1.3 Operating Environment
This section describes the environmental conditions and power requirements necessary to use the spectrum
analyzer.
1.3.1 Environmental Conditions
The R3131 should be only be used in an area which satisfies the following conditions:
• Ambient temperature: 0°C to +50°C (operating temperature)
• Relative humidity: 85% or less (without condensation)
• An area free from corrosive gas
• An area away from direct sunlight
• A dust-free area
• An area free from vibrations
• A low noise area
Although the R3131 has been designed to withstand a certain amount of noise riding on the AC
power line, it should be used in an area of low noise. Use a noise cut filter when ambient noise is una-
voidable.
• An area allowing unobstructed air flow
The R3131 has an exhaust cooling fan on the rear panel and an exhaust vent on the bottom side
toward the front. Never block these areas as the resulting internal temperature rise will affect meas-
urement accuracy.
