Problems solved by technology

If this test method is used to test the increasingly popular 3G mobile phones, since the boot time of 3G mobile phones is longer than that of CDMA mobile phones, it will inevitably cause the test instrument to experience a longer idle waiting time, resulting in resource consumption. Waste and loss of testing efficiency

Embodiment 1

[0026] Embodiment one, see figure 1 As shown, in order to realize the fast switching of the mobile phone to be tested by the test instrument in the radio frequency test system of this embodiment, a radio frequency switch interface box is added between the test instrument and the mobile phone to be tested, such as figure 2 shown. Connect the common radio frequency port RF of the radio frequency switch interface box to the test instrument through the radio frequency line, and transmit the radio frequency signal for testing the radio frequency transceiver module inside the mobile phone to be tested. The two sets of test ports of the RF switch interface box are used to connect different mobile phones to be tested; among them, the RF test ports RF1 and RF2 in each group of test ports are used to connect the RF terminals of the mobile phone to be tested, so as to realize the connection between the mobile phone to be tested and the test instrument. RF transmission; the USB test por...

Abstract

The invention discloses a radio frequency test system and a radio frequency test method. While the first equipment to be tested is tested by a testing instrument, the wiring and starting operation of the second equipment to be tested is performed; and after the test of the first equipment to be tested is finished, a test channel of the testing instrument is switched to the second equipment to be tested to test the second equipment to be tested. Zero wait of the testing instrument is realized by combining a radio frequency switching device with a parallel test program, so that the utilization ratio of the testing instrument reaches 100 percent, and the production testing capacity is improved under the condition that the resources of the testing instrument are limited. Meanwhile, an indicator lamp is arranged on the radio frequency switching device and is used for indicating current test conditions. Therefore, on the premise of unnecessarily opening a computer monitor, the test progressand test result can be clearly known through the luminous state of the indicator lamp, and the test operation of the technician is convenient.

Description

technical field [0001] The invention belongs to the technical field of radio frequency testing, and in particular relates to a radio frequency testing system and a radio frequency testing method capable of improving the utilization rate of test instruments. Background technique [0002] In the field of communication manufacturing, testing radio frequency equipment or radio frequency modules is a necessary link before communication equipment leaves the factory. Taking the mobile phone as an example, after each mobile phone is assembled, its performance indicators must be tested with a test instrument, and only the mobile phones that pass the test are allowed to leave the factory for sale. Due to the high daily output of mobile phone products, in the process of testing a large number of mobile phones, the shortage of test instrument resources has become increasingly prominent, which is also the main bottleneck that has always affected my country's mobile phone production capac...
