Agilent L4451A

4-Channel Isolated D/A Converter

with Memory

Data Sheet

• LXI compliance includes built-in

Ethernet connectivity

• Fully-featured graphical web

• Four isolated analog outputs

4-Channel D/A Converter offers high-

voltage analog outputs wherever your

application needs it

The Agilent L4451A is a high-perfor-

mance 4-channel D/A converter that

is LXI Class C compliant. With its small

size and Ethernet connectivity, the D/A

converter can be placed wherever your

application needs it.

The Agilent L4451A has four isolated

analog channels that are useful to

source bias voltages to your device

systems. You can use the standard

waveforms provided or create your own

with over 500,000 points. These points

Using this LXI instrument, you’ll get all

the benefits of an Ethernet connection,

dard software drivers and more. The

LXI standard is supported by multiple

vendors, enabling lower cost of test

with accelerated test integration and

Isolated analog outputs can be

stacked for higher voltage outputs

channels, they can be stacked to create

waveforms with higher output voltages.

Each channel can be controlled manu-

ally, or use the onboard memory to

download a waveform. The 500 k global

memory can store up to 32 waveforms.

Any waveform can be dynamically

allocated among one or more channels

and output as a point-to-point arbitrary

waveform generator at up to 200 k

Synchronize your outputs with the

CLK that can be divided down for each

channel independently.

The L4451A is electronically calibrated

using an external DMM and the CAL

System connections you can trust

The L4451A comes with 1 heavy duty

50-pin Dsub connector that allows for

simple, reliable connection options.

• Low-cost, standard 50-pin Dsub con-

nector kits and cables

• Mass interconnect solutions

Ethernet connectivity enables simple

connection to the network and remote

I/O throughput, or take advantage of

the remote capabilities and distribute

troubleshoot, or debug your application

remotely. Ethernet communication also

can be used with the support of LAN

sockets connections.

The optional GPIB interface has many

years of proven reliability and can be

used for easy integration into existing

instruments. This makes it easy to

configure and integrate instruments

into your system.

Fully-featured graphical web

interface makes it easy to set-up and

troubleshoot your tests from anywhere

remote access and control of the

instrument via a Java-enabled browser

such as Internet Explorer. Using the

• Define and output waveforms

• View error queue

• Get status reports, current configura-

tion, firmware revisions, and more

Additionally, since the web interface

is built into the instrument, you can

access it on any operating system

that supports a web browser without

having to install any special software.

Password protection and LAN lockout

environments ensures compatibility and

efficiency. You can use direct I/O with

your own software, or use standard

IVI and LabVIEW software drivers that

provide compatibility with the most

popular development environments:

• Agilent T&M Toolkit for Microsoft

Visual Studio.NET and Agilent VEE

• National Instruments LabVIEW,

LabWindows/CVI, TestStand, and

Switch Manager

• Microsoft C/C++ and Visual Basic
