Claim 14:
15. The device for determining the PCIe signal bandwidth according to claim 13, wherein obtaining, by testing, the target frequency point at which the energy spectrum density of the output signal, after being subjected to inverse Fourier transform, of the PCIe signal corresponding to the PCIe signal type passing the target analog transmission link reaches the preset proportion of the original signal of the PCIe signal type comprises:
obtaining, by testing, the target frequency point at which the energy spectrum density of the output signal, after being subjected to inverse Fourier transform, of the PCIe signal corresponding to the PCIe signal type firstly being synthesized to be an interference signal by a synthesizer and then passing the target analog transmission link reaches the preset proportion of the original signal of the PCIe signal type.
