Abstract

The invention discloses a 1800M radio frequency consistency emission intermodulation test method and device. The method comprises the following steps: connecting a terminal to be tested with a radio frequency consistency measuring device and external equipment through a radio frequency cable according to a preset rule to form a test channel; configuring cell relevant parameters of a comprehensivemeasuring instrument according to the preset rule, and setting initial frequency points and initial bandwidths; issuing a test configuration to the terminal to be tested through the test channel; sending an intermodulation interference signal by a signal source according to the preset rule, and returning the signal by a terminal under test according to the test configuration; combining the intermodulation interference signal with the signal returned by the terminal under test to form a test signal; confirming a test result under the frequency points and the bandwidths through the measurement of the test signal by the comprehensive measuring instrument and a frequency spectrograph; and sequentially modifying the frequency points to be tested and the bandwidths to be detected, so as to obtain the test results under different frequency points and different bandwidths. The method and the device provided by the invention improve the efficiency and also improve the accuracy and reliability of the emission intermodulation test.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a method and device for testing 1800M radio frequency conformance emission intermodulation. Background technique [0002] At present, in the field of mobile communication technology, with the continuous development of technology, the integration of communication base stations is getting higher and higher, the frequency band coverage is expanding from GSM, UMTS, LTE to MassiveMIMO, and the transmission power range of base stations is also gradually expanding. The number of base station antennas of the fifth generation mobile communication system (Fifth Generation, 5G) has increased by dozens of times compared with previous generations. [0003] The LTE1800M private network frequency band is different from the public network, and the traditional communication equipment test environment is not compatible, especially for the emission intermodulation test of ra...
