N5280A
General Specifications
Environmental Requirements
The environmental requirements of the Test Set are listed in
the N5242A PNA-X and N5264A Measurement Receiver standard
documentation for environmental requirements.
Ventilation Requirements: When installing the instrument in a cabinet, the
convection into and out of the instrument 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, forced convection must be used.

The N5280A complies with all applicable safety and regulatory requirements
for the intended location of use.
— The instrument can safely operate in a relative humidity of 80% for
Equipment Heating and Cooling
If necessary, install air conditioning and heating to maintain the ambient
temperature within the appropriate range. Air conditioning capacity must be
consistent with the BTU ratings given in
Required Conditions for Accuracy Enhanced Measurement
Accuracy–enhanced (error–corrected) measurements require the ambient
temperature of the PNA and Test Set to be maintained within ± 1 °C of the
ambient temperature at calibration.
