Agilent / Keysight E1328A 4-Channel D/A Converter

The Agilent/Keysight E1328A is a 4-channel D/A converter module designed for precision analog signal generation within VXI modular test systems. This B-size, 1-slot VXI instrument provides four independent, isolated digital-to-analog converter channels, each with 16-bit resolution and configurable output modes for DC voltage or DC current applications. Each channel floats independently up to 350 Vdc from ground, enabling flexible system control, automation, and signal conditioning across diverse measurement and test environments.
