Systems and methods for measurement of electrical channel loss

摘要

In accordance with embodiments of the present disclosure, a method for characterizing electrical characteristics of a communication channel between a transmitter of a first information handling resource and a receiver of a second information handling resource may include receiving a test signal at the receiver from the transmitter during an in-situ characterization mode of the second information handling resource, converting the test signal into a discrete-time digital signal representing the test signal, generating a discrete-time finite difference function comprising a first derivative of the discrete-time digital signal, transforming the discrete-time finite difference function into a frequency-domain transform of the discrete-time finite difference function.

1. An information handling system comprising:
a processor; a first information handling resource communicatively coupled to the processor; a second information handling resource communicatively coupled to the processor and the first information handling resource, the second information handling resource having a receiver configured to:
during an in-situ characterization mode of the second information handling resource, receive a test signal from a transmitter of the first information handling system resource;convert the test signal into a discrete-time digital signal representing the test signal; andgenerate a discrete-time finite difference function comprising a first derivative with respect to time of the discrete-time digital signal; and a baseboard management controller communicatively coupled to the second information handling resource and configured to transform the discrete-time finite difference function into a frequency-domain transform of the discrete-time finite difference function.
