Advantest R4131D
Spectrum Analyzer 10KHz to 3.5GHz
Description
The R4131D covers a bandwidth as wide as 10kHz to 3500 kHz and is controlled by a microcomputer. This analyzer features easy confirmation of all measuring conditions.
The panel of the R4131D enables its three major functions to be independent of each other, and its layout makes for excellent operability. In addition, the resolution band, sweep time and input attenuator values are set automatically by its AUTO feature.
Refrain from using the R4131D equipment in a place subject to much vibration or direct sunlight and where corrosive gas is generated. This unit is designed for indoor use.
Also, do not use the R4131D where the ambient temperature is outside 0 to 50 deg C and relative humidity is less than 85%.
Since the R4131D equipment employs a suction type cooling fan to prevent the internal temperature from rising, install this equipment 10 cm or more from the wall, and do not place anything close to its back nor use this equipment in an incorrect position.
Although the equipment is designed to compensate for noise from the AC power supply line, use it where there is low noise as much as possible and use a noise filter for noisy places.
