Description

Technical Field

[0001] This application relates to the field of electronic signal technology, and in particular to signal generation methods, apparatus and computer-readable storage media. Background Technology

[0002] In many technical fields such as radio frequency and microwave communication, precision testing and measurement, and electronic equipment debugging, general-purpose signal sources are core basic testing instruments. The spectral purity, dynamic range, and signal quality of their output signals directly determine the accuracy of various test results and are also a key prerequisite for ensuring the stable operation of various electronic systems. The market demand for miniaturized, lightweight, low-cost, and high-performance signal source equipment is continuously increasing.

[0003] Currently, mainstream general-purpose signal source products in the industry generally adopt the mainstream design scheme of outputting a high-frequency fundamental wave signal and then performing frequency division. In order to meet the high dynamic range output requirements of the equipment, this traditional structure also requires the addition of a large-volume, high-specification, and heavy-duty shielding protection structure. The working method of obtaining the target frequency signal by frequency division of the high-frequency fundamental wave results in a large amount of idle and unnecessary loss of the original high-frequency fundamental wave signal resources, low signal utilization efficiency, and difficulty in optimizing the resource utilization of the overall circuit architecture.

[0004] Meanwhile, the heavy shielding components configured to suppress stray signals and electromagnetic interference to improve dynamic range not only significantly increase the overall size and weight of the signal source device, but also substantially increase the overall material costs, assembly costs, and R&D and production costs. The inherent defects of these two types of traditional designs severely restrict the development of signal source devices towards miniaturization, portability, and low cost, and also fail to meet the diverse practical application needs of today's portable field testing and lightweight integrated deployments. The industry urgently needs a new signal source architecture solution to address these existing technical pain points. Summary of the Invention

[0005] This application provides a signal generation method, apparatus, and computer-readable storage medium, which can improve the signal utilization efficiency of a signal source and reduce the material cost of the signal source.

[0006] To achieve the above objectives, this application adopts the following technical solution: In a first aspect, a signal generation method is provided, comprising: acquiring the maximum attenuation amplitude value of a signal amplitude attenuator in a signal source, the signal amplitude attenuation value of a target signal, the target signal frequency of the target signal, and the fundamental signal frequency range of a fundamental signal generation device in the signal source; the signal source further comprises a frequency divider connected to the fundamental signal generation device and an RF signal output pole connected to the frequency divider, the RF signal output pole being further connected to the signal amplitude attenuator; determining the frequency distribution result of the target signal frequency; the frequency distribution result is used to indicate that the target signal frequency is less than the lower limit of the fundamental signal frequency range, or that the target signal frequency is within the fundamental signal frequency range; based on the frequency distribution result, determining the target fundamental signal frequency according to the target signal frequency and multiple division coefficients of the frequency divider; determining the target operating mode among multiple operating modes of the RF signal output pole according to the maximum attenuation amplitude value and the signal amplitude attenuation value; the multiple operating modes include mute output and non-mute output; and outputting the target signal according to the target fundamental signal frequency and the target operating mode of the RF signal output pole.

[0007] Based on this scheme, key parameters such as the fundamental signal frequency range, target signal frequency, maximum attenuation amplitude of the attenuator, and the actual required signal amplitude attenuation value are first collected. By determining the frequency range of the target signal, different division coefficients of the frequency divider are flexibly matched to accurately select the appropriate target fundamental signal frequency. This abandons the traditional design approach of simply using ultra-high frequency fundamental signals for frequency division output, greatly reducing the idle loss of the fundamental signal and significantly improving the utilization efficiency of the fundamental signal. At the same time, the target operating modes corresponding to the mute output and non-mute output of the RF signal output terminal are reasonably selected according to the attenuation parameters. By adjusting the signal amplitude attenuation, the output signal quality is optimized, which can effectively suppress electromagnetic spurious interference. Without the need for a large, heavy, and thick shielding protection structure, the signal output can be guaranteed to have excellent high dynamic range performance. This solution significantly simplifies the overall hardware structure of the signal source, reduces redundant components, effectively reduces the overall size and weight of the device, and lowers the costs of material procurement, assembly, and manufacturing. It fundamentally overcomes the technical obstacles that traditional signal sources face in the process of miniaturization, lightweighting, and cost reduction, and can fully meet the needs of various practical application scenarios such as on-site portable testing and device integration.

