The equipment is a portable type spectrum analyzer suited for signal analysis of radio equipment where the efficiency of frequency usage is increased and equipment is increasingly speeded and digitized. The equipment adopts the synthesizer local system and can cover all frequencies from 1kHz to 3.0 GHz excellent in basic performance such as distortion, frequency/level accuracy, and easy operation, by following the display of the soft-key menu screen. Excellent cost performance with rich options to cope with various applications. Equipped with high accuracy calibration signals and an attenuator, it can accurately calibrate switching errors of LOG/LIN scales, resolution bandwidth, reference level, etc. Since frequency response data is corrected by built in calibration data, allowing high- accuracy level measurement for a wide range. This unit provides the MEASURE function that can perform measurement of various applications without requiring the intervention of external controllers. Therefore, the performance evaluation of radio equipment can be easily done in terms of frequency, noise, occupied frequency bandwidth, etc. Application This unit is useful for the production, building and maintenance of electronic equipment and devices for the following. AM/FM radio equipment Digital cellular telephone/cordless telephone Satellite broadcasting and TV equipment Small capacity microwave equipment
