Agilent / Keysight E1301A HP 75000 Series B with front panel

The Agilent/Keysight E1301A is a B-size VXI mainframe from the HP 75000 Series, purpose-built as a standalone test platform for VXI-based measurement systems. Unlike its counterpart the HP E1300A, the E1301A includes an integrated front panel with keyboard and vacuum fluorescent display, enabling local operation, troubleshooting, and data monitoring without external controller dependency. This makes it ideal for remote installations and field applications where HP-IB connectivity may be limited.

Technical Specifications

• Form Factor: B-size VXI mainframe


• Slot Configuration: 9 total slots (7 external, 2 internal); accommodates three A-size and up to seven B-size VXI modules externally


• Command Module: Built-in command module, functionally equivalent to HP E1306A


• Local Control: Front panel keyboard and vacuum fluorescent display for menu navigation, measurement results, and instrument status


• Interface: HP-IB (IEEE-488) for external controller communication; built-in RS-232 port for terminal, printer, or device connection


• Trigger I/O: Rear-panel trigger input and pacer output BNC connectors


• Programmability: SCPI (Standard Commands for Programmable Instruments); optional HP IBASIC for standalone operation


• Power Supply: Generates backplane logic signals ACFAIL* and SYSRESET* per VXI Specification Revision 1.4; optional DC power connector for portable or UPS applications


• Cooling: Standard cooling; dual-fan option available for demanding module loads

Key Features

• Full VXI Specification compliance (Revision 1.4) with VXIplug&play support


• Integrated controller eliminates external system requirements


• Standalone measurement capability via local keyboard interface


• Optional 3.5-inch ruggedized floppy drive (Option 005) for program and data storage


• EMC compliant per Directive FTZ 1046/84

Compatibility & Integration The E1301A accepts standard VXI modules and integrates directly with HP-IB peripherals, printers, and measurement instruments. Two internal slots can house B-size modules; one slot reserves space for the controller PCA. Optional multimeter modules (E1326A/E1326B) occupy the remaining internal capacity.
