Apparatus and Method for Generating a Waveform Test Signal Having Crest Factor Emulation of Random Jitter

A signal generating device comprising:

• a display;
• a central processing unit generating a user interface on the display for setting parameters for a serial data pattern and parameters for deterministic jitter impairments, random jitter impairments, and at least one displacement crest factor emulation impairment to be applied to the serial data pattern, wherein a waveform record file is generated using the serial data pattern parameters, and the serial data pattern impairment parameters for the deterministic jitter, random jitter, and the displacement crest factor emulation impairment with the displacement crest factor emulation impairment being selectively positioned in the impaired serial data pattern;
• and
• a waveform generation circuit receiving the waveform record file and generating an impaired serial data pattern analog output signal based on the serial data pattern parameters and the parameters for deterministic jitter impairments, random jitter impairments, and at least one displacement crest factor emulation impairment with the displacement crest factor emulation impairment being selectively positioned in the impaired serial data pattern analog output signal.
