Abstract

The invention relates to a signal testing device, system and method and a storage medium. According to the method, a control assembly, a radio frequency (RF) matrix assembly, a first switching assembly and a second switching assembly are included, the RF matrix assembly comprises a plurality of signal transmission channels, and the total number of the signal channels in the RF matrix assembly is larger than a preset threshold value. The control assembly controls the corresponding number of target signal transmission channels to be conducted according to the number of the to-be-tested signal channels, so that each target signal transmission channel obtains a test signal through the first switching assembly, and outputs the test signal to the test equipment through the second switching assembly. In the scheme, the RF matrix assembly can realize the conduction of multiple signal channels, for example, the RF matrix assembly comprises at least eight signal channels, and is suitable for an output test scene of multi-channel signals in the prior art, so that the complexity that a four-channel signal test device needs to be manually disassembled and assembled in the prior art is avoided, and the test efficiency is improved. And the signal testing efficiency in a multi-channel signal testing environment is improved.

Description

technical field

[0001] The present application relates to the technical field of signal testing, in particular to a signal testing device, system, method and storage medium. Background technique

[0002] With the continuous improvement of the data signal transmission rate of digital products, the reliability requirements for the transmission signal are becoming more and more stringent, and the signal test, as the key basis for judging the signal quality, has become more and more the object of focus.

[0003] In the prior art, a 4-channel vector network analyzer (VNA) is usually used to test the chassis, and the 4-channel signal test is performed according to the signal test specifications of the industry association, or a third-party test software is used to perform the corresponding signal test through algorithm analysis at the software level .

[0004] However, for the scenario of multi-channel signal testing, due to the limitations of channel testing in existing signal t...
