Problems solved by technology

Since the test in the aging process is mainly aimed at the most basic indicators of the radio station, the test workload of a single radio station is not large, so the time taken to switch the radio interface may reach more than one-third of the entire test time

Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0036] Such as figure 1 , a signal switching gating device between a radio station and a test instrument. According to the characteristics of the radio interface signal, a series of switch matrices are used. Through simple switch operations, the test cable of the radio station under test can be quickly connected to the test instrument. It avoids the operation link of manually replacing the cables one by one, which greatly improves the test efficiency.

[0037] The function of the present invention is to set up a transfer bridge between test instruments and between numerous tested stations, so that the relevant interface of each tested station can be quickly connected to the test instrument through this bridge, without will be affected by other stations. The principle b...

Abstract

The invention discloses a signal switch gating device between broadcasting stations and test instruments. The signal switch gating device comprises n key switches respectively connected with the test instruments, each key switch contains N+1 small switches which are linked, and the first small switch to the Nth small switch of the ith key switch are respectively and directly connected with a non-radio-frequency signal interface of the ith broadcasting station; the N+1th small switch of the ith key switch controls an ith radio-frequency switch unit and is used for connecting or switching off radio-frequency signals of the ith broadcasting station; wherein n is greater than or equal to 2, 1 is smaller than or equal to i which is smaller than or equal to n, and N is greater than or equal to 1. With the signal switch gating device and method, operation steps of manually replacing cables one by one are avoided, and test efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of radio performance testing, in particular to a signal switching gating device and method between a radio station and a testing instrument. Background technique [0002] A radio is a communication device that uses radio waves to receive and transmit voice or data. The working frequency band of the radio station is generally lower than the microwave frequency band. Specifically, it is divided according to the working frequency band. There are medium and long wave radio stations, short wave radio stations, and ultrashort wave radio stations. The radio station is mainly used for long-distance communication of several kilometers to thousands of kilometers, and the channel attenuation is very large. Therefore, the radio station generally does not support broadband communication, and usually only supports voice and low-to-medium rate (≤1Mbps) data communication services. Therefore, the external interface of the radio stat...
