Test tool for 6-18GHz amplitude-phase consistent frequency conversion assembly

Abstract

The invention discloses a test tool for a 6-18GHz amplitude-phase consistent frequency conversion assembly. The test tool comprises a cabinet, and a power supply module, a power supply conversion board, a single-pole five-throw switch, a local oscillator source, a control module and a crystal oscillator which are arranged in the cabinet, wherein the power supply module is used for providing a power supply voltage, one part provides a power supply for an internal module, and the other part provides a power supply for a tested assembly; the power supply module is connected with the single-pole five-throw switch through the power supply conversion board; the single-pole five-throw switch divides an external radio frequency input signal into five paths of signals capable of switching channelsand provides the five paths of signals for the tested assembly as signal input of each branch; the local oscillator source provides a local oscillator signal for a tested assembly; and the control module is used for switching the working states of the single-pole five-throw switch, the local oscillator source and the tested assembly, and sending test data to an external operation platform in realtime through a 485 control line. The test tool has the advantages of being low in cost, stable in performance, accurate in test result and easy to operate.

Description

technical field [0001] The invention relates to a testing technology of a microwave component, in particular to a testing tool for a 6-18GHz amplitude-phase consistent frequency conversion component. Background technique [0002] At present, due to the vigorous development of naval equipment, 6-18GHz amplitude-phase frequency conversion components, as an important part of the radar receiving front end, are being designed and produced in large quantities, and the delivery cycle and quality requirements are also getting higher and higher. Therefore, the test cycle and quality control of the production process of such components are extremely important. [0003] For the traditional 6-18GHz amplitude-phase consistent frequency conversion component test method, the usual test plan requires 6 signal sources (4 RF branches, 2 local oscillator branches), 1 power supply, 1 computer, 1 Spectrum analyzers and a large number of test lines, etc., have the following disadvantages: 1) hea...
