RADIO COMMUNICATION DEVICE COMPRISING TWO RECEPTION SYSTEMS AND RECEPTION STATE DISPLAY FUNCTION, AND RECEPTION STATE DISPLAY METHOD IN RADIO COMMUNICATION DEVICE COMPRISING TWO RECEPTION SYSTEMS

摘要

PROBLEM TO BE SOLVED: To provide a radio communication device comprising two reception systems and a reception state display function that makes it easy to keep track of a reception state at a sub-band with a reception frequency band different from an operation frequency band of a main band while communicating with another station in the main band without increasing manufacturing costs.SOLUTION: A radio communication device changes a scan frequency band of a radio signal received in a sub band at constant intervals or arbitrary time intervals, displays a spectrum scope image 23 of the strength of a radio signal in a first frequency range centered around an operation frequency in a main band on part of the display screen of a two-dimensional display device 2, and displays a spectrum scope image 24 of the strength of a radio signal in a second frequency range in a scan frequency band in a sub band on other part of the display screen.SELECTED DRAWING: Figure 2
