Keysight / Agilent / HP E2078A PCI GPIB Interface for HP-UX 10.20 Workstations

The E2078A is a PCI GPIB interface card designed for HP-UX 10.20 workstations, providing IEEE-488.1 and IEEE-488.2 connectivity for instrument control and data acquisition. The card installs into 5-volt PCI slots and delivers data transfer rates up to 750 KB/s with built-in buffering that exceeds traditional DMA performance. Auto-configurable via PCI standards, it requires no manual switch settings for installation. The E2078A supports SICL/VISA software libraries and programming in Agilent VEE, C/C++, and BASIC/UX, making it suitable for both standalone workstation applications and VXI mainframe integration via GPIB connection to Slot 0 command modules.

## Technical Specifications

• **Standard:** IEEE-488.1 and IEEE-488.2
