Abstract:

A signal generator of the radio compass antenna based on DDS chip AD9959 is designed to realize the situ measurement of the radio compass.The output signal of the generator can be controlled by program.And the relations of frequency,amplitude and phase for the output signal accord with the characteristics of the radio compass antenna output signal,which can meet the requirements of radio compass function test,performance test and fault isolation for antenna signals.The signal generator can be integrated into the ATE to implement automatic testing of the radio compass.
