Description
Technical field
The present invention relates to communication test field, the automatic test approach and system of more particularly to a kind of receiving sensitivity.
Background technology
Radio frequency represents the electromagnetic frequency that can be radiated space, and between 300KHz～300GHz, it is one to frequency range
Plant the abbreviation that high-frequency ac changes electromagnetic wave.In theory of electronics, electric current flows through conductor, and magnetic field can be formed around conductor, hands over
Time-dependent current can form the electromagnetic field of alternation, referred to as electromagnetic wave by conductor around conductor.100KHz is less than in wave frequency
When, electromagnetic wave can be absorbed by earth's surface, it is impossible to form effectively transmission, but wave frequency is when being higher than 100KHz, and electromagnetic wave can be with
Propagate in atmosphere, and the ionospheric reflection of Jing atmosphere outer rims, long-distance communications ability is formed, we are with remote biography
The frequency electromagnetic waves of Movement Capabilities are referred to as radio frequency.Radio-frequency technique is widely used in the field of wireless communication.Less radio-frequency is 20 generation
A kind of contactless automatic identification technology of the discipline rise nineties.Less radio-frequency test is main to be included sending test and receiving surveying
Examination.Receiving sensitivity test is to receive an important test index in test.So-called receiving sensitivity is exactly that receiver can
The minimum reception power that correctly useful signal is identified.The receiving sensitivity being wirelessly transferred is linked up similar to people
Audition during talk, improving the receiving sensitivity of signal can make wireless product have the ability for more strongly capturing weak signal.So,
With the increase of transmission range, signal weaker is received, highly sensitive wireless product still can be maintained stably to connect with receiving data
Connect, greatly improve transmission range.
Power splitter (Power divider) be one kind will all the way input signal energy be divided into two-way or multiple-channel output it is equal or
The device of unequal energy.The technical specification of power splitter include frequency range, bear power, main road to branch road distribution be lost,
The isolation between insertion loss, tributary port, voltage standing wave ratio of each port between input and output etc..Power splitter is logical by output
Often it is divided into one-to-two (two outputs of an input), one point three (three outputs of an input) etc..The outfan of one power splitter
Certain isolation is should ensure that between mouthful.
Currently, the popularity rate more and more higher of the mobile terminal such as smart mobile phone, becomes indispensable in people's daily life
Means of communication.Communication is the most basic function of mobile terminal, and the quality of communication performance becomes and judges the important of mobile terminal quality
Standard.The receiving sensitivity of mobile terminal is the important indicator of its communication performance.At present wireless receiving sensitivity test is a bit
Using manually testing, some are automatic tests, but need the artificial test for extracting needs in substantial amounts of test data
Data.Because less radio-frequency has different frequency ranges, pattern, speed and channel, if so using manually carrying out entirely to it
The test in face, is a very huge workload, so can pass through to reduce the test of some speed and channel to reduce mostly
Workload, but so test will not bring certain risk to product comprehensively.Existing automatic test some can export
Very many test datas, the later stage needs the data for manually therefrom extracting needs to be arranged, and is so also to need to expend a large amount of
Time；Some automatic tests then simply output test result by or do not pass through, and the data volume of test is few, and degree of accuracy is low.
The content of the invention
A kind of automatic test approach and system there is provided receiving sensitivity of the present invention, its object is to by one kind certainly
The method of dynamic test less radio-frequency receiving sensitivity, so both can test comprehensively, can save manpower and time again.
The technical scheme that the present invention is provided is as follows：
A kind of automatic test approach of receiving sensitivity, it is characterised in that including step：
Under current test scene, control signal source sends test letter to S100 according to default initial maximum transmit power
Number to Devices to test；
