Abstract

Disclosed are a SAS signal integrity analysis system and a method. The system runs in a master computer, which is connected with an electronic product to be measured and an oscilloscope. The system comprises a parameter setting module, a signal measurement module and a signal analysis module. According to the method, a SAS signal can be acquired through a SAS interface of the electronic product; SAS signal integrity parameters are measured by the utilization of the oscilloscope; and a parameter corresponding to the SAS signal with optimum signal integrity is analyzed according to the SAS signal integrity parameters so as to find out a drive parameter which best fits the SAS interface.

Description

technical field [0001] The invention relates to a signal analysis system and method, in particular to a SAS signal integrity analysis system and method. Background technique [0002] Currently, serial interfaces (Serial Attached SCSI, SAS interfaces) are the main storage interfaces widely used by enterprises in the market. In order to ensure the integrity of the SATA-TX signal generated by the SATA hard disk, it is necessary to set the parameters of the driver IC of the SATA hard disk. Therefore, it is necessary to measure the SATA-TX signal generated by different types of SATA hard disks and make corresponding settings and adjustments. At present, manual measurement and setting operations are performed manually, and then suitable measurement parameters are selected according to the test results. The test is cumbersome and time-consuming, and the accuracy of the test results is not high. Contents of the invention [0003] In view of the above, it is necessary to provide a...
