摘要
Abstract
The design of signal generator using MAX038 as a core chip and controlled by single chip AT89S51 to realize adjustment of frequency and amplitude is introduced. The realization of frequency control is to convert the digital quantity of sin⁃gle chip into analog quantity through DAC0832. The realization of amplitude control is to control the sliding⁃end position of digi⁃tal potentiometer X9C103 by single chip after the signal is amplified by operational amplifier OPA604. The output waveform type,frequency,amplitude and amplitude step value are set by 4 × 4 keyboard. The real⁃time display of every set value is achieved by LCD1602A. The testing result indicates that the system runs stable and its effect is better.关键词
