– Key Features
Thermal Management
Keysight Pressurized Air Channel cooling technology maintains optimal operating temperatures across the mainframe.
Serviceability
Power supply and fan modules are accessible via the rear panel with a Mean Time To Repair of 5 minutes. Field service involves replacement of power supply module, backplane module, or mechanical components only.
– Compatibility & Integration
Full compliance with VXIbus Specification Revision 1.4 and VXIplug&play Specification enables straightforward integration into existing VXI instrumentation systems. The mainframe accepts standard C-size modules and, with the E1403 Module Carrier, hosts A and B size instruments.
