On-chip virtual network analyzer, method, computer device, and storage medium

A method for on-chip virtual network analyzing, comprising:

• providing an equalizer of an on-chip virtual network analyzer, wherein, the equalizer is deployed at a receiver end of a first channel, the equalizer is configured for modulating an intermediate signal according to an adjustable equalization gain so as to obtain an output signal, the intermediate signal is obtained by transmission of an input signal through the first channel;
• providing a peak detector of the on-chip virtual network analyzer, wherein, the peak detector is deployed at the receiver end, the peak detector is configured for detecting a waveform peak of the output signal;
• wherein, the on-chip virtual network analyzer is configured for establishing a loss model of the first channel in a training mode, the loss model of the first channel indicates losses of a plurality of signals of different frequencies with a fixed amplitude transmitted through the first channel respectively, and, the equalizer in the training mode does not modulate,
• the on-chip virtual network analyzer is configured for, in an operating mode, in accordance with the loss model of the first channel, based on a frequency of the input signal and the waveform peak of the output signal detected by the peak detector, adjusting the adjustable equalization gain, such that an amplitude of the output signal is consistent with an amplitude of the input signal,
• wherein the peak detector in the training mode is configured for providing a frequency sweep function for determining a S21 parameter of a system including the first channel and the on-chip virtual network analyzer, the S21 parameter being a gain-to-bandwidth change curve.
