Keysight/Agilent E1421B C-Size VXI Mainframe
The E1421B C-Size VXI Mainframe from Keysight/Agilent works as a VXI-bus unit. It accommodates six C-size VXI modules within a space-efficient enclosure. Its compact architecture supports installations where equipment density and available workspace remain critical considerations. The chassis supports portable deployment and rack-mounted integration without requiring structural modifications. The unit complies with VXIbus Specification Revision 1.4 for complete bus compatibility. The data transfer functions operate according to established VXI bus standards for dependable communication performance. The unit incorporates P1 and P2 connectors for proper module interfacing requirements. The nominal operating frequency range extends from 50 Hz to 60 Hz with ±10 percent tolerance. The power supply of the E1421B also supports 400 Hz input operation for specialized installations. Under 400 Hz operation the nominal voltage range remains 100 V AC to 120 V AC.
The VXI Mainframe features an ultra-reliable power supply for continuous operation. The power subsystem supports automatic voltage ranging across nominal input levels. Input voltage ranges from 100 V AC to 240 V AC with ±10% tolerance. The maximum inrush current reaches 40 A during startup conditions and power initialization. Service access remains simplified through a rear-panel power supply maintenance arrangement. The maintenance personnel can access power components while minimizing equipment downtime. The arrangement supports streamlined service operations within controlled technical environments. The cooling system utilizes a pressurized air channel design for thermal management and supports effective heat dissipation across installed VXI modules during operation. Available cooling capacity provides 60 W per slot at a 10°C temperature rise.
The protective circuitry of the Keysight/Agilent E1421B safeguards all outputs against several electrical fault conditions. Protection mechanisms address over-temperature events that could affect component reliability. The short-to-ground protection further enhances operational security and electrical system integrity. The unit provides substantial current resources for installed instrumentation. The +5 V supply delivers 45.00 A peak current capacity. Dynamic current capability on the +5 V rail reaches 5.00 A. The unit includes additional power resources with a +12 V output rated at 8.00 A peak. These rails provide 2.50 A dynamic current capability when required. The negative supply rail operates at –12 V with 8.00 A peak current.
