Abstract
An electronic circuit tester for measuring the response of electrical signals applied to an electronic circuit under test is provided with a calibration board for effecting calibration of the tester to the plane of connectors incorporated into a test head of the tester. The calibration board includes a dielectric substrate, calibration standards, such as opens, shorts, and loads, mounted to the substrate in respective regions of the substrate, connectors for electrically connecting the calibration standards to the connectors of the test head when the calibration board is selectively substituted for a fixture board, structure for mounting the calibration board to the test head so that electrical connection is established between the calibration board and the test head, and indicia on the calibration board and the test head for indicating a sequence of rotational positions of the calibration board for calibration of the tester using the calibration standards. The calibration board is sequentially rotated to the indicated rotational positions so that the tester can be calibrated to the plane of the connectors of the test head. The calibration board can further include at least one ver…
