Agilent/Keysight E6237A

The Agilent/Keysight E6237A is a C-size, 2-slot VXI controller module that is a real-time, message-based system controller for VXI mainframe integration. It has direct computer access to VXI devices, system memory, and triggers without requiring a separate command module. The E6237A features a full 32-bit wide data path (D32) on the VXIbus for maximum throughput and includes one EXM expansion slot for optional interface cards.

Technical Specifications

Processor & Memory

Key Features

• Message-based, real-time controller architecture eliminates dedicated command module requirement


• Single EXM expansion slot enables custom interface integration


• Standard LAN connection provides flexible system connectivity


• Supports Agilent SICL I/O library and C-SCPI instrument command language


• Memory upgradeable using standard SODIMM modules

Storage Considerations The 2.16 GB internal drive is configured for low-usage operation. Continuous disk read/writes exceeding once per minute may cause premature failure. High-frequency storage applications require external SCSI hard drives or VXI disk modules such as the E3249B.

Compatibility & Integration The E6237A integrates with all Agilent C-size mainframe chassis. Dual optional licensing packages support both development (Option 001) and run-time environments (Option 002), enabling flexible deployment in production and development workflows.
