Description
Technical field
The present invention relates to a kind of full-automatic height that can be realized and tested automatically polymorphic type radio-frequency module and multi-performance index
The automatic testing equipment of coverage rate may be directly applied to all kinds of radio-frequency modules and quickly test all referring to mark automated high-precision.
Background technique
With the development of measuring technology and artificial intelligence, automatic test technology gradually get rid of profession customize to modularization,
Generalization development.The test of wireless telecommunications system development phase RF index currently mainly uses half that tester's whole process is on duty
Automatic test scheme, then by testing, expert is accomplished manually the data analysisization in later period and test problem positions.Above-mentioned work
Efficiency can not fully meet the demand of current research and development task.The measuring technology of original adoption is manual testing, tester
It should be understood that the data being likely to occur in testing standard, measurand, instrument and meter, test method and test, to tester
It is required that very high.Repeated multiple times plug connecting line be easy to cause damage and the cable characterisitic parameter of precision instrument and equipment in test process
Variation.The defects of time-consuming by manual testing, error is big, at high cost leads to it, and oneself can not be adapted to electronic equipment complication, collection
At the development trend of change.Tens of thousands of even hundreds of thousands are generally required for the stability test project of long-time performance test etc
Secondary repetitive operation, electronic equipment require to carry out extreme environment simulation test before investment large-scale production.It is such
Test item, manual testing can not complete.The process standardized the most can be applied to and survey each time by automatic test
In examination activity, to avoid influence of the human factor to test result, test result.Professional Auto-Test System specific aim
By force, convenient test, but its test software used is not standardized with tool interface system, just for some specific test item
Research and development, versatility, portability are very poor.
As various new technologies, new process and new device are widely used in all kinds of transmitters, receiver, frequency converter, division
The radio-frequency apparatus such as road device, equipment performance also make its performance test increasingly complex while raising.It is numerous for type of modules to penetrate
For frequency microwave generic module is developed, it includes gain, power, noise, standing wave, isolation that module, which needs main performance index to be tested,
Degree, non-linear distortion, phase characteristic, switching time, operating current voltage and module multiple contents such as working condition,
The test verifying of these indexs usually requires to realize respectively using different surveying instruments by repeatedly measuring.It is connect with broadband
For receiving frequency conversion channel module, the main indicator for needing to debug test includes link gain and flatness, noise coefficient, P1dB
Voltage and current etc. when compression point, switch isolation degree, port standing wave, channel isolation and module work.When index test, chain
The indexs such as road gain and flatness, P1dB compression point are usually required using the measuring instruments such as microwave signal source and frequency spectrograph, noise
Coefficient index is needed using noise source and noise-measuring instrument, port standing wave, and the indexs such as isolation are needed using vector network point
Analyzer, and the indexs such as switching time are needed using oscillograph.In traditional radio-frequency performance test, generally directly to radio frequency
Instrument carries out manual hand manipulation, data record etc., and the instrument and equipment used in testing is many kinds of, Various Functions, pass
Connection property is poor, inconvenient, not only high to tester's competency profiling, and test speed is slow, repetitive operation is more, low efficiency, survey
The examination period is long, easily causes human error or mistake, has been unable to meet the needs of batch production.Currently, domestic and international many producers
Still device detection is carried out using manual type, manual record is passed through for the detail parameters of device in test process, to product
It only simply carries out through/failure detection, since high frequency cable is larger by the interference effect of environment, few people in measurement process
It is factor for the interference of measurement, causing can not strict control for quality in production.Even if being surveyed automatically using Custom Prosthesis
Test system causes Auto-Test System equally complicated due to the complexity of radio frequency generic module type, interface and index, test system
Development cost of uniting is high, develops and debugging cycle is long, and debugging, calibration and frequently occurring faults workload are huge.Tested module type
Variation even index and performance local directed complete set, can all cause the exploitation again of Auto-Test System, cause test equipment and
Human resources utilization leads low.The automatization test system customization of radio frequency microwave circuit is stronger at present, and versatility is poor, Wu Fashi
The all standing automatic test of existing type of modules and index test.
In addition, being typically passed through the test of modular debugging stage single index, room temperature in the development of frequency microwave hardware module
Check and accept multiple links such as crucial index test verifying, each ring under the environmental applications simulated conditions such as full index test, high/low temperature/damp and hot
It is all different not to the utmost to save test content, test method even qualified criterion.In Normal Temperature and Acceptance Test, usually need
All standing high precision measurement is carried out to all indexs, test job amount is huge, and conventional automatic testing equipment is generally directed to this
Link customization, can be realized to the quick test record of single module index.And in the index debugging stage of module, it is often necessary to needle
To several combined indexs of an index or some frequency range be repeated detailed comparisons test, manually control measuring instrument and by
Measurement equipment, testing efficiency is low, heavy workload, even needs more people's cooperations that could complete sometimes, the automatic test dress of traditional custom
It sets and does not also have debugging mode, can not adapt to provisional manually control quick testing requirement.During module is developed, if using manual
Test, testing efficiency is low, and test job amount is big, seriously affects project development progress.If every kind of Custom modules test dress automatically
It sets, the opposite investment of detection device is larger, and test equipment utilization rate is low, causes the rising of project development cost.
Summary of the invention
The present invention is for radio frequency class equipment test item is more, the testing time is long, operating process is cumbersome and current frequency microwave
The automatization test system customization of circuit is stronger, and versatility is poor, is difficult to realize all standing of type of modules and index test
Automatic test problem, provide it is a kind of can be realized all standing to polymorphic type radio-frequency module, multiple performance index automation survey
Examination, while being suitable for the whole process application of radio-frequency module development, it can be reduced test measuring device cost input, improve radio-frequency module
