Abstract

The embodiment of the invention discloses a system and method for testing radio frequency (RF) of a long term evolution (LTE) base station. The system comprises a signal generator, a spectrum analyzer, a control personal computer (PC), an internal local area network (LAN), a circulator, an RF switch, a remote radio unit (RRU) and an auxiliary control unit. The signal generator, the spectrum analyzer, the control PC, the circulator, the RF switch, the RRU and the sub-control unit are connected to the internal LAN by network cables and used for interacting orders and data by the internal LAN. According to the embodiment of the application, automatic RF test demands of an LTE system can be met.

Description

technical field

[0001] The present invention relates to the test technology in the communication field, in particular to a radio frequency test system and method for an LTE base station. Background technique

[0002] The existing LTE (Long Term Evolution, long-term evolution) E-NodeB (Evolved NodeB, evolved Node B) mostly adopts a distributed structure, and the distributed base station refers to the BBU (Base Band Unit, base station processing unit) and RRU (Remote Radio Unit (radio remote unit) is a base station mode in which each is placed separately as an independent module and connected through an optical fiber. Among them, the RRU mainly implements functions such as a radio frequency transceiver and a power amplifier. In actual use, in order to ensure the stability of the system, it is necessary to conduct radio frequency tests on the RRU.

[0003] From the content of the test, the radio frequency test mainly includes the transmitter radio frequency test and the recei...
