[0067] Figure 3 It is a schematic flowchart of a radio frequency performance test method shown in the second embodiment of the present disclosure, as Figure 3 shown, the method includes:

[0068] S301: Obtain the first test case information of the device under test, where the first test case information corresponds to the first radio frequency test type, and the device under test at least includes: a radio frequency front end RFFE.

[0069] S302: Determine the path information and signal configuration information required for configuring test cases for the first radio frequency test type according to the first test case information.

[0070] S303: Configure the loop related to the radio frequency front end (RFFE) according to the path information, and configure the parameters of the radio frequency front end (RFFE) according to the signal configuration information. After configuration, the radio frequency front end (RFFE) meets the test conditions of the first radio frequency test type, and the device under test transmits or receives signals based on the radio frequency front end (RFFE).

[0071] For the descriptions of S301 - S303, please refer to the above embodiments for details and will not be elaborated here.

[0072] S304: Provide the first test case information to the instrument platform. The instrument platform executes the test cases of the TX test based on the first test case information, so that the spectrum analyzer in the instrument platform receives the transmitted signal of the device under test and performs tests based on the received transmitted signal to obtain radio frequency test data.

[0073] In the embodiments of the present disclosure, the first radio frequency test type may specifically be the TX test.

[0074] Optionally, in some embodiments, determine the instrument interface information according to the first test case information. The instrument interface information is used to describe the interface configuration of each device in the instrument platform. The devices in the instrument platform include: a signal source and a spectrum analyzer. Then, configure the interfaces of each device in the instrument platform according to the instrument interface information.

[0075] In the embodiments of the present disclosure, after configuring the loop related to the radio frequency front end (RFFE) according to the path information and configuring the parameters of the radio frequency front end (RFFE) according to the signal configuration information, the first test case information may be provided to the instrument platform. The instrument platform executes the test cases of the TX test based on the first test case information, so that the spectrum analyzer in the instrument platform receives the transmitted signal of the device under test and performs tests based on the received transmitted signal to obtain radio frequency test data.

[0076] That is to say, in the embodiments of the present disclosure, refer to Figure 4A , Figure 4A is a schematic diagram of the test process of the test case of the TX test proposed according to an embodiment of the present disclosure, that is, it may be a tool (refer to the above Figure 2A, the tool is integrated in the PC) obtains the test cases for the TX test during the initial test phase. At the same time, the device under test is powered on, and the General-Purpose Input / Output (GPIO) ports of the device under test will emit signals. The corresponding Databin file is downloaded, and the corresponding path (where path refers to the path related to testing or measurement) and RFFE are configured. Keep long hair during this phase, and perform initialization processing on the instrument platform. Then, the tool sends a trigger signal to the device under test and the instrument platform, and at the same time provides the first test case information to the instrument platform. The spectrum analyzer in the instrument platform receives the emitted signal and executes the test test case according to the information configured by the tool.

[0077] During the TX test, the tool controls the signal source to generate waveforms, the device under test captures data, and the algorithm module is called to analyze and report the test results, which include TX conventional test items (such as power, ACLR, EVM, etc.) and the scanning scheme for TX spurious signals (analyzing spurious indexes such as the DC component of the signal, the DC component, second / third harmonic distortion, third / fifth order intermodulation products, harmonics, etc.).

[0078] Optionally, in some embodiments, frequency scanning can also be performed on the transmitted signal or the received signal to obtain the frequency scanning result.

[0079] Optionally, in some embodiments, performing frequency scanning on the transmitted signal or the received signal to obtain the frequency scanning result may be to obtain a list of spectral peaks of the transmitted signal or the received signal, obtain information on the first spurious component located on the left side of the carrier frequency point from the list of spectral peaks; obtain information on the second spurious component located on the right side of the carrier frequency point from the list of spectral peaks, obtain information on the spurious frequency points of the image frequency and the local oscillator from the list of spectral peaks, determine the first integrated power corresponding to at least one first reference Mark point according to the information on the first spurious component, and use at least one first integrated power as the first component power of the first spurious component. According to the information on the second spurious component, determine the second integrated power corresponding to at least one second reference Mark point, and use at least one second integrated power as the second component power of the second spurious component. According to the information on the first spurious component and the information on the second spurious component, determine the spurious component type corresponding to each frequency component in the list of spectral peaks.

