Instrument Positioning and Cooling
Mount or position the instrument upright and horizontally so that
air can circulate around it freely. When operating the E5574A,
choose a location that provides at least 75mm (3 inches) of
clearance at the rear, and at least 25mm (1 inch) of clearance at
each side. Failure to provide adequate air clearance may result in
excessive internal temperature, reducing instrument reliability.
