The Keysight/Agilent/HP E1418A is a C-size VXI module that delivers 8 channels of precision digital-to-analog conversion for high-performance signal generation and data acquisition. Option 002 provides full galvanic isolation across all eight channels, with each channel individually isolated to 42 Vdc/ac peak. This register-based module integrates into VXIbus systems and supports both voltage and current output modes, local and remote sensing, and programmable output disconnect relays per channel.
