Abstract:
1. A test fixture for an oscilloscope probe, the test fixture comprising: a carrier having first and second ends separated by an intervening region; a first RF connector disposed upon the first end of the carrier; a dielectric substrate disposed upon the intervening region of the carrier and having at least one metallic surface upon which is patterned a transmission line having at least first and second conductors; a first conductor of the first RF connector connected to the first conductor of the transmission line and a second conductor of the first RF connector connected to the second conductor of the transmission line; an axle disposed above the dielectric substrate such that the dielectric substrate is between the axle and the intervening region of the carrier, and also such that the axle is parallel to the metallic surface upon which is patterned the transmission line and generally at a right angle to an axis of one of the conductors of the transmission line; first and second levers each having a bore therethrough and through which the axle passes to carry those levers, each lever having a foot portion on one side of its bore and a handle portion on the other; the first and second levers being positioned such that rotation of one of the levers about the axle brings its foot portion into contact with the first conductor of the transmission line and that rotation of the other of the levers about the axle brings its foot portion into contact with the second conductor of the transmission line; and first and second springs, respectively disposed between the first and second levers and the carrier, the first and second springs urging the foot portions of the first and second levers against the dielectric substrate.
