Getting There Just Got Easier
Agilent 1680 and 1690 Series Logic Analyzers
Solve critical digital design problems faster
Getting there just got easier
When you’re debugging a design, you need to focus on solving your problems—not on mastering
your debug tools. That’s the thinking behind Agilent Technologies’ new 1680 and 1690 series of
logic analyzers. These instruments work intuitively, so you can answer critical design questions
without first becoming an expert in measurement instruments.
You’ll understand your logic analyzer right out of the box—thanks to the familiar Windows®-based
features, the easy-to-navigate interface and the straightforward triggering. High performance
doesn’t mean difficult to operate. Just turn the instrument on and you’re ready to solve.
Performance with Headroom
You get accurate and reliable measurements for today’s processors
and buses, with power to cover future technology trends:
• 200 MHz state
• Up to 800 MHz timing with 4 M of memory depth
• 200 MHz transitional timing
Instant Familiarity and Insights
The single-screen operation, intuitive triggering and familiar Windows
interface provide answers quickly and easily—so you can focus on
debugging your design.
Fitting Your Work Style
Small-footprint benchtop and PC-hosted models are available for integration
into your debug environment. And offline analysis capabilities allow you to
continue making measurements while you work at getting answers. These
instruments work the way you work.
Windows Familiarity and Single-Screen Operation
A familiar Windows-based user interface takes the complexity out of making logic analyzer
measurements. You’ll feel right at home from the moment you turn on the instrument.
And if you haven’t used your logic analyzer in a while, you won’t have to spend hours
getting reacquainted with its features.
Perform all operations directly from
the main screen—as you would with
a PC application such as Microsoft®
Word or Excel.
Access the most frequently used
features via icons.
Select advanced features from the
standard Windows menu bar.
Expand/compress buses with
Windows-like +/- symbols.
Three measurement modes
State Analysis
Transitional Timing
State analysis uses a signal from your
system under test to determine when to
sample. Because state analysis samples
are synchronous to the system under
test, they provide a view of what your
system is executing. You can capture
microprocessor and bus cycles and
then convert the data into processor
mnemonics or bus transactions with
inverse assemblers from Agilent or one
of our third-party partners.
If your system has bursts of activity
followed by times with little activity,
you can use transitional timing to
capture a longer period of system
activity. In transitional timing, the
analyzer samples data at regular
intervals but stores the data only
when there is a transition on one
of the signals.
Timing Analysis
Timing analysis uses the logic analyzer’s
internal clock to determine when to sample
system activity. With up to 800 MHz
sampling and 4 M deep memory, you’ll see
the order of events with high resolution
over a long period of time.
When you know what you want to capture,
trigger the way you think
During board turn-on and system debug, Agilent’s straightforward triggering
capabilities help you quickly narrow in on the root cause of a problem.
You can capture every aspect of your design, from a simple stuck bit to the
complex sequence of events leading up to a timing problem. The intuitive
triggering helps you identify the cause of elusive problems in less time—so
you can get to your solution quickly.
Selections for individual signals
Qualification selections for bus patterns
Simple Trigger
Set the trigger according to how you think
about your target signals. Use standard
events, such as rising edge, falling edge
or pattern, to define a trigger event.
These events are accessible via an easy
pull-down menu.
You can set the trigger for an event on the
basis of activity on one or more buses or
signals. Simply select the patterns, edge
or levels for the signals that apply.
Set Quick Trigger
See something you didn’t expect in
the current trace? Simply draw a box
around the questionable event and select
Set Quick Trigger to see if it occurs again.
You don’t have to spend time defining
the trigger. The instrument does the
work for you.
Advanced Trigger
With the Advanced Trigger, you can customize a trigger for your specific situation.
You can use trigger functions as individual
trigger events or as building blocks for
complex scenarios.
Icons provide a graphical representation
for each trigger function. Simply drag-anddrop an icon into the trigger sequence. To
fully define the trace event, fill in the
blanks with values or select standard
options from the pull-down menu.
Trigger History/Recall
Save and name each trigger to create a
series of your favorite triggers. Recall a
previous trigger to test your latest defect
fix. Have the confidence of knowing you
can make the same measurement later
without having to spend time setting up
the instrument.
Benchtop 1680 series
Agilent’s 1680 series benchtop logic analyzers feature a 12.1-inch color display and
convenient knobs and hot keys. A glance at the interface provides quick insights on
your measurements, as well as information on the status of the instrument.
The 12.1-inch color display allows you to
see more data. Viewing relationships
between large amounts of signals and
buses helps you identify a problem sooner.
Backlit LEDs show you the current logic
analyzer settings at a glance.
Front panel knobs let you quickly change
the vertical and position settings of the
display. You can accurately place unlimited
markers to make critical timing measurements.
Cable flexibility allows you to conveniently access your target from the front or
back of the benchtop 1680 series.
A Default Setup key returns the logic
analyzer to a known state—an important
feature if you share your logic analyzer.

Connecting to your world
Each measurement you take provides
additional clues to the cause of your
design problems. Because access to your
captured traces and the answers they
provide is critical, your Agilent 1680 series
benchtop logic analyzer gives you several
options for data storage, retrieval and
A 10/100Base-T LAN interface lets you
easily print waveforms on networked
printers, save your results on your office
PC, and share information with others.
The hard-drive capacity—15 GB minimum—allows you to store all of your
setups and results for future recall.
The 1.44 MB floppy drive makes it easy
to save your setups to standard 3.5-inch
floppy disks.
Two IEEE 1394 ports enable connection
of external hard drives or read/write
CD-ROM drives for data storage and
Two USB ports enable the hot connection
of mouse or keyboards.
A mouse lets you point and click with
ease, or you can choose a different pointing device that best meets your needs.
A small keyboard is standard.
Trigger In/Trigger Out BNCs allow you
to trigger or arm external devices and to
receive signals that can be used to arm
the logic analyzer.
A parallel printer port lets you print
hard copies of screen graphics for project
An external video port allows you to
connect large displays.
A 24x CD-ROM drive is used to update

PC-hosted 1690 series
Agilent’s 1690 series PC-hosted logic analyzers provide the lowest price point for
high-performance logic analysis. They allow you to carry out your debug work in
your familiar PC environment.
An IEEE 1394 port provides direct connection to a 500 MHz minimum Intel® Celeron
or AMD K-6 II (or equivalent) PC running
Windows 2000 Professional. Purchase
additional quantities of E5851A (IEEE 1394
PCI card and cable) so the instrument can
be shared throughout the team.
PC-hosting allows you to see your design
with the same display size and resolution
of your regular working environment.
Trigger In/Trigger Out BNCs allow you
to trigger or arm external devices and
to receive signals that can be used to
arm the logic analyzer.
Access to your captured traces, your ability
to store and retrieve data, and your print
capabilities depend on your PC and network
A smaller footprint saves valuable workspace
and makes for easy portability.
Cables connect conveniently to your
target from the front of the analyzer.
