It can meet many of the requirements of the test system, and has bee an integral part of system test. Besides, with technology advanceshas, the signal generator as a general experimental source has played a pivotal role in today39。s electronic experimental design. 1 Introduction signal is a generator with the longest measuring instruments, as early as the 1920s when the emerging electronic equipment it has. As the munications and radar technology development, 40 in a major test for a variety of standard receiver signal generator so that the signal generator from the qualitative analysis of the test equipment developed into a quantitative analysis of the measuring instruments. At the same time there also can be used to measure pulse circuit or pulse modulator for the pulse the early signal generator mechanical structure more plicated, more power, the circuit is relatively simple, relatively slow pace of development. Until 1964 there was the first alltransistor signal generator. Since the 1960s, since the signal generator with the rapid development of a function generator, this period of analog signal generator use of electronic technology, by discrete ponents or analog integrated circuits constituted, the circuit structure plicated and can only have a sine Wave, square wave, sawtooth and triangle wave, and so few simple wave, because the analog circuit drift higher, to the extent of output waveform poor stability, but also pose a simulator of the circuit there is a large size,
