4-Channel Isolated D/A Converter with Memory Data Sheet
4-Channel D/A Converter offers high-voltage analog outputs wherever your application needs it The Keysight Technologies, Inc. L4451A is a high-performance 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 Keysight L4451A has four isolated analog channels that are useful to source bias voltages to your device under test, to control your analog programmable power supplies, or use the outputs as setpoints for your control systems. You can use the standard waveforms provided or create your own with over 500,000 points. These points can be dynamically allocated among one or more channels and output as a point-to-point arb. Using this LXI instrument, you’ll get all the benefits of an Ethernet connection, built-in instrument web interface, standard software drivers and more. The LXI standard is supported by multiple vendors, en - abling lower cost of test with accelerated test integration and development. – LXI compliance includes built-in Ethernet connectivity – Fully-featured graphical web interface – Four isolated analog outputs – Outputs up to ±16 V or ±20 mA DC – 16-bits of resolution – 200 kHz update rate – Default standard waveforms – Software drivers for most common programming environments Introduction