The industry urgently needs a new signal source architecture solution to address these existing technical pain points.

[0035] To address the aforementioned problems, this application provides a signal generation method. The method includes: acquiring the maximum attenuation amplitude value of a signal amplitude attenuator in a signal source, the signal amplitude attenuation value of a target signal, the target signal frequency of the target signal, and the fundamental signal frequency range of a fundamental signal generation device in the signal source; the signal source further includes a frequency divider connected to the fundamental signal generation device and an RF signal output terminal connected to the frequency divider, the RF signal output terminal also being connected to the signal amplitude attenuator; determining the frequency distribution result of the target signal frequency; the frequency distribution result is used to indicate that the target signal frequency is less than the lower limit of the fundamental signal frequency range, or that the target signal frequency is within the fundamental signal frequency range; based on the frequency distribution result, determining the target fundamental signal frequency according to the target signal frequency and multiple division coefficients of the frequency divider; determining the target operating mode among multiple operating modes of the RF signal output terminal according to the maximum attenuation amplitude value and the signal amplitude attenuation value; the multiple operating modes include mute output and non-mute output; and outputting the target signal according to the target fundamental signal frequency and the target operating mode of the RF signal output terminal.

[0037] Figure 1 This is a schematic diagram of the architecture of a signal generation system provided in this application. The technical solutions of the embodiments of this application can be applied to... Figure 1 The signal generation system shown is as follows: Figure 1 As shown, the signal generation system 10 includes a signal generation device 11 and an electronic device 12.

[0038] The signal generation system 10 can be deployed in the processor of the signal source. In this case, the signal generation device 11 can be the processing core of the processor of the signal source, and the electronic device 12 can be the I / O interface of the processor.

[0039] The signal source is used to generate a signal with an extremely high amplitude output adjustment range and excellent amplitude control accuracy.

[0040] The signal source includes a fundamental signal generator, a frequency divider connected to the fundamental signal generator, an RF signal output pole connected to the frequency divider, and a signal amplitude attenuator connected to the RF signal output pole.

[0041] The fundamental wave signal generator is used to generate the fundamental wave signal. The fundamental wave signal is the original, lowest-order sine wave frequency directly generated by the fundamental wave signal generator without nonlinear transformation operations such as frequency doubling. It is also the signal with the strongest output signal energy in the phase-locked loop of the frequency synthesizer.

[0042] A frequency divider is used to transform the input fundamental signal according to a set division ratio. It is a core functional device in a frequency synthesizer that enables frequency control, frequency division, and phase comparison.

[0043] The RF signal output electrode has two operating modes: mute mode and non-mute mode. In mute mode, the built-in control logic and output path control circuit significantly attenuate the RF signal output of the frequency synthesizer, so that the RF signal output electrode is maintained in a low-noise state with no effective RF signal output.

[0044] A signal amplitude attenuator is an attenuator that connects multiple attenuators in series to form an attenuation value.

[0045] The signal generating device 11 is directly or indirectly connected to the electronic device 12. This connection can be wired or wireless, and this embodiment of the application does not limit the connection.

[0046] The signal generating device 11 and the electronic device 12 can exchange data.

[0047] It should be noted that the signal generating device 11 and the electronic device 12 can be independent devices or integrated into the same device; this application does not make any specific limitation in this regard.

[0048] When the signal generating device 11 and the electronic device 12 are integrated into the same device, the communication method between the signal generating device 11 and the electronic device 12 is the same as the communication method between internal modules of the device. In this case, the communication process between the two is the same as that between the signal generating device 11 and the electronic device 12 when they are independent of each other.

[0049] In the following embodiments provided in this application, the signal generating device 11 and the electronic device 12 are described as being configured independently of each other.

[0050] In practical applications, the signal generation method provided in this application embodiment can be applied to the signal generation device 11, or to the devices included in the signal generation device 11.

[0051] The signal generation method provided in this application embodiment will be described below with reference to the accompanying drawings, taking the application of the signal generation method to the signal generation device 11 as an example.

