This unit
The Keysight L4451A is a 4-channel isolated digital-to-analog converter engineered for precision signal generation and control in test systems. This LXI Class C compliant instrument delivers DC voltage outputs to ±16 V and DC current outputs to ±20 mA across four independent isolated channels, each with 16-bit resolution and 200 kHz update rates. Built-in Ethernet connectivity and a graphical web interface enable remote operation and straightforward system integration without requiring additional hardware modules.
