Multifunction instrument offers your system control functionality wherever your application needs it

The Agilent L4452A is a multifunction instrument that is

LXI Class C compliant. With its small size and Ethernet connectivity, this multifunction instrument can be placed wherever your application needs it.

The Agilent L4452A allows great flexibility for a variety of sense and control applications.

It combines four 8-bit channels of digital input and output, a

100 kHz gated totalizer, and two ±12 V analog outputs all on a single earth-referenced module.

Using this LXI instrument, you’ll get all the benefits of an

Ethernet connection, instrument

Web server, standard software drivers and more. The LXI standard is supported by multiple vendors, enabling lower cost of test with accelerated test integration and development.

Digital I/O, D/A converter and totalizer for your most common test requirements

The L4452A combines digital

I/O, analog outputs and a gated totalizer for your most common system control needs.

The digital I/O supports output levels up to 42 V. These channels can be used with an external power supply to control external devices or to sense limit switch and digital bus status with no complex handshake modes.

You can use the totalizer input to count events. The digital inputs and totalizer inputs may be included in a scan. Alarm limits for the digital and event counter inputs are evaluated continuously, capturing and logging alarm conditions even between scans.

The analog outputs can output up to ±12 V or 10 mA DC with

1 mV of resolution. They can be used to source bias voltages to your device under test, to control your analog programmable power supplies, or use the outputs as set points for your control systems.

External trigger capabilities make it easy for you to time and synchronize measurements and other events. This can help you determine when to begin or end a scan.

System connections you can trust

The L4452A comes with one heavy duty 50-pin Dsub connector that allows for simple, reliable connection options. Each connector uses

30 micro-inches of gold to ensure a repeatable, accurate measurement. Flexible connection options include:

• Detachable terminal blocks with strain relief

• Low-cost, standard 50-pin

Dsub connector kits and cables

• Mass interconnect solutions

Ethernet connectivity enables simple connection to the network and remote access to measurements

The Ethernet interface offers high-speed connections that allow for remote access and control. You can set up a private network to filter out unwanted

LAN traffic and speed up the I/O throughput, or take advantage of the remote capabilities and distribute your tests worldwide.

Monitor, 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 applications.

The L4452A ships with the

Agilent E2094N I/O Libraries

Suite making it easy for you to configure and integrate instruments into your system — even if your system includes instruments from multiple vendors.

Fully-featured graphical Web interface makes it easy to set-up and troubleshoot your tests from anywhere in the world

The built-in Web browser interface provides remote access and control of the instrument via a Java-enabled browser such as Internet Explorer.

Using the Web interface, you can set up, troubleshoot, and maintain your instrument from remote locations.

• View and modify instrument setup

• Configure I/O channels, analog outputs, totalizer and alarms

• Read and write I/O channels

• Output analog channels

• View error queue

• Get status reports, current configuration, firmware revisions, and more

Additionally, since the Web server is built into the instrument, you can access it on any operating system that supports the Web browser without having to install any special software.

Password protection and LAN lockout are also provided to limit access for additional security.

Software for most popular programming environments

Full support for standard programming environments ensures compatibility and efficiency. You can use direct

I/O with the software you already have and know, or use standard IVI and LabVIEW TM software drivers that provide compatibility with the most popular development environments:

• Agilent T&M Toolkit for

Microsoft Visual Studio®.NET

and Agilent VEE Pro

• National Instruments

LabVIEW, LabWindows/CVI,

TestStand, and Switch

Manager

• Microsoft C/C++® and

Visual Basic®