[0052] Figure 2 A flowchart illustrating a signal generation method provided in this application is shown below. Figure 2 As shown, the method includes the following steps: S201, The signal generating device acquires the maximum attenuation value of the signal amplitude attenuator in the signal source, the signal amplitude attenuation value of the target signal, the target signal frequency of the target signal, and the fundamental signal frequency range of the fundamental signal generating device in the signal source.

[0053] The signal source also includes a frequency divider connected to the fundamental signal generator, an RF signal output pole connected to the frequency divider, and the RF signal output pole is also connected to a signal amplitude attenuator.

[0054] As one possible implementation method, combined with Figure 1 The signal generating device sends a first request message to the electronic device; the first request message is used to request the maximum attenuation value of the signal amplitude attenuator in the signal source, the signal amplitude attenuation value of the target signal, the target signal frequency of the target signal, and the fundamental signal frequency range of the fundamental signal generating device in the signal source.

[0055] Accordingly, the electronic device receives the first request information, generates and sends a first response message to the signal generating device. The first response message includes the maximum attenuation value of the signal amplitude attenuator in the signal source, the signal amplitude attenuation value of the target signal, the target signal frequency of the target signal, and the fundamental signal frequency range of the fundamental signal generating device in the signal source.

[0056] Accordingly, the signal generating device receives the first response message and obtains from the first response message the maximum attenuation value of the signal amplitude attenuator in the signal source, the signal amplitude attenuation value of the target signal, the target signal frequency of the target signal, and the fundamental signal frequency range of the fundamental signal generating device in the signal source.

[0057] S202, The signal generation device determines the frequency distribution result of the target signal frequency.

[0058] The frequency distribution result is used to indicate that the target signal frequency is less than the lower limit of the fundamental signal frequency range, or that the target signal frequency is within the fundamental signal frequency range.

[0059] As one possible implementation, the signal generating device determines whether the frequency of the target signal is less than the lower limit of the fundamental signal frequency range.

[0060] If the target signal frequency is less than the lower limit of the fundamental signal frequency range, the signal generating device determines the frequency distribution result to indicate that the target signal frequency is less than the lower limit of the fundamental signal frequency range. If the target signal frequency is greater than or equal to the lower limit of the fundamental signal frequency range, the signal generating device determines whether the target signal frequency is within the fundamental signal frequency range. If the target signal frequency is within the range of the fundamental signal frequency, the signal generating device determines the frequency distribution result to indicate that the target signal frequency is within the range of the fundamental signal frequency.

[0061] If the target signal frequency is outside the range of the fundamental signal frequency, the signal generating device generates an indication message indicating that the target signal frequency does not meet the requirements.

[0062] S203. The signal generation device determines the target fundamental signal frequency based on the frequency distribution results, according to the target signal frequency and multiple frequency division coefficients of the frequency divider.

[0063] It should be noted that multiple frequency division coefficients can be multiples of 2. For example, multiple frequency division coefficients can be 2, 4, 6, 8, 10, etc. This application does not impose specific restrictions on this.

[0064] As one possible implementation, when the frequency distribution result indicates that the target signal frequency is less than the lower limit of the fundamental signal frequency range, the signal generating device determines a first frequency division coefficient among multiple frequency division coefficients; the product of the first frequency division coefficient and the target signal frequency is within the fundamental signal frequency range, the product of the second frequency division coefficient and the target signal frequency is outside the fundamental signal frequency range, and the second frequency division coefficient is a frequency division coefficient among multiple frequency division coefficients that is less than the target frequency division coefficient; the product of the target frequency division coefficient and the first signal frequency is taken as the target fundamental signal frequency.

[0065] As an example, suppose the fundamental frequency range of the fundamental signal generating device in the signal source is 1000MHz to 3000MHz, the frequency divider has multiple selectable frequency division coefficients such as 2, 4, 6, and 8, and the target signal frequency to be output is 300MHz, which is less than the lower limit of the fundamental signal frequency range of 1000MHz.

