Testing device and testing method of RF probe

Abstract

The invention discloses a testing device and a testing method of an RF probe, which relate to the technical field of radio frequency detection. The testing device is characterized by comprising an RF coaxial housing allowing the RF probe to be inserted for detection, a test adapter which is mounted at an axial end portion of the RF coaxial housing and used for acquiring an output signal of the RF probe, and a host control end electrically connected with the test adapter, wherein the RF coaxial housing comprises an inner shaft barrel having a mounting hole for inserting the RF probe, an outer bottom barrel sleeving and fixed to one side of the inner shaft barrel, an outer top barrel sleeving one side of the inner shaft barrel in a slided manner, and an elastic member arranged between the outer bottom barrel and the outer top barrel and having an elasticity driving the outer top barrel to be away from the outer bottom barrel; a limiting pair used for limiting the outer top barrel from sliding out of the inner shaft barrel is arranged between the outer top barrel and the inner shaft barrel; and when the outer top barrel is limited by means of the limiting pair, the axial end surface, away from the test adapter, of the outer top barrel protrudes from the axial end surface, away from the test adapter, of the inner shaft barrel. The testing device and the testing method have the advantage of comprehensively measuring the performance of the RF probe.

Description

technical field [0001] The invention relates to the technical field of radio frequency detection, more specifically, it relates to a test device and a test method of a radio frequency probe. Background technique [0002] There will be various signal transmissions in the conductors in the PCB circuit board. In order to increase the transmission rate, the frequency must be increased. If the line itself is different due to factors such as etching, stacking thickness, and wire width, the impedance value will change. It will distort the signal and lead to a decrease in the performance of the circuit board, so it is necessary to control the impedance value within a certain range. [0003] In order to ensure the normal conduction state of the circuit on the printed circuit board, it is common to detect RF signals on the printed circuit board circuit at present. It is to weld the RF coaxial connector with a jack on the signal point on the printed circuit board, and then use A probe...

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
