Keysight / Agilent / HP E6235A VXI Pentium PC Controller

The Keysight/Agilent/HP E6235A is a C-size, 2-slot VXI Pentium PC controller that embeds a standard PC environment directly within VXI mainframe architectures. It eliminates the need for external command modules by providing integrated computer access to VXI devices, system memory, and trigger signals. The controller features a 32-bit wide VXIbus data path and delivers full peripheral connectivity for test system integration.

## Technical Specifications

• **Processor:** Intel Pentium, 200 MHz
• **Memory:** 16 MB to 128 MB RAM
• **Storage:** 1 GB to 10 GB hard drive; 1.44 MB floppy drive
• **Data Path:** 32-bit wide VXIbus access
• **Form Factor:** C-size, 2-slot module

## Key Features

• Direct VXIbus integration via 32-bit data path eliminates external controller dependency
• Standard PC architecture supports Windows NT and VXIplug&play-compliant software
• Comprehensive I/O: PS/2 keyboard and mouse, serial (COM), USB, Ethernet, VGA monitor, SCSI, and parallel (LPT) ports
• HP-22/EXM-22 GPIB card typically installed for instrumentation control
• Single additional EXM slot allows custom interface expansion
• Integrated 1.44 MB floppy drive for legacy boot and data transfer

## Compatibility & Integration

• Compatible with E84XX, E1401B, and E1421B VXI mainframe series
• Supports SICL/VISA and VXIplug&play standards for instrument driver integration
• Native Windows NT environment simplifies software deployment and maintenance
• VXIbus architecture enables seamless communication with other C-size and 1/3-size modules within the same chassis

The E6235A consolidates controller, processor, and connectivity into a single VXI module, reducing system footprint while maintaining full access to mainframe resources and external instrumentation networks.