[0066] Each frequency division coefficient is multiplied by 300MHz sequentially for evaluation: the result of multiplying by frequency division coefficient 2 is 600MHz, which is outside the fundamental frequency range; the result of multiplying by frequency division coefficient 4 is 1200MHz, which falls within the fundamental frequency range of 1000MHz to 3000MHz; therefore, 4 is determined as the first frequency division coefficient and 2 as the second frequency division coefficient. Finally, the target signal frequency of 300MHz is multiplied by the first frequency division coefficient 4 to obtain 1200MHz, which is taken as the target fundamental signal frequency.

[0067] Based on this possible implementation method, when the target signal frequency is lower than the lower limit of the fundamental signal frequency range, by comparing the product results of different frequency division coefficients and the target signal frequency, the optimal first frequency division coefficient that falls within the fundamental signal frequency range is accurately selected. Invalid frequency division coefficients with small values ​​and calculation results exceeding the frequency range are excluded. In this way, the appropriate target fundamental signal frequency is accurately determined. It can strictly rely on the inherent fundamental output frequency band of the equipment to complete the generation of low-frequency target signals, without deliberately selecting ultra-high fundamental frequencies far exceeding actual needs for frequency division. This effectively avoids the problem of a large waste of fundamental signal resources. The selection logic of frequency division ratio is clear and rigorous, which can ensure that the output signal frequency after frequency division is accurate. At the same time, it adapts to the inherent hardware frequency output capability of the signal source. It can achieve stable low-frequency signal output without modifying the hardware parameters of the fundamental generation unit, further optimizing the signal generation process and reducing the difficulty of signal matching and equipment operation losses.

[0068] As another possible implementation, when the frequency distribution result indicates that the target signal frequency is within the range of the fundamental signal frequency, the signal generating device divides the target signal frequency by 3 to obtain the second signal frequency; determines the third frequency division coefficient among multiple frequency division coefficients; the product of the third frequency division coefficient and the second signal frequency is within the range of the fundamental signal frequency, the product of the fourth frequency division coefficient and the second signal frequency is outside the range of the fundamental signal frequency, and the fourth frequency division coefficient is a frequency division coefficient smaller than the third frequency division coefficient among multiple frequency division coefficients; and takes the product of the second frequency division coefficient and the second signal frequency as the target fundamental signal frequency.

[0069] As an example, suppose the fundamental frequency range of the fundamental signal generator is 1000MHz to 3000MHz, and the frequency divider is configured with multiple division coefficients such as 2, 4, 6, and 8. The target output signal frequency is 1500MHz, which is within the fundamental frequency range. First, divide the target signal frequency 1500MHz by 3 to obtain the second signal frequency 500MHz. Then, compare the product of each division coefficient and 500MHz. The result calculated by division coefficient 2 does not fall within the 1000MHz to 3000MHz range, so it is determined to be the fourth division coefficient. The third division coefficient is then selected as 4. The product of the two is 2000MHz, which is within the fundamental frequency range. Finally, based on this matching relationship, the target fundamental signal frequency is determined to be 2000MHz.

[0070] Based on this possible implementation, when the target signal frequency is within the range of the fundamental signal frequency, the target signal frequency is first divided and converted to obtain the second signal frequency. Then, the optimal third frequency division coefficient is selected through the frequency division coefficient screening rule to accurately match and obtain the target fundamental signal frequency that meets the frequency band requirements. This breaks the single output mode of directly using the target frequency as the fundamental signal, reasonably optimizes the fundamental signal selection logic, and ensures that the fundamental signal generation unit always works within the optimal operating frequency band. This effectively improves the signal output stability and spectral purity, further reduces spurious components during signal transmission, and continues the frequency division adaptation and selection approach. It unifies the overall signal generation and control logic, and can flexibly adjust the signal within the frequency band without changing the hardware structure, further improving the overall working performance and frequency adaptability of the signal source.

[0071] S204. The signal generation device determines the target operating mode among multiple operating modes of the RF signal output pole based on the maximum attenuation value and the signal amplitude attenuation value.

[0072] Among them, there are multiple operating modes, including silent output and non-silent output.

