Signal generator is a common source of the signal, widely used in electronic circuits, automatic control and scientific experiments, and other fields. It is a measurement of electronic measurement and work to meet stringent technical requirements of the signal equipment. Therefore, signal generators and oscilloscopes, voltage meter, such as the frequency of the same equipment is the most common and most basic is the most extensive application of electronic devices, almost all the parameters, the measurement will need to use signal generator.
Direct Digital Synthesis techniques DDS is the next generation of frequency synthesis technology, using digital control signals in the incremental phase, with high frequency resolution and fast switching frequency, frequency switching phase for phase noise and low As well as digital and easy to integrate the advantages that are widely used.
The system design of a sine wave generator, using the company's 16 Sunplus SCM SPCE061A, because of their low power consumption, ultra-small, low-cost, full-featured, very applicable to portable instrumentation and control instruments showed that the spot-in China has received increasing attention and users of a wide range of applications. SPCE061A SCM powerful, eight-way chip containing 10 A / D converter and two D / A converters, the waveform generators use SCM technology, through clever software design and simple hardware circuit, a The digital sine wave. Signal frequency, through the keyboard input, and display. And various types of existing waveform generator comparison, the small number of signal interference, output stability, high reliability, in particular the operation of simple, friendly interface and low cost, very suitable for teaching and experimental physics laboratory use.
