The LXI Standard: A few key facts
The benefi ts: How LXI enables better systems
Three classes
LAN eXtensions for
Instrumentation (LXI) is the power
of Ethernet and the Web applied to
test and measurement. Built on proven,
widely used standards, this versatile
architecture enables fast, effi cient and
cost-effective creation and reconfi guration
of test systems. By standardizing and
extending LAN, LXI offers new possibilities
in test systems — local, remote,
distributed and time-aware.
LXI is built on the proven LAN standard, which has a long and stable history. Even as the computer industry
continues to improve LAN, it has maintained backwards compatibility with previous versions of the standard.
This open architecture helps you get your system up and running sooner—and in less space.
With LXI, it is easier for you to integrate a reliable, fast test system today and revise it in the future.
The LXI standard defi nes three classes that provide
different levels of functionality.
Reduce test-system set-up timeAutomatic instrument discovery and addressing•
No cardcage or slot 0 controller to integrate •
Standard instrument drivers•

Build versatile systems that accommodate future needs Keep pace with evolving measurement standards by simplifying the task of integrating
new instruments and new capabilities.
Go wireless or connect via fi ber in diffi cult environments•
Reuse hardware and soften the impact of software changes in future systems •
Download new capabilities or personalities into intelligent instruments •
Improve system throughput
Use Gigabit LAN to enable more than 100 times the throughput of GPIB •
Reduce programmatic wait states using peer-to-peer communication between LXI modules (class B• )
Leverage hardware and software from R&D to manufacturing
Reduce software costs by using a common set of test-system software across your organization—•
R&D, design validation, manufacturing and service
Gain geographic fl exibility
Place test systems virtually anywhere on your network •
Centralize troubleshooting and measurement monitoring•
Tap the expertise of test-system specialists in your company—worldwide•

LXI advanced capabilitiesThe LAN connectivity requirement of LXI enables
advanced capabilities:
Smart, interactive Web pages: Monitor and
control your instrument from the instrument web page.
Easy set up and Compatibility Modes:
Setup is simplifi ed with utilities that fi nd, confi gure and verify connectivity of LAN and GPIB instruments.
Agilent LXI instruments include compatibility modes to simplify the move from GPIB to LXI and from older models.
Smart instruments: built-in intelligence LXI-compliant instruments have built-in processors that enable a variety of
advanced or “smart” capabilities that can enhance overall system performance:
Pre-download measurement or stimulus sequences•
Communicate directly between instruments•
Move alarm conditions into the instrument for faster program fl ow•
Enable faster test execution with LAN and IEEE-1588 triggers•
Agilent is the leader in LXI instruments and in guiding industry test-and-measurement
Standards. All instruments listed are class C compliant except where indicated.

LXI provides triggers beyond those available
in GPIB, VXI, or PXI.
For faster test execution, peer-to-peer and multi-cast trigger capabilities allow
instrument-to-instrument communication.
The combination of time synchronization and time stamping aligns events across
instruments during operation; it also helps simplify debugging and code tuning
during system development.
A hardware trigger bus provides precise synchronization and triggering
of co-located instruments.

Making the transition to an LXI-based system is as simple as moving your existing test equipment to your
LAN, which becomes the backbone of your system. Agilent provides tools, gateways and converters
that make it easy to use your existing test assets alongside next-generation instruments within a single
system. Our converters and gateways also make it easy to connect existing equipment to the LAN without
requiring changes to your test software. Minimal programming changes are necessary when you move
Agilent instruments from GPIB to LAN, due to built-in compatibility modes. Over time—and as even more
devices become available—you can make a complete transition to LXI instruments.