[0073] As one possible implementation, the signal generating device determines whether the maximum attenuation amplitude value is less than the signal amplitude attenuation value; if the maximum attenuation amplitude value is greater than or equal to the signal amplitude attenuation value, it determines that the target operating mode of the RF signal output pole is non-mute output; if the maximum attenuation amplitude value is less than the signal amplitude attenuation value, it determines that the target operating mode of the RF signal output pole is mute output.

[0074] As an example, if the maximum attenuation value of the signal amplitude attenuator is 60dB, and the actual required signal amplitude attenuation value of the target signal is 40dB under the first operating condition, the maximum attenuation value is greater than the required signal amplitude attenuation value. Therefore, it is determined that the normal attenuation adjustment condition is met, and the target operating mode of the RF signal output pole is set to non-silent output mode. The signal output can be completed by relying on the normal amplitude adjustment of the attenuator.

[0075] In the second operating condition, the actual required signal amplitude attenuation value of the target signal is 75dB. This value exceeds the maximum attenuation range of 60dB of the attenuator. The maximum attenuation value is less than the required signal amplitude attenuation value, and the attenuation requirement cannot be achieved by conventional attenuation methods. Therefore, the target operating mode among the multiple operating modes of the RF signal output pole is determined to be the silent output mode, and the deep signal attenuation control is achieved by relying on the silent output.

[0076] Based on this possible implementation, by comparing the maximum attenuation amplitude of the attenuator with the actual required signal amplitude attenuation, the system automatically matches the non-silent output and silent output modes corresponding to the RF signal output pole based on the judgment result. This can accurately adapt to signal output scenarios with different amplitude attenuation requirements. Within the normal attenuation range, non-silent output is used to ensure normal and stable signal output. When the maximum attenuation range is exceeded, silent output is enabled to achieve deep attenuation control. This effectively optimizes the dynamic range of the output signal without the need for additional attenuation circuits and heavy shielding structures, simplifies the signal amplitude control logic, improves the adaptability of signal amplitude adjustment and output signal quality, reduces hardware expansion costs, and further improves the overall output control system of the signal source.

[0077] S205. The signal generation device outputs the target signal according to the target fundamental frequency and the target operating mode of the RF signal output pole.

[0078] As one possible implementation, when the frequency distribution result indicates that the target signal frequency is less than the lower limit of the fundamental signal frequency range, the signal generating device is configured to operate in the target mode at the RF signal output pole; the fundamental signal generating device is controlled to generate the target fundamental signal; the frequency of the target fundamental signal is the target fundamental signal frequency; the frequency divider is controlled to divide the target fundamental signal based on the first frequency division coefficient to obtain the first signal; the first signal is output through the RF signal output pole and the signal amplitude attenuator to obtain the target signal.

[0079] As an example, if the fundamental frequency range is 1000MHz~3000MHz, and the required target signal frequency is 300MHz, which is less than the lower limit of the fundamental frequency, the first frequency division factor is determined to be 4, corresponding to a target fundamental frequency of 1200MHz; the maximum attenuation amplitude of the attenuator is set to 60dB, and the required signal amplitude attenuation value is 40dB, so the target working mode is determined to be non-silent output.

[0080] First, the RF signal output is configured to non-mute output mode, and the fundamental signal generator is controlled to output a 1200MHz target fundamental signal. The frequency divider divides the fundamental signal according to the first division factor of 4 to obtain a first signal with a frequency of 300MHz. Then, the first signal is passed through the RF signal output and the signal amplitude attenuator to complete the amplitude adjustment and output stably, finally obtaining the target signal that meets the frequency and amplitude requirements.

[0081] Based on this possible implementation method, in application scenarios where the target signal frequency is lower than the lower limit of the fundamental signal frequency, the working mode of the RF output terminal is preset and configured first, and then the fundamental signal generation, fixed coefficient frequency division processing, and amplitude attenuation control are completed in an orderly manner. The overall signal generation and output process is clear in hierarchy and logically coherent, and can accurately output the target signal that meets the frequency and amplitude indicators. By relying on the established frequency division rules and output working mode, the accuracy of the low-frequency signal output frequency is guaranteed, and the signal amplitude can be controlled in compliance with regulations at the same time. No additional frequency conditioning circuits and heavy shielding components are required throughout the process, which effectively simplifies the low-frequency signal output control process, improves the stability and consistency of the signal output, reduces spurious interference in the signal output process, and further ensures the overall miniaturization and low cost of the signal source.

