Abstract

The utility model provides a SATA signal testing anchor clamps of measurationing, its structure includes that M. 2 direct a matching await measuring the port and draw forth the M. 2 SATA interface of the SATA signal that awaits measuring, do you and connect the M. 2 SMA of SATA interface SMA signal cable, M. 2SATA interface connection, is there SMA SMA signal cable SMA does SMA signal cable pass through TCA SMAAdapter or TCA 292MMAdapter connects the outside oscilloscope who is used for testing the SATA signal. The utility model discloses in, M. 2 the signal line of SATA interface is drawn with the mode of SMA interface, and the connection of convenient test avoids hand moving point to survey at test procedure, can eliminate the error that the operation brought, improves signal measuration precision and efficiency of software testing, is favorable to M. 2 SATA TX signal integrality's test.

Description

One kind measures SATA signal testing fixtures

Technical field

The utility model is related to a kind of test fixture, specifically a kind of to measure SATA signal testing fixtures.

Background technology

M.2 it is that Intel leads the lower interface standard of new generation formulated and release, that is, the NGFF (Next for frequently referring to Generation Form Factor), it is less with volume, interface faster the characteristics of.

M.2 the interface of SATA passages supports flank speed SATA Gen3 (6Gbit/s), and is based on onboard M.2 interface SATA integrity tests, in the condition of the M.2 TX signals for not possessing direct testing SA TA passage, directly putting survey using probe can Be able to can run into cannot normally touch the unstable situation of signal pins or contact.

For these reasons, a kind of measurement SATA signal testing fixtures are designed, it is intended to be applied to the SATA signals of M.2 interface Integrity test.

The content of the invention

Technical assignment of the present utility model is to solve the deficiencies in the prior art, for being inconvenient to use probe measurement M.2 to connect The problem of the SATA signal integrities of mouth, there is provided one kind measures SATA signal testing fixtures.

The technical solution of the utility model is realized in the following manner：

One kind measures SATA signal testing fixtures, and the test fixture directly matches M.2 port to be measured and draws including one M.2 the SATA interface of SATA signals to be measured, and the SMA-SMA signal cables of connection M.2 SATA interface, M.2 SATA interface The outside oscillograph of testing SA TA signal is connected to by SMA-SMA signal cables.M.2 M.2 SATA interface extraction is to be measured holds The SATA signals to be measured of mouth, and the outside oscillograph for testing SA TA signal is transferred to by SMA-SMA signal cables, pass through Oscillograph realizes the waveform crawl of SATA signals to be measured and uniformity test.

On the basis of said structure, involved SMA-SMA signal cables pass through TCA-SMA Adapter or TCA- 292MM Adapter are connected to the outside oscillograph of testing SA TA signal, and the waveform for further realizing SATA signals to be measured is grabbed Take and uniformity test.

On the basis of said structure, the number of involved SMA-SMA signal cables is four.

A kind of measurement SATA signal testings fixture of the present utility model beneficial effect produced compared with prior art is：

The utility model is reasonable in design, simple structure, and M.2 the holding wire of SATA interface is drawn in the way of SMA interfaces, The connection of convenient test, avoids point manually from surveying in test process, can eliminate the error that operation brings, improve measuring signal precision and Testing efficiency, is conducive to the test of M.2 SATA TX signal integrities.

Description of the drawings

Accompanying drawing 1 is attachment structure figure of the present utility model.

Mark in accompanying drawing is represented respectively：

1st, M.2 SATA interface, 2, SMA-SMA signal cables, 3, TCA-SMA Adapter,

4th, TCA-292MM Adapter, 5, outside oscillograph.

Specific embodiment

Below in conjunction with the accompanying drawings 1, a kind of SATA signal testing fixtures that measure of the present utility model are described in detail below.

As shown in Figure 1, a kind of measurement SATA signal testing fixtures of the present utility model, the test fixture includes one directly Connect matching M.2 port to be measured and draw M.2 SATA interface 1 of SATA signals to be measured, and connect M.2 SATA interface 1 four Bar SMA-SMA signal cables 2.

M.2 SATA interface 1 is connected with four SMA-SMA signal cables 2, and above-mentioned four SMA-SMA signal cables 2 pass through TCA-SMA Adapter 3 or TCA-292MM Adapter 4 are connected to the outside oscillograph 5 of testing SA TA signal.

M.2 SATA interface 1 draws the SATA signals to be measured of M.2 port to be measured, and is transmitted by SMA-SMA signal cables 2 To the outside oscillograph 5 for being used for testing SA TA signal, waveform crawl and the uniformity of SATA signals to be measured are realized by oscillograph Test.

For attachment structure of the present utility model, need to add is that, M.2 the holding wire of SATA interface 1 with The mode of SMA interfaces is drawn, the connection of convenient test, avoids point manually from surveying in test process, can eliminate the error that operation brings, Measuring signal precision and testing efficiency are improved, is conducive to the test of M.2 SATA TX signal integrities.

In description of the present utility model, need to add is that, unless otherwise clearly defined and limited, term " connected " should be interpreted broadly, and for the ordinary skill in the art, with concrete condition above-mentioned term can be understood at this Concrete meaning in utility model.

In sum, above content is only illustrating the technical solution of the utility model, rather than the utility model is protected The restriction of scope, although the specific embodiment part has been made to explain to the utility model, the ordinary skill of this area Personnel should be appreciated that can modify or equivalent to the technical solution of the utility model, new without deviating from this practicality The spirit and scope of type technical scheme.
