Abstract
A transistor test fixture for conducting reference and data measurements on transistors comprises rotatable disc means having short circuit means, through circuit means and data circuit means provided thereon. The rotatable disc means is positionable within a disc-receiving area of housing means having spaced coaxial means to provide signal input and output to the circuit means, and retaining and positioning means are provided by the rotatable disc means and the housing means to retain the disc means in the disc receiving area and to position the rotatable disc means in selected positions with the selected circuit means being in electrical connection with the coaxial means.
Claims8
A transistor test fixture for testing transistor means, comprising:
- housing means having a disc-receiving area;
- coaxial connector means provided by said housing means adjacent said disc-receiving area;
- disc means having reference circuit means and data circuit means thereon, said disc means positionable within said disc-receiving area;
- retaining means provided by said housing means and said disc means for retaining said disc means within said disc-receiving area and to permit said disc means to be removed therefrom;
- and
- maintaining means provided by said disc means and said housing means for maintaining said disc means in a selected position so that said reference circuit means or said data circuit means is electrically connected to said coaxial connector means.
A transistor test fixture for testing transistor means, comprising:
- housing means having a disc-receiving area;
- transmission line means provided by said housing means including outer and inner coaxial connector means connected thereto, said inner coaxial connector means being positioned adjacent said disc-receiving area;
- disc means positionable within said disc-receiving area and including through circuit means, short circuit means and transistor circuit means with which leads of the transistor means are to be engaged;
- retaining means provided by said housing means and said disc means for retaining said disc means within said disc-receiving area and to permit said disc means to be removed therefrom;
- maintaining means provided by said housing means and said disc means for maintaining said disc means in one of selected positions so that one of said through circuit means, short circuit means and transistor circuit means is electrically connected to said inner coaxial connector means;
- and
- hold-down means provided by said housing means for holding the leads of the transistor means in electrical engagement with said transistor circuit means when said transistor circuit means is electrically connected to said inner coaxial connector means.
