Agilent/Keysight E8402A

The Agilent/Keysight E8402A is a C-size VXI mainframe that is the interface between modular VXI instruments and controlling computers. This 13-slot mainframe delivers medium power output and enhanced monitoring capabilities for instrument management, diagnostics, and system health tracking.

Technical Specifications

• Form Factor: C-Size VXI Mainframe


• Slot Configuration: 13 slots


• Power Output: Medium Power


• Backplane: Surface mount design with improved reliability and stripline signal performance; generates SYSRESET and ACFAIL signals for full VXI Specification compliance


• Cooling System: Variable-speed fans with innovative air distribution and dedicated power supply cooling for thermal management


• Specifications Compliance: VXIbus Specification Revision 1.4, VXIplug&play Specification VPP-8, VMEbus System Specification Revision C.1

Key Features

• Enhanced monitoring of backplane voltage conditions, slot temperatures, power supply temperatures, and fan status


• History queue and strip charts/histograms for system diagnostics


• Injector surface rails for easy module insertion and extraction per VXI Specification (QUIC system)


• Rear-panel access to power supply and cooling components for in-rack maintenance


• Plug-in power supply design enables field replacement without mainframe removal


• Quiet, efficient variable-speed fan operation

Typical Applications The E8402A supports modular instrument configurations in automated test systems, laboratory environments, and production facilities requiring VXI-based instrument control and data acquisition.

Compatibility & Integration Designed to house VXI modules and operate with VXI controllers and interface modules supporting the VXIbus standard. Operates with VXIplug&play drivers and compatible with controller solutions such as the Keysight E8491B IEEE 1394 PC Link to VXI. User and Service Manual (Part Number E8402-90002) covers both E8402A and E8404A mainframe operation and service procedures.
