Abstract

The invention relates to a radio frequency switching box and a system for testing the radio frequency consistency of terminals. The radio frequency switching box comprises a first radio frequency testing link which is used for enabling a system simulator to be connected with a to-be-detected terminal; a second radio frequency testing link which is used for enabling a microwave signal source to be connected with the to-be-detected terminal; a third radio frequency testing link which is used for enabling a vector signal source to be connected with the to-be-detected terminal; a fourth radio frequency testing link which is used for enabling a frequency spectrum analyzer to be connected with the to-be-detected terminal; and an interface unit which is used for providing a connection interface for the connection of the radio frequency switching box with the system simulator, the microwave signal source, the vector signal source, the frequency spectrum analyzer and the to-be-detected terminal. The switching box can automatically switch the radio frequency testing links in a testing process of radio frequency consistency, completes various types of testing items of technical standards relative to the standard requirements for consistency testing of an LTE terminal, saves the investment cost of testing, improves the testing efficiency, simplifies the testing operation, and reduces the requirements for the professional skill of a tester.

Description

technical field [0001] The invention relates to the technical field of wireless communication testing, in particular to a radio frequency switching box and a terminal radio frequency consistency testing system. Background technique [0002] In various testing and verification of mobile communication terminals, testing is the verification of terminal design, scheme and product, an important part of product quality inspection, and a key means to promote product maturity and perfection. The mobile communication protocol standard clearly defines the behavior and response of the mobile communication terminal in various states. Through the consistency test, you can check whether the behavior of the mobile communication terminal complies with the protocol standard. Only the mobile communication terminal that successfully passes the consistency test can be Be recognized by operators and users. [0003] The conformance test of the mobile communication terminal is mainly divided into...
