Abstract

The invention discloses a high-coverage automatic radio frequency index test device. By using the device provided by the invention, quick tests with high coverage can be performed on multi-channel radio frequency indexes of various types of equipment under test. The device provided by the invention is implemented via the technical scheme as follows: an input radio frequency interconnection matrixmodule receives multiple signal sources, a noise source and an output signal of a vector network, and provides source signals such as a microwave vector signal source, the noise source and the vectornetwork output signal to the equipment under test; the equipment under test receives a low-phase noise local oscillator signal and a reference clock signal from a multi-channel local oscillator sourcemodule; the equipment under test completes automatic switching of multiple channels via an output radio frequency interconnection matrix module, and transmits a test signal to an universal measurement instrument; an industrial control computer calls control parameters of the universal measurement instrument and the equipment under test to complete automatic test of the multiple indexes, reads a test result of the universal measurement instrument and automatically generates a test report in a standard format; the artificial configuration test and automatic test on the main indexes of the equipment under test are achieved by using a visual manual control interface.

Description

technical field [0001] The invention relates to a fully automatic high-coverage automatic testing device capable of realizing automatic testing of multi-type radio frequency modules and multi-performance indicators, which can be directly applied to automatic high-precision rapid testing of all indicators of various radio frequency modules. Background technique [0002] With the development of testing technology and artificial intelligence, automatic testing technology is gradually getting rid of professional customization and developing towards modularization and generalization. The radio frequency index test in the research and development stage of wireless communication equipment currently mainly adopts a semi-automatic test plan in which testers are on duty throughout the process, and then the test experts manually complete the later data analysis and test problem positioning. The efficiency of the above work cannot fully meet the needs of the current research and develop...
