Grounding the QX Hawk
Proper grounding is necessary for operator safety, noise reduction, and the protection of
equipment from voltage transients. Buildings, including any steelwork, all circuits, and all
junction boxes must be grounded directly to an earth ground in compliance with local and
national electrical codes.
QX Hawk
An earth ground is provided through the cable shields and chassis of the imager.
Ground Loops
Ground loops (signal degradation due to different ground potentials in communicating
devices) can be eliminated or minimized by ensuring that both the host, imager, and their
power supplies are connected to a common earth ground.
