| Abstract: | This Paper puts forward a design scheme depending on microprocessor for frequency scan sinagl impetus resource,which has been used on freguency character test for disk driver's machinery and circurit system.This impetus resource adopts two-grade frequency devision scheme,so it can. give out arbitrary waveform frequeney scan signal within a wide frequency range,providing a good frequency change gradient.It is an ideal scan signal resource in low frequency. At the end of this paper,the test result is given |
