ザ。[Scope of Claim for Utility Model Registration] (1) A character generator that receives character display data including display position information and character information and generates a character pattern signal corresponding to this character display data while superimposing it on a video signal. , a signal level detection section for each band that inputs an audio signal and detects the signal level for each band, a character storage section for spectrum analysis display that stores one type of character used for spectrum analysis display, and one type of character used for spectrum analysis display. a selection operation section for performing a selection operation; a registration section for registering characters selected by the selection operation section in a character storage section for spectrum analyzer display; and a registration section for registering each band with one type of character registered in the character storage section for spectrum analyzer display. a spectrum analyzer display control section that uses the above to create character display data for displaying a spectrum analyzer with a number of character strings corresponding to the band-specific signal level detected by the band-specific signal level detection section, and outputs it to the character generator; A spectrum analyzer characterized by the following. (2) The spectrum analyzer display character storage section stores one type of character for each band, the selection operation section selects one type of character for each band, and the registration section stores characters selected by the selection operation section. is registered in the spectrum analyzer display character storage section for each band, and the spectrum analyzer display control section detects each band by the band-specific signal level detection section using the characters for each band registered in the spectrum analyzer display character storage section. 2. The spectrum analyzer according to claim 1, wherein character display data for displaying a spectrum analyzer is created using a number of character strings corresponding to the signal level of each band, and is output to a character generator. (3) The spectrum analyzer display character storage section stores one type of character for each band and level position, the selection operation section performs a selection operation for one type of character for each band and level position, and the registration section stores one type of character for each band and level position. The characters selected in are registered in the spectrum analyzer display character storage section by band and level position, and the spectrum analyzer display control section registers each band using the characters according to the band and level position registered in the spectrum analyzer display character storage section. Therefore, character display data for displaying a spectrum analyzer with a number of character strings corresponding to the band-specific signal level detected by the band-specific signal level detection section is created, and the character display data is output to the character generator. The spectrum analyzer according to claim 1.