[0080] Among them, the first component power of the first spurious component, the first spurious type, the second component power of the second spurious component and the second spurious type, and the spurious component type corresponding to each frequency component in the list of spectral peaks are jointly used as the frequency scanning result.

[0081] Among them, radio frequency spurious emission (RF TX Spurious Emission) / in-band emission (Inband Emission) is an important test index of 3GPP. It is mainly used to detect the in-band / out-of-band indexes of the device under test and avoid unnecessary spurs so as not to interfere with this device or other devices. Since spurs are caused by various non-linear factors, such as harmonics, intermodulation or local oscillator leakage (LO Leakage), the identification of these spur components is of great significance for the research of radio frequency systems. However, the test schemes for signaling and production do not identify spur components separately. Therefore, this scheme introduces a spectrum identification scheme, which is based on the principle that different spurs fall in different positions in the frequency band and is used for TX Spur identification. See Figure 4B , Figure 4B is a schematic diagram of in-band and out-of-band TX spurs proposed according to an embodiment of the present disclosure. Among them, the definitions of each frequency component are shown in Table 1:

[0082] Table 1

[0083] Marker Point Frequency Component Definition M1 LO-BB IMG / IRR M2 LO LO / DC M3 LO+BB Carrier M4 LO-2BB IM5 M5 LO+3BB HD3 M6 LO-3BB CIM3 M7 LO+2BB HD2 M8 LO+5BB CIM5

[0084] In the embodiment of the present disclosure, the scheme for Spur measurement and separation is as follows:

[0085] (1) In the normal transmission state of the device under test, the spectrum mode of the spectrum analyzer is set as follows: the center frequency is set to LO (low frequency point), the marker frequency is set to LO plus 0.45 times the bandwidth (BW), that is, LO + 0.45BW, and the scan range (Span) is set to 14 times the bandwidth, that is, 14BW. In the case of a bandwidth (for example, BW = 1 MHz), the marker function is set to band power (BandPower). At this time, the functional power (Func Power) of this reference point (Marker) read is the carrier power (CarrierPower).

[0086] (2) Obtain the spectrum peak list of the transmitted signal or received signal, that is, retrieve the spectrum peak list (Peaklist), and obtain the first spur component located on the left side of the carrier frequency point from it, and set the information of the first spur component. The information of the first spur component is shown in Table 2:

[0087] Table 2

[0088] Parameter Meaning Value Number of Peaks Number of Scanned Peak Points 5 Left Limit Starting Point of Scanned Spectrum LO-3BW Right Limit Ending Point of Scanned Spectrum LO-3 / 4BW

[0089] Then, obtain the second spur component located on the right side of the carrier frequency point from the spectrum peak list (Peak list), and set the information of the second spur component. The information of the second spur component is shown in Table 3:

[0090] Table 3

[0091] Parameter Meaning Value Number of Peaks Number of Scanned Peak Points 5 Left Limit Starting Point of Scanned Spectrum LO+3BW Right Limit Ending Point of Scanned Spectrum LO+3 / 4BW

[0092] Then, obtain the information of the image frequency and the spurious frequency points of the local oscillator from the Peak list. The information of the image frequency and the spurious frequency points of the local oscillator is shown in Table 4:

[0093] Table 4

[0094]

[0095]

[0096] (3) After determining the information of the first spurious component in Table 2, Mark and Mark power frequency band = 1 MHz can be set centered on each value (frequency point) in Table 2, and the integrated power of each determined first Mark point is used as the first component power (Spur_Pow) of the first spurious component.

[0097] After determining the information of the second spurious component in Table 3, Mark and Mark power frequency band = 1 MHz can be set centered on each value (frequency point) in Table 3, and the integrated power of each determined second Mark point is used as the second component power (Spur_Pow) of the second spurious component.

[0098] (4) According to the information of the first spurious component and the information of the second spurious component, determine the spurious component type (spur component) corresponding to each frequency component in the spectrum peak list.

