Problems solved by technology

However, especially in calibration references in the form of short-circuited precision air passages, it is a potential source of error when the short-circuit connection between the inner and outer conductors is not made precisely
Therefore, in the known "short-circuit" type of calibration references, the connection is designed to be fixed and non-detachable

Embodiment Construction

[0030] exist Figure 1 to Figure 4 Illustrate in - according to the present invention as the coaxial socket ( figure 1 and figure 2 ) or coaxial plug ( image 3 and Figure 4 ), the calibration standard is also called "Offset-Short", especially from figure 2 and Figure 4 As can be seen in the figure, it comprises: an inner conductor part 10 with an adjusting screw 12, an outer conductor part 14, a contact bushing 16, a set screw or set or lock nut 18 and a compression ring 20. The outer conductor part 14 and the contact bushing 16 form a fixed unit. Likewise, the inner conductor part 10 and the adjusting screw 12 form a fixed unit, wherein in the illustrated embodiment the inner conductor part 10 and the adjusting screw 12 are screwed together. The inner conductor part 10 is engaged at 22 by a thread (at figure 2 and Figure 4 Not shown in the cross-sectional view) between the external thread on the adjustment screw 12 and the internal thread on the contact bush 16...

Abstract

A coaxial plug or coaxial socket connected to a coaxial coupler of a device that is to be calibrated, such as a measuring port of a vectorial network analyzer (VNA). The coaxial coupler has an inner conductor part and a coaxial outer conductor part, and has a short-circuit connection provided between the inner conductor part and the outer conductor part. The outer conductor part and the inner conductor part are connected to a contact coupling sleeve so that they can be axially displaced in relation to one another. A contact mechanism is located and configured to act selectively on the contact coupling sleeve, so that the latter creates the short-circuit connection in the form of a detachable electrical contact between the inner conductor part and the outer conductor part, whilst at the same time mechanically fixing the inner conductor part and the outer conductor part in their relative positions.

Description

technical field [0001] The invention relates to a calibration reference in the form of a coaxial coupler with a coaxial air duct, in particular a coaxial plug or a coaxial socket, for connecting a coaxial coupler to an instrument to be calibrated, in particular It is a measurement port connected to a vector network analyzer (VNA), wherein the coaxial coupler has an inner conductor part and an outer conductor part arranged coaxially therewith, and a short-circuit connection is arranged between the inner conductor part and the outer conductor part. Background technique [0002] The high precision of the vector network analyzer lies in that the network analyzer is calibrated by connecting a calibration standard to its measurement port before the actual measurement of the value and phase of the complex reflection coefficient. During this time, a large number of different calibration methods emerged. For system calibration, most calibration methods use no-load, short-circuit and...
