1. Field of the Invention
The present invention generally relates to an interface device for product testing and, more particularly, to an interface device for product testing that shortens the operation time for product testing and enhances the flexibility so as to shorten the activation time of the product during testing and to augment the application range of the product.
2. Description of the Prior Art
The objects, spirits and advantages of the preferred embodiment of the present invention will be readily understood by the accompanying drawings and detailed descriptions, wherein:
FIG. 1 is a block diagram schematically illustrating a conventional product testing system in accordance with the prior art; and
FIG. 2 is a block diagram schematically illustrating a product testing system in accordance with one preferred embodiment of the present invention.
The present invention providing an interface device for product testing can be exemplified by the preferred embodiment as described hereinafter.
To start with, please refer to FIG. 2, which is a block diagram schematically illustrating a product testing system in accordance with one preferred embodiment of the present invention. As shown in the figure, the interface device 30 according to the present invention comprises: a 1394 PHY (physical layer) 34; a protocol transform device 32 and a plurality of interconnecting devices 36 of various transmission interface specifications. The 1394 PHY 34 is connected to a computer 20 through an interconnection line 38. The plurality of interconnecting devices 36 are provided for connecting to devices under testing (DUT's) 40 of various transmission interface specifications, respectively. The protocol transform device 32 is connected to the 1394 PHY 34 and the plurality of interconnecting devices 36, such that a protocol signal of IEEE 1394 interface is transformed into a protocol signal of various transmission interface specifications.
In order to test a DUT 40, the computer 20 has to support IEEE 1394 interface so that the testing software 22 generates a testing signal transmitted through a 1394 controller 24 and a 1394 PHY 26 to the interface device 30 of the present invention. After the 1394 PHY 34 of the interface device 30 receives the signal, the protocol transform device 32 transforms the signal into a protocol signal of the transmission interface for the DUT 40, and then an interconnecting device corresponding to the transmission interface transmits the signal to the DUT 40.
