Detailed Description
The invention is described in further detail below with reference to the attached drawings and detailed description:
The invention provides a 5G terminal rapid test system and a 5G terminal rapid test method based on a test sequence, which mainly aim at the rapid test requirement on a 5G terminal production line, realize the requirement of performing a large number of tests in a very short time through the control of the test sequence, and greatly improve the test efficiency.
The test sequence mainly refers to that in order to complete a test target, the characteristic of a tested terminal is combined, a test flow is planned, and a test sequence is artificially set, wherein the test sequence defines the time of each test flow in the test, and the frequency point, the power and the related parameters of a test signal, such as bandwidth, a modulation mode, a channel type, an RB number and the like, which are tested in each test flow. The sequence contains control information for the test instrument and the test terminal, and mainly aims to enable the test instrument and the test terminal to generate and receive signals through the same rhythm, and send and receive fixed signals at fixed time points, so that the purpose of rapid measurement is achieved.
The test system and the test method are mainly realized by combining software and hardware. On the hardware side, the radio frequency of the test instrument mainly comprises an FPGA (field programmable gate array) for controlling a transmitting frequency point, transmitting power, a receiving frequency point and receiving power through an SPI (serial peripheral interface). Because the minimum test time requirement reaches microsecond level, the traditional method for controlling the radio frequency in real time cannot meet the requirement of rapid test, and the method needs to be matched with a software side at the moment to realize rapid control of the radio frequency.
On the software side, in order to meet the test requirement, according to the issued manually preconfigured test sequence, the radio frequency control parameters of the instrument are generated. The parameter is in the form of an array, which contains two types of information, one type is special information containing time information, and the other type is common information only containing the address and the value of the control radio frequency register. One piece of special information corresponds to a set of general information. According to the time planning in each test sub-flow in the test sequence, calculating the time point of radio frequency switching, writing the information into an array, then writing the radio frequency control information corresponding to the time point backwards in sequence until the information of the group is written, calculating the next time point to generate and write the next information, and finally writing the generated complete control sequence into the DDR, wherein the sequence comprises the register configuration of radio frequency control and the time point of the configuration needing to be effective. The whole test sequence takes time as a base point, and corresponding operations are carried out at specific time points, including control of radio frequency and data acquisition and measurement. By combining software and hardware, the rapid measurement of the 5G terminal in the extremely short time specified by the test sequence is realized. In the scheme, the radio frequency control based on the test sequence has extremely high requirement on time precision, and the time required by the radio frequency control to take effect is added, so that the software side needs to fully consider the two points when generating the radio frequency control sequence, and then combines the test requirement to achieve accurate radio frequency control and test.
The test method is mainly applied to 5G terminal production line test, and the whole test system is mainly divided into 3 parts as shown in figure 1: terminal test equipment platform, test terminal, test instrument. The terminal test equipment platform is a control module in the whole system, and is mainly used for carrying out service scheduling on the whole test flow, so as to realize test and data statistics of the test terminal, and the terminal test equipment platform is mainly used for controlling the other two parts through a communication module: one is a test terminal which is placed in a terminal test equipment fixture; the other is a test instrument, and the test of the test terminal is mainly realized by the test instrument.
The test instrument comprises a radio frequency hardware module and a baseband processing module, and information exchange is carried out between the radio frequency hardware module and the baseband processing module through an SPI interface of the FPGA. The test terminal and the radio frequency hardware module are connected by radio frequency, the FPGA controls the radio frequency hardware to switch frequency points and power through SPI, and the acquisition of information data of the test terminal is completed.
The 5G terminal rapid test method based on the test sequence is the core of the test instrument, and completes the rapid switching control of the radio frequency and the terminal measurement, and the schematic block diagram is shown in figure 2. The FPGA controls the radio frequency hardware to switch frequency points and power through SPI, and for accurate control, a control sequence is required to be generated through calculation, and the corresponding control register value is sent at the corresponding time point, so that the signal transmission of the test terminal and the signal reception of the test instrument are in a completely aligned state, and equipment automation test is performed.
The implementation of the whole test method mainly comprises the cooperation of a software algorithm and FPGA logic, and the control of radio frequency hardware is realized through an SPI interface of the FPGA, so that corresponding measurement is carried out. The equipment platform sends the test sequence to the test terminal and the test instrument simultaneously, and the test terminal and the test instrument start timing at the same time point in a time synchronization mode. After receiving the test sequence, the instrument software calculates the configuration value of the corresponding radio frequency register according to the configuration of the radio frequency point, the power and the like in the test sequence, and generates a corresponding time axis according to the time length of each measurement period. After the test terminal and the test instrument start time are synchronized, timing starts, and the FPGA can send the value of the radio frequency control register to the radio frequency hardware through the SPI interface at the corresponding time point, so that the aim of accurate radio frequency control is achieved.
Summarizing, a 5G terminal rapid test method based on a test sequence comprises the following steps:
step 1, manually pre-configuring a test sequence, wherein the sequence comprises the time of each test flow, and the frequency point, the power and the related parameters of a test signal tested in each test flow;
Step 2, the terminal test equipment platform simultaneously transmits the test sequence to the test terminal and the test instrument;
Step 3, after the software in the test instrument receives the test sequence, calculating a configuration value of a corresponding radio frequency register according to the configuration of radio frequency points, power and the like in the test sequence, and generating a corresponding time axis according to the time length of each measurement period;
and 4, after the starting time of the test terminal and the test instrument is synchronized, starting timing, and sending the value of the radio frequency control register to the radio frequency hardware through the SPI interface at a corresponding time point by the FPGA so as to achieve accurate radio frequency control and complete the acquisition of the data of the test terminal.
The test method is suitable for the scenes of terminal transmitter test, terminal receiver test and simultaneous test of the terminal transmitter and the terminal receiver. For these three typical test scenarios, different measurement controls are performed separately.
