Calibration device for microwave analysis equipment or microwave measurement equipment

摘要

An apparatus for calibration of an electronic instrument, such as a vector network analyzer, includes a number of calibrator connector elements for connection to the instrument, and a plate element including a plurality of calibration waveguide structures. The plate element has conductive surfaces, and the calibrator connector elements and conductive surfaces include periodic structures disposed with respect to each other such that gaps are formed between them. An interface enables interconnection of a waveguide of a calibrator connector element, a waveguide of the instrument, and a calibration waveguide structure. The apparatus includes a driving unit and controller for moving the plate element and/or the calibrator connector element to connect the calibrator connector element to different calibration waveguide structures.
