fields are
indicated by a side view of the knob placed on top of the field when it is
selected. The knob also scrolls the display and moves the cursor within
lists. If you are using a mouse, you can do the same actions by holding
down the right button of the mouse while dragging.

Logic Analyzer Overview
Agilent Technologies 1670G-Series Logic Analyzer
To make a measurement
For more detail on any of the information below, see the referenced
chapters or the Logic Analyzer Training Kit. If you are using an analysis
probe with the logic analyzer, some of these steps may not apply.
Map to target
Connect probes
Connect probes from the target system to the logic analyzer to
physically map the target system to the channels in the logic analyzer.
Attach probes to a pod in a way that keeps logically-related channels
together. Remember to ground the pod.
See Also "Probing" on page 248 for more detail on constructing probes.
Set type
When the logic analyzer is turned on, Analyzer 1 is named Machine 1
and is configured as a timing analyzer, and Analyzer 2 is off. To use
state analysis or software profiling, you must set the type of the
analyzer in the Analyzer Configuration menu. You can only use one
timing analyzer at a time.
29
Logic Analyzer Overview
Agilent Technologies 1670G-Series Logic Analyzer
Assign pods
In the Analyzer Configuration menu, assign the connected pods to the
analyzer you want to use. The number of pods on your logic analyzer
depends on the model. Pods are paired and always assigned as a pair to
a particular analyzer.
Set up analyzers
Set modes and clocks
Set the state and timing analyzers using the Analyzer Format menu. In
general, these modes trade channel count for speed or storage. The
state analyzer also provides for complicated clocking. If your state
clock is set incorrectly, the data gathered by the logic analyzer might
indicate an error where none exists.
See Also "The Analyzer Format Menu" on page 297 for more information on
modes and clocks.
Group bits under labels
The Analyzer Format menu indicates active pod bits. You can create
groups of bits across pods or subgroups within pods and name the
groups or subgroups using labels.