[0082] As another possible implementation, when the frequency distribution results indicate that the target signal frequency is within the range of the fundamental signal frequency, the signal generation device is configured to operate in the target mode at the RF signal output pole; the fundamental signal generation device is controlled to generate the target fundamental signal; the frequency of the target fundamental signal is the target fundamental signal frequency; the frequency divider is controlled to divide the target fundamental signal based on the third frequency division coefficient to obtain the second signal; the frequency of the second signal is tripled to obtain the third signal; the third signal is output through the RF signal output pole and the signal amplitude attenuator to obtain the target signal.

[0083] As an example, suppose the fundamental frequency range is 1300MHz to 2800MHz, and the desired target signal frequency is set to 1800MHz, which falls within the fundamental frequency range.

[0084] First, divide the target signal frequency by 3 to obtain the second signal frequency of 600MHz; then, select and determine the third frequency division coefficient as 4, and calculate the target fundamental signal frequency of 2400MHz.

[0085] The preset maximum attenuation of the signal amplitude attenuator is 70dB, and the required attenuation value is 50dB. Therefore, the working mode of the RF signal output is determined to be non-silent output.

[0086] First, configure the RF signal output to non-mute output mode, control the fundamental signal generator to output a target fundamental signal of 2400MHz, and divide the frequency by the frequency divider according to the third frequency division factor of 4 to obtain a second signal with a frequency of 600MHz; then, multiply the second signal by 3 to obtain a third signal with a frequency of 1800MHz, and finally output the third signal after amplitude adjustment by the RF signal output and the signal amplitude attenuator, thus obtaining the target signal that meets the frequency and amplitude requirements.

[0087] Optionally, the frequency divider and the RF signal output in the signal source can also be connected through a frequency multiplier circuit to multiply the signal.

[0088] Based on this possible implementation, when the target signal frequency is within the fundamental signal frequency range, the target signal is generated through a combination of frequency conversion, first frequency division and then third harmonic. Combined with a pre-configured RF output operating mode, the entire process of fundamental signal generation, frequency division, harmonic conversion, and amplitude attenuation output is completed in an orderly manner. This allows the fundamental signal generator to operate in the preferred operating frequency band for extended periods, effectively improving the spectral purity of the output signal and suppressing spurious harmonics. Simultaneously, by adaptively selecting the output operating mode using attenuation parameters, precise amplitude control is achieved. High dynamic range signal output can be guaranteed without relying on large, heavy shielding structures. The overall control process is standardized and unified, enabling flexible signal generation within the frequency band without modifying the hardware circuit structure. This effectively reduces the complexity of the equipment structure and manufacturing costs, facilitating miniaturization and lightweight design of the signal source, and significantly improving the equipment's frequency adaptability and versatility in practical applications.

[0089] Based on S201-S205, key parameters such as the fundamental signal frequency range, target signal frequency, maximum attenuation amplitude of the attenuator, and the actual required signal amplitude attenuation value are first collected. By determining the frequency range of the target signal, different division coefficients of the frequency divider are flexibly matched to accurately select the appropriate target fundamental signal frequency. This abandons the traditional design approach of simply using ultra-high frequency fundamental signals for frequency division output, greatly reducing the idle loss of the fundamental signal and significantly improving the utilization efficiency of the fundamental signal. At the same time, the target operating modes corresponding to the mute output and non-mute output of the RF signal output terminal are reasonably selected according to the attenuation parameters. By adjusting the signal amplitude attenuation, the output signal quality is optimized, which can effectively suppress electromagnetic spurious interference. Without the need for a large, heavy, and thick shielding protection structure, the signal output can be guaranteed to have excellent high dynamic range performance. This solution significantly simplifies the overall hardware structure of the signal source, reduces redundant components, effectively reduces the overall size and weight of the device, and lowers the costs of material procurement, assembly, and manufacturing. It fundamentally overcomes the technical obstacles that traditional signal sources face in the process of miniaturization, lightweighting, and cost reduction, and can fully meet the needs of various practical application scenarios such as on-site portable testing and device integration.
