Condition: Used

The Keysight Agilent L4451A is a 4-channel isolated D/A converter that is LXI compliant, featuring built-in Ethernet connectivity and a fully-featured graphical web interface. Each of the four isolated analog output channels can be updated individually at a 200 kHz update rate, outputting up to ±16V DC or ±20mA DC with 16-bit resolution. Onboard memory supports custom waveforms of over 500,000 points, which can be dynamically allocated among one or more channels and output as a point-to-point arbitrary waveform. Standard waveforms are also provided. Ideal for sourcing bias voltages, controlling analog programmable power supplies, or providing setpoints for control systems. The unit connects via a standard 50-pin D-sub connector, compatible with standard cables, terminal blocks, or mass interconnect solutions. This listing includes the 34951T 4-channel DAC accessory.
