Cooling Considerations
NOTE The Agilent 70843 12.5 Gb/s BERT will operate within the specified
temperature range (see page 4-2) but optimum performance is obtained
close to 25
o
C ambient temperature. During use, it is important to make
sure there is no obstruction to airflow through the instrument. Cooling
air is taken in on the right-hand side and is blown out through the left-
hand side of the instrument, looking from the front. If this airflow is
obstructed the performance and reliability of the instrument will be
reduced. In the rack-mounted system, it is particularly important to
make sure the airflow is not obstructed. For example, cables in the side
of the racks can obstruct the airflow. Also, make sure the input air
temperature is not increased above the specified temperature range by
other instruments in the rack. If forced ventilation is used in a rack the
air pressure on both sides of the instrument must be the same for the
instrument cooling to operate correctly.
