R3I31 Spectrum Analyzer Operation Manual
1.3 Operating Environment
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 Series 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 Series 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
unavoidable.
• An area allowing unobstructed air flow
The R3131 Series 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
measurement accuracy.
• Avoid operation in the following areas. • Use a noise cut filter when there is a large
amount of noise riding on the power line.
