The invention provides a miniature high-power microwave link parameter conditioning instrument. The miniature high-power microwave link parameter conditioning instrument comprises an electromagnetic shielding case, more than two microwave devices, a temperature collector, a control circuit, a coaxial cable, a radio frequency adapter and a liquid crystal display module, Wherein each microwave device, the coaxial cable and the radio frequency adapter are connected to form a microwave link; the microwave devices, the temperature collector and the liquid crystal display screen are controlled by the control circuit to communicate with each other, and a control command is issued through the control circuit to control the corresponding microwave link to work; The control circuit transmits the working state information of the microwave device and the information collected by the temperature collector in the case to the liquid crystal display module, and the information is displayed by the liquid crystal display screen on the front panel in real time; The microwave device is integrated to the front panel of the electromagnetic shielding case through a coaxial cable, and the front panel is provided with a radio frequency adapter for connecting the microwave device. The system is high in integration level, facilitates the integrated application of a comprehensive automatic test system, and can greatly improve the test efficiency.
Description
technical field [0001] The invention relates to the technical field of comprehensive automatic testing of electronic information equipment, in particular to a miniature high-power microwave link parameter conditioning instrument. Background technique [0002] In order to ensure the test requirements of microwave signal performance testing of microwave radio frequency systems and components in the system under test, combined with the system platform signal source, spectrum analyzer, power meter and various simulators and other instrument resources, microwave link conditioning equipment is required to Realize resource expansion of radio frequency measurement channels, attenuation adjustment of high-power signals, microwave power matching and other functions. [0003] At present, the high-power microwave accessories supporting the microwave test link, such as attenuators, loads, couplers, etc., are large in size and are scattered on the ground of the test site, with poor perfor...
