Agilent/Keysight E6234A

The Keysight E6234A is a VXI Pentium PC Controller that functions as an embedded processor within VXIbus systems, eliminating the need for external command modules. This C-size, 2-slot module integrates directly into compatible mainframes, providing full computational control and direct access to VXI devices, system memory, and trigger signals. The controller operates at 166 MHz and features a full 32-bit wide data path (D32) on the VXIbus, enabling message-based communication with instrumentation.
