Keysight / Agilent / HP E2071D / 82341D HPIB Card

The Keysight/Agilent/HP E2071D/82341D HPIB card is an ISA/EISA slot interface enabling computer control of HP-IB, GPIB, and IEEE-488 instruments. It bridges host computers to laboratory and industrial test equipment, supporting up to 14 instruments per bus with data rates reaching 750 KB/s write and 580 KB/s read performance.

## Technical Specifications

**Data Transfer Performance**
• Maximum data rate: 750 KB/s
• Controller read rate: 580 KB/s
• Controller write rate: 750 KB/s
• Transaction start-up time: 0.3 ms
• Maximum instruments per bus: 14

**Host Interface**
• Slot type: ISA/EISA
• Protocol standards: IEEE 488.1/488.2
• Primary bus: HP-IB/GPIB/IEEE-488

**Software Support**
• I/O libraries: SICL, VISA
• Operating systems: HP-UX 10.20, Windows 95, Windows NT, Windows 10 (64-bit), Windows 11 (64-bit)
• Programming languages: HP VEE, C/C++, BASIC

## Key Features

• Built-in buffering for enhanced I/O performance
• Automatic handshaking protocols
• Programmable interrupt capability
• Intel Plug-and-Play support (82341D)
• Hardware EOI line detection

## Typical Applications

Automated test environments, instrument control networks, laboratory data acquisition systems, and industrial measurement configurations requiring parallel multi-device communication.

## Compatibility & Integration

The E2071D/82341D interfaces with 82341C, 85123A, 89075C, E2910A, E4840A, E4849A, E8431A, G2030A, and Z5200FB instruments. Agilent 82341 boards may require firmware upload via gpib_config with the “–init-data” option following power-up. The 82341 detects end-of-string through EOI line assertion only; REOS flag usage during reads may reduce maximum transfer rates. DIP switch configuration for I/O address and interrupt assignment may be necessary depending on operating system and system configuration. MS ChemStation G1701BA version B.02.00 (Windows NT 4.0 SP6a) provides the most recent full HP-IB compatibility.
