Abstract:
1. A signal generating device comprising: a display; a central processing unit generating a user interface on the display for setting parameters for a victim signal and an aggressor signal wherein a waveform record file of the victim signal is generated using the victim signal parameters and a waveform record file of the aggressor signal is generated using the aggressor signal parameters; an S-parameter conversion circuit receiving at least a first S-parameter array representative of characteristics of a multiple-port signal channel and generating filter coefficients for a first filter representing near end crosstalk, a second filter representing far end crosstalk and a third filter representing a transfer characteristic between a first port and a second port; a crosstalk emulation circuit receiving the waveform record of the victim signal, the waveform record of the aggressor signal and the filter coefficient for the first, second and third filter and generating a waveform record file representative of the victim signal with emulated crosstalk effects wherein the waveform record file of the aggressor signal is separately filtered by the first filter and the second filter with the filtered waveform record file using the first filter being summed with the waveform record file of the victim signal and the resultant summed waveform record file being filtered by the third filter and summed with the filtered waveform record using the second filter to generate a waveform record file of the victim signal with emulated crosstalk effects; and a waveform generation circuit receiving the waveform record file of the victim signal with emulated crosstalk effects and generating an analog output signal representative of the victim signal with emulated crosstalk effects.