[0099] That is to say, it can be to traverse Table 2 and Table 3, and when it is determined that the Mark point satisfies (LO - BW * 0.45) - eps ≤ freq ≤ (LO - BW * 0.45) + eps (where eps is the judgment protection bandwidth, indicating that a partial frequency deviation of the frequency is allowed), it is determined that the spurious component type corresponding to the Mark point belongs to the image frequency (Image Frequency, IMG) component. When it is determined that the Mark point does not satisfy (LO - BW * 0.45) - eps ≤ freq ≤ (LO - BW * 0.45) + eps, it is determined that the spurious component type corresponding to the Mark point is a common spurious.

[0100] It should be noted that the parameters under the frequency components in Table 1 are the non - linear frequency point information publicly disclosed in the 3GPP standard document, that is, the meaning indicated by each parameter belongs to the common knowledge in the art, and the present disclosure will not elaborate and list its meaning.

[0101] S305: Receive the RF test data fed back by the instrument platform.

[0102] In the embodiments of the present disclosure, referring to the above Figure 4A , after the instrument platform executes the test case of the TX test based on the first test case information to obtain the test data and test results, the test data and test results can be reported to the tool. The tool will process the test data, write the test data into the test report, then detect whether all the test cases of the TX test have been executed. When it is determined that the test cases have not been executed completely, the tool controls the device under test to emit signals again to load the next test case. When it is determined that all the test cases have been executed, the test process of the test cases of the TX test is ended.

[0103] S306: Determine the radio frequency performance result of the device under test according to the radio frequency test data.

[0104] In the embodiments of the present disclosure, the radio frequency performance result of the device under test further includes: the ratio of the component of the spurious component to the noise (Spur to Noise Ratio).

[0105] In the embodiments of the present disclosure, the RX loop spurs from LO Leakage, TX Leakage / TXNoise, and Clock Leakage will directly affect the receiver sensitivity performance and anti-interference performance. Therefore, it is also very important to capture the receiver spurs of the RX loop. Since the expected returned data is not the absolute power of the spurs (the increase in the background noise will also cause an increase in the spurs, and different gain states of the loop will bring different background noises, resulting in the inability to analyze the spur intensities in different gain states in parallel), thus, it is very meaningful to determine the ratio of the component of the spurious component to the noise (Spur to Noise Ratio).

[0106] Before calculating the Spur to Noise Ratio, it is first necessary to follow the RX test process. Use a signal source to inject a radio frequency signal into the DUT through the antenna port, and then control the device under test to obtain the in-phase and quadrature (IQ) data of the captured data through the serial port. This data is usually a binary file.

[0107] Optionally, in some embodiments, according to the RF test data and the frequency sweep result, the RF performance result of the device under test can be determined. Specifically, the spectral power density of the transmitted signal or the received signal can be obtained according to the RF test data. Then, based on the spectral power density, the number of frequency peak points and the minimum peak interval can be determined. According to the number of frequency peak points and the minimum peak interval, the signal amplitude and frequency of the spurious signal can be determined. Based on the spectral power density, the signal amplitude and frequency of the spurious signal, the background noise information can be determined. According to the first component power of the first spurious component and the background noise information in the frequency sweep result, the ratio of the first component of the first spurious component to the noise can be determined. According to the second component power of the second spurious component and the background noise information in the frequency sweep result, the ratio of the second component of the second spurious component to the noise can be determined. Herein, the ratio of the first component to the noise and the ratio of the second component to the noise are used as the RF performance results.

[0108] In the embodiments of the present disclosure, the calculation process of the Spur to Noise Ratio includes:

[0109] (1) According to the RF test data, obtain the spectral power density of the transmitted signal or the received signal.

[0110] That is, it can be the power spectral density (PSD) obtained after performing a fast Fourier transform (FFT) on the RF test data.

[0111] (2) According to the spectral power density, determine the number of frequency peak points and the minimum peak interval.

[0112] In an example of the present disclosure, the number of frequency peak points (N peaks) and the minimum peak interval (Min Peak Distance) can be determined according to a preset function. Exemplarily, the preset function includes the find peak function.

