METHOD, DEVICE AND SYSTEM FOR MEASURING SIGNAL LINK

摘要

The present invention provides a method, device and system for measuring a signal link, wherein the method includes: inputting a periodicity measurement signal into a signal link to be measured; accumulating the first measurement signal outputted from the signal link to be measured and obtaining an accumulation signal, and the first measurement signal is a signal outputted by transmitting a signal composed of at least the periodicity measurement signal through the signal link to be measured; executing a computation according to the periodicity measurement signal and the accumulation signal, and obtaining the link parameters of the signal link. The present invention also provides a corresponding device for measuring the signal link and a system, which includes the above device, for measuring the signal link. The method, device and system provided by the present invention enable to perform the online measurement of a signal link.
