Environmental Requirements
Environmental Requirements
The environmental requirements shown below are characteristic for the system
and are based on the limitations of the PNA network analyzer used.
Ventilation Requirements: When installing the product in a cabinet, the
convection into and out of the product must not be restricted. The ambient
temperature (outside the cabinet) must be less than the maximum
operating temperature of the instrument by 4 °C for every 100 watts
dissipated in the cabinet. If the total power dissipated in the cabinet is
greater than 800 watts, then forced convection must be used
.
Samples of this product have been type-tested in accordance with the
Keysight Environmental Test Manual and verified to be robust against the
environmental stresses of storage, transportation and end-use; those
stresses include but are not limited to temperature, humidity, shock,
vibration, altitude, and power-line conditions. Test methods are aligned
with IEC 60068-2 and levels are similar to MIL-PRF-28800F Class 3.
