摘要： A signal generator generates amplitude noise on a selected segment of a test signal. A user interface is used for selecting a segment of the test signal and an associated power level for applying amplitude noise at a selected power level to the test signal segment. A signal processing unit compiles the selected power level of the selected segment with the test signal to generate digital data representative of the test signal with selected segments having amplitude noise. A waveform generator receives the digital data and generating a test signal output having amplitude noise at selected segments of the test signal. The method includes the steps of: selecting a segment of the test signal to add amplitude noise; selecting a power level for the amplitude noise; and applying the amplitude noise at the selected power level to the selected segment of the test signal.

摘要： A signal generator generates a WiMedia ultra wideband test signal with a user interface for setting test sequences and parameters of the test signal. Parameters are set for Presentation Protocol Data Units associated with Packet Groups of the test signal. A signal processing unit compiles the Groups containing the Presentation Protocol Data units to generate digital data representative of the test signal. A waveform generator receives the digital data and generating a test signal output having Packet Groups containing Presentation Protocol Data Units. A method is describes for setting test sequences and parameters of an ultra wideband test signal test signal with a user interface of the signal generator.
