Abstract: As the telemetry parameters and the data formats of satellite communication are various, the different signal sources are needed to satisfy the requests of tests for different satellites. Considering the cost factor, the telemetry parameters and data formats for programmable satellite signal source are needed.The system compositions and the working principle of this kind of satellite signal source are introduced. The PSK realization modulation and the white Gauss noise production modulation,key parts of the system,are analyzed and discussed also.The former one uses digital method including direct digital frequency synthesis, the latter one uses the combination of Lagged-Fibonacci arithmetic and formula method. The test results indicate that this kind of programmable satellite signal source can satisfy most satellites’test requirements.

Key words: telemetering, signal source, PSK modulation, white noise, Gauss
