Embodiment Construction

[0027] Such as figure 1 Shown is a structure diagram of a preferred embodiment of the signal integrity testing system 10 of the hard disk interface 20 of the present invention. The hard disk interface 20 may be a SAS interface (Serial Attached SCSI, called a serial connection interface), or a SATA interface (Serial Advanced Technology Attachment, called a serial drive interface). In the present embodiment, the signal integrity testing system 10 is installed and operated in the main control computer 1, the main control computer 1 is connected with the electronic product 2 through the COM port, and the general-purpose interface bus (General-Purpose Interface) Bus, GPIB interface) is connected with the oscilloscope 3. The electronic product 2 is a motherboard or a computing device including a plurality of hard disk interfaces 20, such as a personal computer, a server, and the like.

[0028] The main control computer 1 is connected with a mechanical arm 4, and the mechanical arm...

Abstract

Disclosed are a system and a method for testing signal integrity of hard disk interfaces. The system runs in a main control computer which is connected with an oscilloscope and a mechanical arm, and the mechanical arm is provided with a testing jig. The hard disk interfaces include an SAS (serial attached SCSI) interface and an SATA (serial advanced technology attachment) interface. The system comprises a parameter setting module, an arm control module, a signal measuring module, a signal analysis module and a report generation module. The system controls the mechanical arm to move the testing jig to each hard disk interface to acquire transmission signals, utilizes the oscilloscope to measure and analyze signal integrity parameters corresponding to the transmission signals with excellent signal integrity, and accordingly find out parameter set value for driving of each hard disk interface. By combination of the mechanical arm and the testing jig, the SAS interface and the SATA interface are switched automatically to complete testing, and thus, operation hours is shortened for personnel and error can be avoided.

Description

technical field [0001] The invention relates to a signal measuring system and method, in particular to a signal integrity testing system and method of a hard disk interface. Background technique [0002] Due to the development of cloud systems, the storage capacity and data security requirements of hard disks are constantly increasing. At present, the storage interface used by enterprises is mainly serial connection port (Serial Attached SCSI, hard disk interface). In order to ensure the signal integrity of the transmission signal of the SATA hard disk (commonly known as SAS-TX signal), it is necessary to perform a signal integrity test for each hard disk interface during product development. Since a storage system usually has dozens of hard disks, it takes a lot of time, equipment and human resources to do the test. [0003] At the present stage, the repetitive insertion and extraction actions are performed manually for measurement, and then the oscilloscope is manually op...
