Abstract

The invention provides a Slimline interface SATA signal test fixture and test method. The test fixture is composed of a Slimline male head, two pairs of PCB wires and two pairs of SMA male heads. TheSlimline male head connects the test fixture and the tested interface. The PCB wires lead the signal to the SMA male head interface from the Slimline interface. The SMA male head is connected with anoscilloscope through an SMA cable. According to the test fixture, the Slimline interface SATA signal test can be conveniently performed and connection with the oscilloscope through the SMA cable can be realized so that operation is flexible and convenient, the test efficiency can be enhanced, the measurement error caused by direct spot measurement through the probe can be eliminated and the test accuracy can be enhanced.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a SATA signal testing fixture and testing method of a Slimline interface. Background technique [0002] With the continuous improvement of board density, the packaging size of components is getting smaller and smaller, and Slimline is being used more and more widely as a high-density, small-size connector. The signal pins of the Slimline interface have a high density and are all wrapped, and the SATA signal of the Slimline interface is a high-speed signal, which must be tested for signal integrity. If you use the probe to test directly on the Slimline interface, you may encounter the situation that the signal pin cannot be contacted normally or the contact is unstable, resulting in the failure to perform normal and accurate testing. [0003] For the SATA signal integrity test of the Slimline interface, if you do not use a test fixture, you can only use a high-speed probe to dire...
