摘要： A signal generating device has a display and a central processing unit for setting parameters for a serial data pattern and parameters for deterministic and random jitter impairments, and a displacement crest factor emulation impairment to be applied to the serial data pattern. A waveform record file is generated using the serial data pattern parameters, the impairment parameters for the deterministic jitter and random jitter, and the displacement crest factor emulation impairment. The displacement crest factor emulation impairment is selectively positioned in the impaired serial data pattern. A waveform generation circuit receives the waveform record file and generates an impaired serial data pattern analog output signal based on the serial data pattern, deterministic and random jitter impairments, and the displacement crest factor emulation impairment with the displacement crest factor emulation impairment being selectively positioned in the impaired serial data pattern analog output signal.

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.
