With its small size and Ethernet connectivity, the Digital I/O can be placed wherever your application needs it. The Agilent L4450A has 64 bi-directional lines configured as eight 8-bit channels. Each 8-bit channel has programmable polarity and thresholds up to 5 V. The 128 k of memory is useful for simulating and capturing digital patterns up to 10 MHz. The configurable handshaking protocols can be used for a wide variety of applications. In addition, the two counter channels can be used to count events, frequency, period, duty cycle, pulse width and totalize. 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 inputs and outputs for your most complicated digital applications The L4450A can be used to simulate or detect digital patterns. It has eight 8-bit digital I/O channels with handshaking, pattern memory, two 10 MHz counters with gate functions, and a programmable clock output. Digital input/output The digital I/O bits are organized into two banks of 32-bits. The I/O bits can be configured and programmed as inputs or outputs in 8-bit channels. The digital outputs can be configured as active drive or open drain outputs with a user supplied 10 k pull up. User supplied pull-up resistors for up to 5 V outputs are also acceptable. The digital inputs have programmable thresholds up to 5 V for compatibility with most digital logic standards. The on-board pattern memory can be used to select and output digital stimulus or bit stream patterns, or to capture external digital data. Each bank has independent memory and directional control so that one bank can output data while another captures data. The memory can be divided up to 64 kbytes per 8-bit channel. The memory can be allocated as follows: Default Configuration Memory on Channels 1 & 2 Memory on Channel 1 Channel 1/5 (Bits 7:0) (Bits 39:32) 32 kbytes 64 kbytes 64 kbytes Channel 2/6 (Bits 15:8) (Bits 47:40) 32 kbytes 64 kbytes Channel 3/7 (Bits 23:16) (Bits 55:48) 32 kbytes Channel 4/8 (Bits 31:24) (Bits 63:56) 32 kbytes The digital channels also have: * Internal alarming for maskable pattern match * Variable active high drive output from 1.65 V to 5 V or open drain * 1 hardware pattern interrupt per bank * Variable input thresholds from 0 V to 5 V * Configurable handshaking protocols including synchronous and strobe * Programmable polarity * Source or sink up to 24 mA 2 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 an acquisition. Frequency counter and totalizer The two channels can be used to count digital events, frequency, period, duty cycle, pulse width and totalize. The counter/totalizer also includes: * Programmable gate functionality * Programmable input thresholds levels 0 V to 3 V System connections you can trust The L4450A comes with 2 heavy duty 78-pin Dsub connectors that allow 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 78-pin Dsub connector kits and cables * Mass interconnect solutions Figure 1. L4450A 64-bit digital I/O with counter 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. 3 The optional GPIB interface has many years of proven reliability and can be used for easy integration into existing applications. The L4450A 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, patterns and alarms * Read and write I/O channels * Load and step digital patterns * Define handshaking and memory allocation * 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 Figure 2. The Web interface makes it easy to set up, troubleshoot and maintain your test remotely 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 4 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) High-performance digital I/O wherever your application needs it Power button Status LEDs Easy connection options with terminal blocks, standard 78-pin cables or connector kits Optional GPIB External trigger to synchronize events 5 Built-in Ethernet Product Specifications Specifications and Characteristics Digital input/output characteristics Eight 8-bit channels: 8 bits wide, input or output, non-isolated Vin 0 V - 5 V1 Vout 1.65 V - 5 V 1,2 Iout (max) 24 mA2 Frequency (max) 10 MHz3 ILoad (max) 400 mA tr + tf (typ) 6 ns5 Vin 0 - 5 V4 Vout 1.65 - 5 V 2,4 I out (max) 24 mA2 Frequency (max) 10 MHz Maximum freq 10 MHz (max) 50% duty cycle Vin 0V-5V Maximum count 2^32 - 1 (4,294,967,296) Handshake lines Counter function characteristics Totalizer function characteristics Max input freq 10 MHz (max), rising or falling edge programmable Vin 0V-5V Gate input 0V-5V Frequency 20 MHz - 10 Hz configurable divide-by-n 24-bits, programmable on/off Vout 1.65 V - 5 V 2 Accuracy 100 ppm System clock generator characteristics 1 Configurable by 8-bit channel Lower current drive at lower voltages From memory with handshaking 4 Configurable by bank 5 5 V, 50 pF load 2 3 6 Product Specifications (continued) Data out of memory to LAN or GPIB (data transfer rate with 1000 channel blocks) GPIB rds/s LAN (w/ VXI 11) rds/s Readings 2560 3542 readings with timestamp 1304 1826 readings with all format options ON 980 1361 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.
