1-12 Keysight Self-Configured System Installation GuideSafety and Regulatory InformationEnvironmental Requirements1-Environmental RequirementsThe environmental requirements shown below are characteristic for the systemand are based on the limitations of the PNA network analyzer used.System Heating and CoolingInstall air conditioning and heating, if necessary, to maintain the ambienttemperature within the appropriate range (as given in the table above). Airconditioning capacity must be consistent with the BTU ratings given in Table1-2 on page 1-12 and Table 1-3 on page 1-12.Ventilation Requirements: When installing the product in a cabinet, theconvection into and out of the product must not be restricted. The ambienttemperature (outside the cabinet) must be less than the maximumoperating temperature of the instrument by 4 °C for every 100 wattsdissipated in the cabinet. If the total power dissipated in the cabinet isgreater than 800 watts, then forced convection must be used.Table 1-2 Millimeter-wave System Environmental Conditions (Operating)Environment TemperatureOperation 0 ° C to 40 °C (41 ° F to 104 °F)Storage –40 °C to +65 °C (–40 °F to 158 °F)Measurement Calibration 20 °C to 26 °C (68 °F to 79 °F)Performance Verification Temperature must be within 1 °C (1.8 °F) ofthe temperature at which the measurementcalibration was performed.Relative Humidity Type tested at 95%, +40 °C (non-condensing)Pressure Altitude Type tested 0 to 4600 meters (~15,000 feet)Table 1-3 N5292/3/5A Environmental Conditions (Operating)Environment Temperaturefor indoor use only (unless specified otherwise.) 0 °C to 40 °CAltitude up to 4,600 metersTemperature 0 to 40 °CRelative humidity Type tested, 0 to 95% relative humidity,non-condensing up to 40°C
