The invention relates to a calibration adapter with a coaxial connector (10), in particular a coaxial plug or coaxial socket or coaxial coupler, for connecting to a coaxial connector of a device to be calibrated, in particular to a measurement port of a vectorial network analyzer (VNA), wherein the coaxial connector (10) has an inner conductor part (12), an outer conductor part (14) arranged coaxially thereto, and a male termination (16) that can be connected to the coaxial connector of the device to be calibrated. According to the invention, the calibration adapter has a drum (26) in which at least two calibration standards (38, 40, 42, 44) are arranged, wherein said drum (26) is rotatably arranged on a pin (32) which is connected centrally to a first cap (22) in such a way that a longitudinal axis of the pin (32) is flush with a longitudinal axis of the first cap (22), wherein the coaxial connector (10), with a second termination (18) opposite to the male termination (16), is connected to the first cap (22) excentrically to the longitudinal axis of the first cap (22), and the calibration standards (38, 40, 42, 44) are arranged in the drum (26) in such a way that by the rotation of the drum (26) relative to the first cap (22), the second termination (18) opposite to the male termination (16) of the coaxial connector (10) can be optionally connected to one of the calibration standards (38, 40, 42, 44). |
