Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

Fig. 1 is a flow chart illustrating a method for detecting radio frequency hardware, according to an exemplary embodiment, as shown in fig. 1, the method comprising the steps of:

step 101, after the configured signal source instrument is connected with a first detection port of the radio frequency hardware, configuring the radio frequency hardware by using software programming.

Illustratively, after the configuration of the signal source instrument is completed, the output signal port of the signal source is connected with the first detection port of the radio frequency hardware, that is, the receiving antenna port of the radio frequency hardware, or the receiving antenna port of the whole mobile terminal. If the radio frequency hardware is configured first and then the radio frequency hardware is connected with the signal source instrument, a fault may be caused by the live connection operation, and in order to ensure safety, it is preferable to connect the radio frequency hardware when the radio frequency hardware is not powered on, and then configure the radio frequency hardware and start the power-on operation.

Step 102, after an output switch of the signal source instrument is turned on and the configured radio frequency hardware is started, a first test signal output by the radio frequency hardware is sampled and analyzed by using a preset sampling tool and an analysis tool so as to determine a real part and an imaginary part of the first test signal.

The sampling tool comprises a Trace tool, a vivado tool and a logic analyzer tool; the analysis tool comprises: matlab software and C + + software.

For example, since the signals are all real signals in the actual transmission process, for the convenience of digital signal processing, complex signals are adopted at the receiving end, that is, the signals in the transmission process need to be processed into baseband complex signals (i (t) + jq (t)), and then a complex exponential carrier signal is multiplied as the transmitted modulated complex signal, so that the receiving end also processes the received signals into complex signals. Compared with complex signals, the I-path signal and the Q-path signal can more intuitively and clearly express the signal characteristics by using an analysis tool by using a method of separating complex signals, so that the processing is convenient; meanwhile, as the I path signal and the Q path signal of the complex signal are used as orthogonal signals, the mutual interference cannot be caused, and for a single carrier signal of an external information source, a single path signal can well represent the characteristics of an original signal and can also be used for analyzing only one path signal; and if a certain section of data of a certain path of signal is abnormal, the judgment can be carried out by analyzing the waveform condition of the signal at the time point corresponding to the other path of signal. In addition, if the external source adopts a modulation signal, whether the signal is abnormal is not easy to see in the time domain, and whether the modulation wave is normal can be roughly judged through experience according to the waveform of the I/Q in the time domain, so that the judgment operation is simplified.

Step 103, comparing the real part and the imaginary part of the first test signal with the first reference data, and determining whether the radio frequency hardware has a fault.

Illustratively, the first reference data is a standard signal when the signal source instrument is connected to the first detection port of the rf hardware, and is determined under the conditions of fixed signal source instrument output signal strength and receiving gain after the rf hardware has completed configuration, and ensuring the amplitude, phase, frequency spectrum and real-domain waveform of the output signal of the signal source instrument, for example, according to factory specifications and reference documents of the rf hardware, or by using an empirical value.

And step 104, when the radio frequency hardware has a fault, connecting the signal source instrument with the second detection port and the third detection port of the radio frequency hardware in sequence, and repeating the operations from the step 102 to the step 103 until the fault position of the radio frequency hardware is determined.

Illustratively, after determining that the radio frequency hardware has a fault according to the operations of steps 101 to 103, this step locates the specific location of the fault in the radio frequency hardware by connecting the second detection port and the third detection port in sequence.

And the second detection port is positioned behind an antenna switch of a receiving channel of the radio frequency hardware, and the third detection port is positioned behind a filter of the receiving channel of the radio frequency hardware, so that the fault is positioned according to the comparison result in sequence.

In summary, according to the detection method for the radio frequency hardware provided by the present disclosure, after the configured signal source instrument is connected to the first detection port of the radio frequency hardware, the radio frequency hardware is configured by using software programming; after an output switch of a signal source instrument is turned on and radio frequency hardware which is configured is started, sampling and analyzing a first test signal output by the radio frequency hardware by using a preset sampling tool and an analyzing tool so as to determine a real part and an imaginary part of the first test signal; determining whether the radio frequency hardware has a fault by comparing a real part and an imaginary part of the first test signal with first reference data; when the radio frequency hardware has a fault, the signal source instrument is sequentially connected with the second detection port and the third detection port of the radio frequency hardware, and the signal acquisition and comparison steps are repeated until the fault position of the radio frequency hardware is determined. Therefore, the software programming mode is matched with the signal source instrument to verify and locate the radio frequency hardware receiving channel, the usability and the fault location of the radio frequency hardware receiving channel can be quickly and effectively verified, a baseband platform and a version are not needed, the detection flow can be solidified, complex professional operation and knowledge skills are not needed, the operation is simplified, resources are saved, and the detection cost is reduced.

Fig. 2 is a flow chart illustrating another method for detecting rf hardware according to an exemplary embodiment, where the method further includes:

and 105, configuring the receiving signal frequency, the receiving signal strength, the receiving data type, the output port and the switch of the radio frequency signal of the signal source instrument to realize the configured signal source instrument.

Illustratively, The received signal frequency may be any frequency within The 3GPP (english: The 3rd generation partnership project, chinese: third generation partnership project), and The received data type may be a single carrier signal sent by The signal source instrument, or may be a certain modulation signal in a certain system loaded by The signal source instrument.

Fig. 3 is a flowchart illustrating a method for detecting radio frequency hardware according to an exemplary embodiment, where as shown in fig. 3, after the configured signal source meter is connected to the first detection port of the radio frequency hardware, the configuring of the radio frequency hardware by using software programming in step 101 includes the following steps:

step 1011, configuring the starting system parameters of the radio frequency hardware.

The starting system parameter comprises at least one of power supply of radio frequency hardware, clock, software address mapping, hardware address mapping, data channel, bus control and signal control corresponding to a pin.

Generally, a radio frequency hardware daughter board of a path to be tested is installed on an EVB (Edge virtual bridging, chinese) or FPGA (Field Programmable Gate Array, chinese) platform, a communication system can be functionally divided into a baseband part and a radio frequency part, and a precondition for testing the radio frequency hardware path is that the whole system can normally operate, so that it is necessary to configure parameters of a start-up system first. In addition, if a baseband platform and a baseband version exist, the software configuration at the moment is to directly load the baseband version, and the baseband can work.

Step 1012, initializing the rf hardware that completes the configuration of the startup system parameters.
