Voice Frequency Sweep-frequency Signal Generator
CRY5520 - Hangzhou JiGao Electroacoustical Science and Technology Co.,Ltd (CRY Sound Co., Ltd.)
CRY5520 Voice Frequency Sweep-frequency Signal Generator adopts a single-chip microcomputer to control sweep frequency. Digital and simulation is combined to have stable performance. It has very low distortion and is applicable for sound inspection of loudspeaker and earphone. It can operate in logarithm sweep frequency and manual frequency adjustment modes. Starting point, end point and time of sweep frequency can be set at will. Manual frequency adjustment is divided into rough adjustment and fine adjustment to accurately and rapidly adjust frequency. 12864 dot matrix liquid crystal display is adopted to display frequency and voltage value.
