ABSTRACT
In modern electronics in all areas, the waveform generator is that often requires high accuracy and adjustable frequency , the use of Generator are less popularization than Multimeter and oscilloscopes. Now the waveform generator can produce more higher the frequency waveforms, and more type than before, but the costs of device and technical requirements have risen consumedly.
In high accuracy experiments ,it can use SCM transmitted data ,and through calculating amplifier ,turn out triangular wave sine wave and square wave ,etc.The wave form is explicit ,with good frequency adjustment and stability performance. It only by varying its software ,not hardware ,if we need obtain more complicated wave form.
The features, pin description，inner block diagram and application circuit of MAX038 was Introduced in this article. Had given take MAX038 as the core signal generating device complete electric circuit, and the design ideas and involved issues were discussed. With compare of other types the waveform generator, that system had the advantage that SCM and MAX038 to core components of the hardware circuit had very high function price a ratio and can do a small size.
Keywords: Max038 ; SCM ; waveform generator
