A chassis shielding effectiveness evaluation system includes a chassis having a chassis ground. A board is located in the chassis and includes a board ground layer. A signal generator includes at least one ground member coupled to the chassis ground and a signal member coupled to the board ground layer. The signal generator is operable to send a signal through the signal member to the board ground layer.

Chassis shielding effectiveness evaluation system

A system for operating a data storage device having a plurality of sectors and at least one port, each port having a transmitter and a receiver, is disclosed. In one embodiment the system includes coupling at least one of the transmitters to at least one of the receivers, providing power to the data storage device, detecting that the transmitter is coupled to the receiver, and executing code for exercising the data storage device.

Standalone data storage device electromagnetic interference test setup and procedure

A data storage device includes a plurality of sectors and a port, the port having a transmitter and a receiver. In one embodiment a method includes coupling the transmitter to receiver, providing power to the data storage device, detecting that the transmitter is coupled to the receiver, and executing code for exercising the data storage device.

A retention device for computer expansion cards, a system including the device, a method of manufacture of the device, and a method of using the device, where the retention device includes a retention clip configured to engage the bracket of the expansion card to reduce flex and rotation of an expansion card when the expansion card and the retention device are installed in an expansion card bay of a computer system, and wherein the retention clip is configured to contact the proximal end of the expansion card.

Expansion card retention device and methods thereof

EMI from an operating information handling system is managed by disposing a stirring device in the chassis of the information handling system to mechanically modulate the resonance of predetermined RF signals emitted from processing components within the chassis. For example, a cooling fan disposed in the chassis has a reflective surface formed on its blades so that rotation of the blades mechanically modulates the RF signals. The blades have a depth of at least one-quarter of the wavelength of the RF signal and are coated with a low resistance material, such as steel, aluminum, copper, carbon loaded plastic or a high dielectric ceramic. The fan rotates at the faster of the speed required to provide desired cooling or the speed desired to produce a desired average RF signal amplitude.

System and method for managing information handling system electromagnetic interference

An information handling system has a printed circuit board with a split power plane having a plurality of sections that may be used for distributing different voltages on a single conductive foil layer of the printed circuit board to components on the printed circuit board. Capacitive coupling of the split power plane sections may be enhanced with a high dielectric fill between the portions.
