E5500 Phase Noise Measurement System Version A.02.00
Ground the instrument
To minimize shock hazard, the
instrument chassis and cover
must be connected to an
electrical protective earth
ground. The instrument must be
connected to the ac power mains
through a grounded power cable,
with the ground wire firmly
connected to an electrical
ground (safety ground) at the
power outlet. Any interruption
of the protective (grounding)
conductor or disconnection of
the protective earth terminal
will cause a potential shock
hazard that could result in
personal injury.
