Keysight / Agilent / HP 82350B PCI GPIB Interface

The Keysight/Agilent/HP 82350B is a PCI GPIB interface card that enables direct control of IEEE 488 instruments from desktop and laptop computers equipped with standard PCI slots. The card decouples GPIB transfers from PCI bus operations using built-in buffering, delivering superior I/O and system performance compared to Direct Memory Access (DMA) architectures. It connects up to 14 GPIB instruments in daisy-chain configuration and supports data transfer rates up to 900 KB/s.

## Technical Specifications

• **Interface:** PCI GPIB (IEEE 488.1 and IEEE 488.2) with 24-pin IEEE-488 connector
• **PCI Compatibility:** 5V, 32-bit PCI slot (rev 2.1, rev 2.2); not compatible with 3.3V PCI, EISA, or ISA
• **Data Transfer Rate:** Up to 900 KB/s
• **Instrument Capacity:** 14 GPIB instruments (daisy-chain)
• **Hardware:** Xilinx XC2S100 FPGA; Texas Instruments SN75160/SN75162 bus buffers
• **Configuration:** Plug-and-play; software configurable

## Key Features

• Built-in buffering minimizes transaction overhead
