  • Apparatus and method for varying inter symbol interference and bandwidth extension pre-emphasis on a high speed digital signal
    Patent number: 8705601
    Abstract: A signal generating device has a display, central processing unit and a waveform generating circuit. The central processing unit generates a user interface on the display for setting parameters for a serial data pattern and a parameter for an intersymbol interference and a bandwidth extension pre-emphasis effect on the serial data pattern. A waveform record file is generated using the serial data pattern parameters and the intersymbol interference effect and bandwidth extension pre-emphasis effect parameter. A waveform generation circuit receives the waveform record file and generates a serial data pattern analog output signal having the intersymbol interference effect or the bandwidth extension pre-emphasis effects defined by the intersymbol interference and bandwidth extension pre-emphasis effect parameter.
