Agilent/Keysight E1401T

The Agilent/Keysight E1401T is a C-size, 13-slot VXI mainframe for constructing modular test and measurement systems. It has a high-density platform with a VXI backplane, power distribution, and integrated cooling for housing up to 13 C-size VXI modules. The E1401T delivers high peak and dynamic current capabilities, making it suitable for power-intensive instrumentation applications while maintaining compliance with VXI Specification and VXIplug&play standards.
