Abstract

The invention discloses a time domain reflectometry single end apparatus and method of a radio frequency co-axial coupler. The apparatus includes a to-be-detected assembly, a co-axial cable, a networkanalyzer and a computer. The to-be-detected assembly includes a female-to-female radio frequency co-axial coupler, a male-to-female radio frequency co-axial coupler and a load resistor which are connected in series. An output end of the network analyzer is connected to one end of the co-axial cable, and the other end of the co-axial cable is connected to the female-to-female radio frequency co-axial coupler of the to-be-detected assembly. An output end of the network analyzer is connected to a computer, and the network analyzer is intended for performing time domain reflectometry on the to-be-detected assembly so as to obtain a reflectometry voltage signal of the to-be-detected assembly and input the reflectometry voltage signal from measuring the computer so as to obtain the position ofthe fault of the male-to-female radio frequency co-axial coupler. According to the embodiments of the invention, the apparatus herein can analyze the impedance mismatch of the radio frequency co-axialcoupler, and can determine the position of the fault of the radio frequency co-axial coupler in a precise manner.

Description

technical field [0001] The invention relates to the technical field of radio frequency coaxial connector testing, in particular to a time domain reflection single-ended testing device and method for radio frequency coaxial connectors. Background technique [0002] The radio frequency coaxial connector refers to the connecting part of the connector and the electronic equipment. It is a connector connected by a radio frequency cable, also known as a cable connector. There are many series of RF coaxial connectors, such as N, BNC, TNC, SMA and other series. When performing performance tests on RF coaxial connectors, by measuring high-frequency parameters (such as insertion loss and voltage standing wave ratio) in the frequency domain, the matching performance of the connector can be analyzed as a whole, but the internal specific The impedance matching situation cannot be analyzed and judged intuitively, and the fault location of the RF coaxial connector is not accurately locate...
