Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another.
Fig. 1A and fig. 1B are schematic application environments of the radio frequency testing method in the charging process in one embodiment, respectively. As shown in fig. 1A and 1B, the application environment includes a communication product 120, an rf switch matrix 140, and a test equipment 160. The number of the test devices can be two or more. The radio frequency switch matrix is mainly used for controlling a transmission path of radio frequency signals, and is generally formed by combining a plurality of radio frequency switches through a certain relation to form a row-column intercommunication scale radio frequency switch form. The radio frequency switch matrix is mainly widely applied to many radio frequency communication systems such as wireless communication, electronic reconnaissance and radar, and is an essential part for switching channels in the systems.
As shown in fig. 1A, the device under test (communication product 120) inputs the transmitted a-channel rf signal into the rf switch matrix 140. The rf switch matrix 140 may output one rf signal a as two identical rf signals a1 and a2, where the two rf signals a1 and a2 are identical to the rf signal a. The rf switch matrix 140 sends the rf signal a1 to the test equipment a1, and the test equipment a1 performs corresponding rf testing on the received rf signal a 1. The radio frequency signal a2 is sent to the test equipment a2, and the test equipment a2 performs corresponding radio frequency tests on the received radio frequency signal a 2.
As shown in fig. 1B, the communication product 120 transmits two rf signals, one rf signal C and the other rf signal D. The communication product 120 inputs the two transmitted rf signals into the rf switch matrix 140. The rf switch matrix 140 can directly output the rf signal C and output the rf signal D as two identical rf signals D1 and D2, where the two rf signals D1 and D2 are identical to the two rf signals D. The radio frequency switch matrix 140 sends the radio frequency signal C to the test device C, and the test device C performs a corresponding radio frequency test on the received one path of radio frequency signal C. The radio frequency signal D1 is sent to the testing device D1, and the testing device D1 performs a corresponding radio frequency test on the received one-path radio frequency signal D1. The radio frequency signal D2 is sent to the testing device D2, and the testing device D2 performs a corresponding radio frequency test on the received one-path radio frequency signal D2. Of course, the rf switch matrix may include other mimo situations, which is not limited in this application.
Fig. 2 is a block diagram of an exemplary rf test system 200, and as shown in fig. 2, the rf test system 200 includes an rf switch matrix 220 and at least two test devices 240. Wherein the content of the first and second substances,
the radio frequency switch matrix 220 is configured to receive radio frequency signals sent by a device to be tested, where the radio frequency signals include at least one radio frequency signal, and output the at least one radio frequency signal as at least two radio frequency signals;
at least two testing devices 240, configured to receive a path of radio frequency signal output by the radio frequency switch matrix, respectively, and each testing device performs a radio frequency test on the received path of radio frequency signal.
Specifically, the radio frequency test system comprises a radio frequency switch matrix and test equipment. The number of the test devices and the radio frequency signals output by the radio frequency switch matrix have a one-to-one correspondence relationship. Namely, if the radio frequency switch matrix outputs two paths of radio frequency signals, the number of the test equipment is two; if the radio frequency switch matrix outputs three paths of radio frequency signals, the number of the test equipment is three. The radio frequency switch matrix may output one path of radio frequency signals transmitted by the device to be tested as two identical paths of radio frequency signals or multiple paths of radio frequency signals, which is not limited in the present application. Of course, only one rf signal may be output as one rf signal.

The radio frequency switch matrix can output at least one path of received radio frequency signals into at least two paths of radio frequency signals, and the test equipment can simultaneously carry out different tests on the same radio frequency signal.

In this embodiment, the radio frequency switch matrix may output at least one of the received radio frequency signals as at least two radio frequency signals, and then at least two test devices may perform different tests on the same radio frequency signal at the same time. For example, different test devices may respectively test different radio frequency indexes of the same radio frequency signal, where the different radio frequency indexes include one or more parameter data of channel power, adjacent channel power, spectrum template, and spurs. In the traditional method, only one radio frequency index can be tested for one radio frequency signal at a time. Obviously, by adopting the method of the application, different radio frequency indexes of the same radio frequency signal are tested simultaneously, so that the test time is shortened by multiple times, and the test efficiency is greatly improved.
In one embodiment, the test device is a spectrum analyzer or a signal analyzer.

In the embodiment of the application, each testing device receives the radio frequency signal sent by the radio frequency switch matrix and simultaneously performs corresponding testing on the radio frequency signal. In the conventional method, different tests cannot be performed on the same radio frequency signal at the same time. In the embodiment of the application, one path of radio frequency signal is output to at least two paths of radio frequency signals by the radio frequency switch matrix, so that different tests can not be simultaneously performed on the same radio frequency signal. The original different tests which are sequentially carried out are converted into the tests which are carried out simultaneously, so that the test time is greatly shortened.

In the embodiment of the application, the high performance of the 5G network also puts higher requirements on the performance of the 5G communication device, so that various and complex tests are involved in the process of detecting the radio frequency signal of the 5G communication device. In order to improve the radio frequency test efficiency of the 5G communication equipment, at least one path of radio frequency signals sent by the 5G communication equipment are output into at least two paths of radio frequency signals through a radio frequency switch matrix. In this manner, the RF switch matrix then transmits the plurality of RF signals to the plurality of test devices. Each test device performs different radio frequency tests on the received radio frequency signal. The process that only certain radio frequency signals can be tested in sequence in the traditional method is shortened to the process that certain radio frequency signals can be tested at the same time. Obviously, the testing efficiency is greatly improved.
