Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] In the specific implementation of the present invention, an analog TV mobile terminal production test is taken as an example, wherein the power divider is a two-channel power divider, and the terminal under test is a motherboard system with 50 ohm impedance.

[0025] see figure 1 , the signal generator 101 sends a signal to the power divider 102, and the power divider 102 divides the signal into several channels, and connects the tested terminals 1041 and 1042 respectively through the test fixtures 1031 and 1032, and the tested terminals 1041 and 1042 decompose the signal Transfer to computer 105 for display after adjustment. As an embodiment, the power splitter is ZFRSC-42 produced by Minicircuits. ZFRSC-42 is a power splitter with single-end input and two output ports. according to figure 1 The test method can be i...

Abstract

The invention discloses a radiofrequency test system and a radiofrequency test method, which adopt a power divider. The power divider divides a signal of a signal generator into a plurality of channels for a plurality of ports to test, therefore, the system and the method can realize that one test instrument satisfies the test of a plurality of test ports during the mass production test, improve the service efficiency and the production efficiency of the instrument, reduce production test cost, and solve the mutual interference and system instability caused by multi-port test due to the fact that the special design is performed on a test fixture.

Description

technical field [0001] The invention relates to the field of communication testing, in particular to a radio frequency testing system and method. Background technique [0002] With the development of electronic technology, more and more electronic devices are used in various fields of production and life. In order to ensure that each product coming out of the factory meets the requirements of function realization and performance, corresponding tests must be carried out on these products during the research and development stage and mass production. At different stages, the test focus and test methods and test requirements may be different. In the production test stage, the test efficiency issue is particularly important, using less test equipment to complete more test tasks in a short period of time with less manpower. [0003] At present, the mobile terminal RF performance test method is basically: the terminal to be tested establishes a connection with the test instrumen...
