Abstract
A tool plate for oscilloscope calibration disclosed comprises a communication interface, a control circuit, a change over switch circuit, a standard signal input interface and more than two standard signal output interfaces. The tool plate has more than two standard signal output interfaces, each of which is connected with an oscilloscope to be calibrated. One standard source can be used for calibrating a plurality of oscilloscopes. When calibration is started, the change over switch circuit on the tool plate automatically switches the oscilloscope to be calibrated, and a computer automatically determines and records calibration results without human monitoring, which substantially improves production efficiency and reduces manpower resource. Less manual operation prevents man-made faults and improves the reliability of the calibration results.
