Abstract
Systems and methods are provided for common mode testing for a system using an Ethernet subsystem. The Ethernet subsystem generates test signals that can be introduced at various points in the system to detect the effect of noise introduced by various elements of the system. By introducing test signals at various points in a system, common mode noise introduced into the system can be more accurately determined.
Claims20
A system, comprising:
- a first transceiver, coupled to a first transformer, configured to generate a first test signal to be applied to a center tap of the first transformer;
- and
- a first controller, coupled to the first transformer, configured to:
- receive a first output signal generated by the first transformer, and
- analyze the first output signal to determine a first amount of noise introduced into the first test signal by the first transformer.
2 more elements
A system, comprising:
- a first magnetic element;
- a first transceiver coupled to the first magnetic element, wherein the first transceiver is configured to:
- generate a first test signal,
- receive a first output signal generated by the first magnetic element, and
- analyze the first output signal to determine a first amount of noise introduced into the first test signal by the first magnetic element.
2 more elements
A method for detecting noise introduced into a system, the method comprising:
- generating, at a first transceiver, a first test signal;
- receiving, at an output of a first magnetic element, a first output signal;
- and
- analyzing the first output signal to determine a first amount of noise introduced into the first test signal by the first magnetic element.
