Agilent L4452A Multifunction with Digital I/O, D/A, Totalizer Data Sheet * LXI compliance includes built-in Ethernet connectivity * Fully-featured graphical Web interface * 32-bits of digital I/O up to 42 V * 100 kHz gated totalizer * Two 12 V analog outputs with 1 mV of resolution * Software drivers for most common programming environments 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. 2 Figure 1. L4452A Multifunction Digital I/O, D/A, totalizer 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 Figure 2. The Web interface makes it easy to set up, troubleshoot and maintain your test remotely 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 3 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(R).NET and Agilent VEE Pro * National Instruments LabVIEW, LabWindows/CVI, TestStand, and Switch Manager * Microsoft C/C++(R) and Visual Basic(R) Multifunction instrument wherever your application needs it Power button Status LEDs Easy connection options with terminal blocks, standard 50-pin cables or connector kits Optional GPIB External trigger to synchronize events 4 Built-in Ethernet Product Specifications Specifications and Characteristics Digital input/output characteristics Four 8-bits channels, 8 bits wide, input or output, non-isolated Vin(L) < 0.8 V (TTL) Vin(H) > 2.0 V (TTL) Vout(L) < 0.8 V @ Iout = -400 mA Vout(H) > 2.4 V @ Iout = 1 mA Vin(H) max < 42 V with external open drain pull-up Alarm Maskable pattern match or state change Speed 4 ms (max) alarm sampling Latency Read/write speed 95/s Max count 2 26 - 1 Totalize input 100 kHz (max) rising or falling edge, programmable Signal level 1 Vp-p (min) 42 Vpk (max) Threshold 0 V or TTL Gate input TTL-Hi, TTL-Lo, or none Totalize input characteristics Count reset Manual or read + reset Read speed 85 rdgs/s DAC 1, 2 12 V, non-isolated Resolution 1 mV IOUT 10 mA max Settling time 1 ms to 0.01% of output Accuracy (% of output + mV) 1 year (0.25% + 20 mV) Temp. coefficient (0.015% + 1 mV)/C Analog output characteristics 5 Product Specifications (continued) Data out of memory to LAN or GPIB (data transfer rate with 1000 channel blocks) GPIB LAN (w/ VXI 11) rds/s rds/s Readings 2560 3542 readings with timestamp 1304 readings with all format options ON 980 1826 1361 Scan triggering Source Interval, external, software, or on monitor channel alarm Scan count 1 to 50,000 or continuous Scan interval 0 to 99 hours; 1 ms step size Channel delay 0 to 60 seconds per channel; 1 ms step size External trig delay <2 ms.
