Abstract: Provided are a sampling circuit and a sampling method. The circuit comprises: a generator, configured to generate a first loopback pulse signal; a loopback selection module, configured to establish a plurality of loopback links according to a pre-configured connection combination; a link loopback pulse signal transmission module, configured to receive the first loopback pulse signal, and transmit the first loopback pulse signal in the plurality of loopback links; a loopback sampling module, connected to the link loopback pulse signal transmission module and configured to determine, from the plurality of loopback links, a target loopback link on which sampling is to be performed, and sample first link data that is on the target loopback link and passes through a target sampling point, and a sampling storage module, connected to the loopback sampling module and configured to store sampling data in a random access memory.

Abstract: The present disclosure provides a delay ripple detection method and a delay ripple detection circuit. The method includes: generating a pulse signal corresponding to a transmission link to be monitored; aligning and transmitting the pulse signal corresponding to the transmission link and data corresponding to the transmission link in the transmission link; and monitoring the pulse signal after being transmitted in the transmission link, and determining whether a delay ripple anomaly is present in the transmission link according to the monitored pulse signal.
