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.

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•

Agilent LXI solutions

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.
