Test system and test method of radio frequency identification index

Abstract

The invention provides a test system and test method of a radio frequency identification index. The test system comprises a shielding box used for placing equipment to be tested, a test antenna is arranged in the shielding box, the test antenna is connected with a radio frequency parameter tester, the radio frequency parameter tester is connected with a computer, and the computer is further connected with the equipment to be tested. Test signals of the test method are sent through the equipment to be tested, the radio frequency parameter tester receives the test signals through the test antenna, the test signals are coupled with the test antenna through the antenna of the equipment to be tested to be transmitted to the radio frequency parameter tester to complete test analysis. According to the test system and test method, a test process and the test method are simplified, production cost of a test fixture is eliminated, test cost is saved, test operation is easy to achieve, and a test controller can be familiar with the test process conveniently; the test speed is high, test efficiency is improved, and a test result is stable and reliable.

Description

【Technical field】 [0001] The invention relates to a test system and a test method for radio frequency indicators. 【Background technique】 [0002] For products with wireless radio frequency functions, it is generally necessary to test the radio frequency parameter indicators of the transmitter and receiver of the product before leaving the factory to verify its performance. The radio frequency parameters include: product transmit power, signal spectrum, frequency error, EVM (Error Vector Magnitude). For the production test process of the product, please refer to figure 1 , The product needs to be tested in two steps before leaving the factory: 1. Wireless board level test, 2. Terminal machine test, wireless radio frequency index test through wireless board test, and wireless throughput test through terminal machine test. [0003] see figure 2 , the existing wireless board-level test system includes: a product under test 1', a radio frequency parameter tester 2', a compute...

AI Technical Summary

Problems solved by technology

[0005] 1. The antenna needs to be disconnected during the test, and the auxiliary test fixture is used for bare-board testing. After the radio frequency index is measured, the antenna can be soldered to carry out the subsequent terminal machine test. The process is complicated; if the antenna is not disconnected, the RF signal There will be two streams, one of which will be sent to the receiving end of the test fixture, and the other will be transmitted through the antenna end, which will affect the test results and make the test inaccurate;

[0006] 2. The existing wireless board-level test requires additional test fixtures for auxiliary tests, which increases test costs

Therefore, the invention patent does not have any inspiration for the present invention
