The Keysight/Agilent/HP E1301A is a B-size VXI mainframe with 9 slots—7 external B-size and 2 internal B-size slots plus 3 external A-size slots—designed to integrate VXI instrumentation for automated test equipment and data acquisition systems. The built-in command module provides GPIB (IEEE 488.1) and RS-232 control interfaces, while the front-panel keyboard and two-line vacuum fluorescent display enable local operation and troubleshooting independent of external controllers. Power delivery reaches 120 W maximum at 40°C across multiple rails: +5 Vdc @ 12.2 A, +12 Vdc @ 4.6 A, and -12 Vdc @ 0.9 A. All outputs are protected against over-temperature, over-voltage, over-current, and short-to-ground faults.