[0113] Among them, N peaks is the number of index peak points, and the user can customize the number of points to be printed.

[0114] Among them, Min Peak Distance is the minimum interval between peaks, and this interval can be preset as needed to prevent the spectral uplift peaks around some spurs from being misdetected.

[0115] (3) According to the number of frequency peak points and the minimum peak interval, determine the signal amplitude and frequency of the spurious signal.

[0116] In the embodiments of the present disclosure, after obtaining the spectral power density of the transmitted signal or the received signal based on the radio frequency test data, and then determining the number of frequency peak points and the minimum peak interval according to the spectral power density, the signal amplitude and frequency of the spurious signal can be read back according to the number of frequency peak points and the minimum peak interval.

[0117] (4) Determine the background noise information according to the spectral power density, the signal amplitude and frequency of the spurious signal.

[0118] That is to say, in the embodiments of the present disclosure, the useful signal amplitude points around the useful signal frequency points can be removed according to the spectral power density, the signal amplitude and frequency of the spurious signal (in the scenario with signal input, the useful signal amplitude points do not need to be removed in the scenario without RX useful signals). After removing the useful signals, the remaining signals are integrated in the real domain and then converted to the logarithmic domain to obtain the background noise signal.

[0119] In the embodiments of the present disclosure, after determining the background noise signal, the signal power of the background noise signal can be determined, and the power of the background noise signal is used as the background noise information. Then, the spurious-to-noise ratio can be determined based on the background noise information. For details, please refer to the subsequent embodiments and will not be elaborated here.

[0120] (5) Determine the ratio of the first component of the first spurious component to the noise according to the first component power of the first spurious component in the frequency sweep result and the background noise information.

[0121] The ratio of the first component to the noise refers to the ratio between the first component power of the first spurious component and the power of the background noise signal.

[0122] That is to say, in the embodiments of the present disclosure, the ratio between the first component power and the power of the background noise signal can be determined, and this ratio is used as the ratio of the first component of the first spurious component to the noise.

[0123] (6) Determine the ratio of the second component of the second spurious component to the noise according to the second component power of the second spurious component in the frequency sweep result and the background noise information; the ratio of the first component to the noise and the ratio of the second component to the noise are used as the radio frequency performance results.

[0124] The ratio of the second component to the noise refers to the ratio between the second component power of the second spurious component and the power of the background noise signal.

[0125] That is to say, in the embodiments of the present disclosure, the ratio between the second component power and the power of the background noise signal can be determined, and this ratio is used as the ratio of the second component of the second spurious component to the noise.

[0126] In the embodiments of the present disclosure, after determining the ratio of the first component to the noise and the ratio of the second component to the noise, the ratio of the first component to the noise and the ratio of the second component to the noise can be jointly used as the radio frequency performance result. Thus, it is possible to solve the problem that different gain states of the loop will bring different background noises, resulting in the inability to analyze the Spur intensity of different gain states in parallel.

[0127] In the embodiments of the present disclosure, by obtaining the first test case information of the device under test, where the first test case information corresponds to the first radio frequency test type, the device under test at least includes: a radio frequency front end (RFFE). Then, according to the first test case information, determine the path information and signal configuration information required for configuring the test case of the first radio frequency test type. Configure the loop related to the RFFE according to the path information, and configure the parameters of the RFFE according to the signal configuration information. After configuration, the RFFE meets the test conditions of the first radio frequency test type. The device under test transmits or receives signals based on the RFFE, and provides the first test case information to the instrument platform. The instrument platform executes the test case of the TX test based on the first test case information, so that the spectrum analyzer in the instrument platform receives the transmitted signal of the device under test and performs tests based on the received transmitted signal to obtain radio frequency test data. Receive the radio frequency test data fed back by the instrument platform, and determine the radio frequency performance result of the device under test according to the radio frequency test data. Thus, the execution efficiency of the test case of the TX test can be improved, and further the automation test efficiency of the TX open-loop path can be improved, so as to effectively improve the radio frequency performance test efficiency and test accuracy.
