| Abstract: | A SPORT port of DSP is used to control a 16 bit-serial high speed DAC ,and an arbitrary wave- form signal generator is designed and used to control VCO of a Ka-band CW radar to generate wave whose frequency can be modulated at will. The generator is used to measure the tuning characteristic and the step response of the VCO with the help of a modulation domain analyzer. |

| Keywords: | continuous wave radar DSP DAC modulation domain |
