The HP 8153A may be operated in environments with humidity up
to 95% (O°C to +40°C). The HP 8153A should be protected from
temperatures or temperature changes that cause condensation within
the instrument.
The HP 8153A has a cooling fan mounted internally. Mount or
position the instrument so that air can circulate through it freely.
When operating the HP 8153A, choose a location that provides at
least 75mm (3inches) of clearance at the rear, and at least 25mm
(linch) of clearance at each side. Failure to provide adequate air
clearance may result in excessive internal temperature, reducing
instrument reliability.
A maximum of 15V can be applied as an external voltage to any of
the BNC connectors.
The instrument can be stored or shipped at temperatures between
-40°C and +70°C. The instrument should be protected from
temperature extremes that may cause condensation within it.
