About this Manual
We’ve added this manual to the Agilent website in an effort to help you support
your product. This manual is the best copy we could find; it may be incomplete
or contain dated information. If we find a more recent copy in the future, we will
add it to the Agilent website.
Support for Your Product
Agilent no longer sells or supports this product. Our service centers may be able
to perform calibration if no repair parts are needed, but no other support from
Agilent is available. You will find any other available product information on the
Agilent Test & Measurement website, www.tm.agilent.com.
HP References in this Manual
This manual may contain references to HP or Hewlett-Packard. Please note that
Hewlett-Packard's former test and measurement, semiconductor products and
chemical analysis businesses are now part of Agilent Technologies. We have
made no changes to this manual copy. In other documentation, to reduce
potential confusion, the only change to product numbers and names has been in
the company name prefix: where a product number/name was HP XXXX the
current name/number is now Agilent XXXX. For example, model number
HP8648A is now model number Agilent 8648A.

In This Book
This User’s Guide shows you how to
use the HP 1660CS-series logic
analyzer. It contains measurement
examples, field and feature
definitions, and a basic service guide.
Refer to this manual for information
on what the menu fields do and how
they are used. This manual covers all
HP 1660CS-series analyzers.
The User’s Guide is divided into four
parts. The first part, chapters 1
through 4, covers general product
information you need to use the logic
analyzer. The second part, chapters
5 and 6, contains detailed examples
to help you use your analyzer in
performing complex measurements.
The third part, chapters 7 through 9,
contains reference information on the
hardware and software, including the
analyzer menus and how they are
used. There are sections for each
analyzer menu and a separate
chapter on System Performance
Analysis. The fourth part, chapters 10
through 12, provides a basic service
guide.

Logic Analyzer Overview

HP 1660CS-Series Logic Analyzer
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.
Shift 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 — just 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.
1-2

Line Power Module
Permits selection of 110-120 or 220-240 Vac and contains the fuses for each
of these voltage ranges.
External Trigger BNCs
The External Trigger BNCs provide the "Port In" and "Port Out" connections
for the Arm In and Arm Out of the Trigger Arming Control menu.
RS-232-C, HP-IB, and Parallel Printer Connectors
The RS-232-C connector is a standard DB-25 connector for RS-232-C printer
or controller. The HP-IB connector is a standard HP-IB connector for
connecting an HP-IB printer or controller. The Parallel Printer connector is a
standard Centronics connector for connecting a parallel printer.
Oscilloscope Calibration Ports
Provides signals for operational accuracy calibration for the oscilloscope and
the oscilloscope/probe together to optimize performance.
LAN Connectors (with LAN option only)
Connects the logic analyzer to your local Ethernet network. The BNC
connector on top accepts 10Base2 ("thinlan"). The UTP connector below the
BNC connector accepts 10Base-T ("ethertwist").

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 a preprocessor 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" in Chapter 7 for more detail on grounding and 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.
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.
* If you load a configuration file, this step is not necessary.
Logic Analyzer Overview
To make a measurement
1-4

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 Format Menu" in Chapter 7 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.
* If you load a configuration file, this step is not necessary.
