Test device and test method for radio frequency probe

Abstract

The invention discloses a radio frequency probe testing device and method, and relates to the technical field of radio frequency detection. Its technical points include a radio frequency coaxial shell for radio frequency probe insertion detection, a test adapter installed on the axial end of the radio frequency coaxial shell for obtaining the output signal of the radio frequency probe, and a host control device electrically connected to the test adapter The radio frequency coaxial shell includes an inner shaft tube with a mounting hole for the insertion of a radio frequency probe, an outer bottom tube sleeved on one side of the inner shaft tube, and an outer bottom tube sleeved on one side of the inner shaft tube. The top cylinder and the elastic member disposed between the outer bottom cylinder and the outer top cylinder have an elastic member that drives the outer top cylinder away from the elasticity of the outer bottom cylinder; a device is provided between the outer top cylinder and the inner shaft cylinder to restrict the outer top cylinder from slipping out of the inner shaft cylinder The limit pair; when the outer push cylinder is limited by the limit pair, the axial end surface of the outer push cylinder away from the radio frequency adapter protrudes from the axial end surface of the inner shaft cylinder away from the radio frequency adapter, The invention has the advantage of comprehensively measuring the performance of the radio frequency probe.

Description

Technical field [0001] The present invention relates to the field of radio frequency detection, and more particularly, it relates to a test apparatus and test method of a radio frequency probe. Background technique [0002] There will be various signal delivery in the conductor in the PCB circuit board. When it improves its transmission rate, the line itself must cause changes in impedance values ​​if the line itself is different from factors such as etching, laminate thickness, and wire width. Make the signal distortion, resulting in a decrease in the use of the line board, so it is necessary to control the impedance value within a certain range. [0003] In order to ensure that the line on the printed circuit board is normal, it is often common to detect the operation of the RF signal in the printed circuit board circuit, and is a radio frequency coaxial connector with a jack on the printed circuit board, and then utilized A probe tool is in contact with the radio frequency coa...

AI Technical Summary

Problems solved by technology

Due to the differences in the apertures of the RF coaxial connectors of different PCB board manufacturers, there are some differences in the angle and position of the RF probe inserted into the RF coaxial connector, and the above differences will cause some RF probes that were originally inspected to pass the test. In the process of PCB board inspection by PCB board manufacturers, mistakes are made; therefore, there is an urgent need for a test device for RF probes to conduct comprehensive tests on RF probes
