Abstract

The invention relates to the technical field of wireless radio frequency, in particular to a board test calibration test method for use in wireless radio frequency test. The method comprises the following steps: sampling a most-concentrated gain value from a sample machine, and building a multi-machine test environment by using a plurality of servers; writing the counted calibration gain value into Dut; and partially sampling the Dut into which the fixed gain value is written. By adopting the board test calibration test method, the test time is shortened from at least 90 seconds in wireless calibration to be less than 30 seconds, and the test stability is improved greatly without using a radio frequency environment, so that a large number of radio frequency instruments can be saved for production, the test tool cost is reduced, the efficiency of product test can be increased, and the stability of product test can be improved.

Description

In a kind of less radio-frequency test, plate is surveyed calibration test method

Technical field

The present invention relates to a kind of wireless radio-frequency field, relate in particular to plate in a kind of less radio-frequency test and survey calibration test method.

Background technology

With the communication product of radio function module in process of production, while having a large amount of wireless chips to produce, wireless emission parameter is calibrated, the calibration of wireless transmission parameter directly has influence on the quality of wireless performance, and then affects product wireless telecommunications performance and user's experience.

Development along with wireless telecommunications and radio-frequency technique, communication product on market is substantially all integrated radio function, the quantity of wireless product also constantly increases, for producing, the time of wireless calibration substantially all takies wireless plate and surveys half even more time, and wireless calibration is to environment line, and the requirement of tool is all stricter, so for production test, wireless calibration is the problem points that seriously restricts production efficiency.

Summary of the invention

The object of the present invention is to provide plate in a kind of less radio-frequency test to survey calibration test method, solved prior art low to the wireless calibration steps efficiency of communication products, the problem that accuracy is not high.

For addressing the above problem, the technical solution used in the present invention is:

In less radio-frequency test, plate is surveyed a calibration test method, comprises the following steps:

Step 1, from model machine sampling, carries out wireless calibration and test to the DUT of all model machines (Devices to test), then records the calibration data of the upper plank of all DUT, adds up and analyze the lumped values of all calibration gain (gain) values;

Step 2, is used the switch of more than mouthful and a up plank of wan as multiple machine servicer, configures corresponding vlan in multiple machine servicer, builds multimachine test environment;

Step 3, is used multiple machine servicer that the good calibration gain value of described statistics is write in Dut in batches;

Step 4, to writing the fixedly Dut of gain value, do part sampling observation, obtain the gain value in Dut, control the modulation signal that wireless RF tester sends designated mode and amplitude, to Dut, issue wireless instructions receiving radio data bag and obtain Dut receptivity index, after testing and accepting performance index, under send instructions and make Dut stop receiving radio data bag, after treating that Dut stops receiving radio data bag, under send instructions and make the modulation signal of Dut transmitting designated mode and amplitude, after Dut has launched modulation signal, controlling wireless RF tester reception Dut transmits and analyzes Dut emitting performance index.

Adopt the beneficial effect that technique scheme produces to be: the present invention drags four to carry out wireless calibration without producing line with expensive less radio-frequency instrument, and follow-up needs are used wireless Ban Ce QA testing software to carry out part to take a sample test; Multimachine is wireless, and gain value writes, and not only the testing time is reduced in 30 seconds by original wireless calibration at least 90 seconds above, and does not need the stability of using radio frequency environment to make test also significantly to improve; So both can save a large amount of radio frequency instruments reduction testing tool costs for producing, and can promote efficiency and the stability of production test.
