Detailed Description
In order to more clearly illustrate the technical solutions of the embodiments of the present disclosure, the drawings used in the description of the embodiments will be briefly described below. It is obvious that the drawings in the following description are only examples or embodiments of the present description, and that for a person skilled in the art, the present description can also be applied to other similar scenarios on the basis of these drawings without inventive effort. Unless otherwise apparent from the context, or otherwise indicated, like reference numbers in the figures refer to the same structure or operation.
It should be understood that "system", "device", "unit" and/or "module" as used herein is a method for distinguishing different components, elements, parts, portions or assemblies at different levels. However, other words may be substituted by other expressions if they accomplish the same purpose.
As used in this specification and the appended claims, the terms "a," "an," "the," and/or "the" are not intended to be inclusive in the singular, but rather are intended to be inclusive in the plural, unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that steps and elements are included which are explicitly identified, that the steps and elements do not form an exclusive list, and that a method or apparatus may include other steps or elements.
Flow charts are used in this description to illustrate operations performed by a system according to embodiments of the present description. It should be understood that the preceding or following operations are not necessarily performed in the exact order in which they are performed. Rather, the various steps may be processed in reverse order or simultaneously. Meanwhile, other operations may be added to the processes, or a certain step or several steps of operations may be removed from the processes.
Generally, a manual test method is adopted for testing the power amplifier. However, manual testing requires a tester to be skilled in instrument operation and has rich power amplifier testing experience, and the manual testing process is complicated. It is known that current power amplifiers have a plurality of inputs that can accept different types of input signals, such as digital signals, analog signals, optical signals, high definition signals, and the like. Each input terminal needs to be properly connected to the corresponding cable to receive the input signal. Assuming that an input receives only digital signals, the input can receive digital signals after being correctly connected to the corresponding cable connection. This input is connected to other unmatched cables and cannot receive signals. The detection of the power amplifier requires determining a plurality of property parameters such as signal-to-noise ratio, distortion degree and the like. During detection, different signals or signal combinations are required to be transmitted into the power amplifier, and then the signals output by the power amplifier are received and analyzed to obtain a detection result. During each detection, the connection between different input ends and corresponding cables needs to be established or disconnected manually, and the power amplifier receives signals or signal combinations. If the test quantity is large, the above operation consumes a lot of time and labor.
Based on this, this specification provides an automatic test method for power amplifier. During testing of the power amplifier, cables do not need to be plugged and unplugged, manual participation is eliminated, signals required for testing can be automatically generated, and feedback signals returned by the power amplifier are received and analyzed to obtain a testing result. The whole process is automatically finished without manual operation, and the detection efficiency is improved.
Fig. 1 is a schematic diagram of an exemplary power amplifier test system according to some embodiments of the present description. The power amplifier testing system 100 can detect the performance parameters of the power amplifier. For example, by analyzing the output of the power amplifier for multiple input signals or signal combinations, various performance parameters of the power amplifier, such as signal-to-noise ratio, distortion level, etc., are determined. As shown in fig. 1, the power amplifier testing system may include a power amplifier 110 to be tested and a detecting device 120.
The power amplifier 110 to be detected may be a power amplifier to be detected, for example, a power amplifier that is put on the market after the power amplifier is manufactured in a factory. In some embodiments, the power amplifier to be detected 110 may be a device for signal amplification applied in any field (e.g., entertainment such as audio, communication, military, etc.). In some embodiments, the power amplifier 110 to be detected may be an audio power amplifier. The power amplifier to be detected 110 may have a plurality of inputs, each of which allows a specific signal to be input. Various signals such as digital signals, analog signals, optical fiber signals, HDMI signals, etc. can be input into the power amplifier 110 to be detected through the corresponding input terminals. The signal that does not match the input terminal cannot be transmitted into the power amplifier 110 to be detected. For example, one input terminal of the power amplifier 110 to be detected only receives the digital signal. Other types of signals, such as analog signals or optical signals, cannot be transmitted from the input terminal into the power amplifier 110 to be detected. In some embodiments, each input end of the power amplifier 110 to be detected may be connected to a signal source through a cable, and after the signal source generates, the signal may be transmitted to the input end through the signal cable and then enter the power amplifier 110 to be detected. In this specification, a cable for connecting a signal source and an input terminal of the power amplifier 110 to be detected may be referred to as a signal path.
The detecting device 120 may be a device with signal generating and data processing functions, and is configured to perform performance detection on the power amplifier 110 to be detected. For example, the detection device 120 may be a computer, and functions of signal generation and/or data processing are realized by a program installed thereon. In some embodiments, the detection device 120 may generate a plurality of signals required for the detection of the power amplifier 110 to be detected based on a preset test rule (for example, set manually or generated automatically based on the type of the power amplifier 110 to be detected), and transmit the plurality of signals to the device 110 to be detected through a plurality of signal channels. The detection device 120 may have a plurality of signal outputs that may be connected to a plurality of inputs of the power amplifier 110 to be detected via signal paths (e.g., signal paths 130-1, 130-2, and 130-3). Through these signal channels, the signal generated by the detection device 120 can be transmitted to the power amplifier 110 to be detected.
In some embodiments, the detection device 120 may also receive a feedback signal returned by the power amplifier 110 to be detected. For example, the feedback signal may be transmitted from the power amplifier 110 to be detected to the detection device 120 through a cable (also referred to as a signal channel, such as the signal channel 140) connection between the output terminal of the power amplifier 110 to be detected and the signal input terminal of the detection device 120. After receiving the feedback signal returned by the power amplifier 110 to be detected, the detection device 120 may process the feedback signal based on a preset analysis algorithm/program to obtain the performance parameter related to the power amplifier 110 to be detected.
During the detection, the signal path between the power method to be detected 110 and the detection device 120 may be connected. After the connection is completed, the detection device 120 may generate a test signal according to a preset test program, and transmit the test signal to the power amplifier 110 to be detected. For example, for different performance parameters, the detection device 120 may generate different test signals and transmit the test signals to the power amplifier 110 to be detected, for example, the test signals are transmitted through the signal channels 130-1, 130-2, and 130-3 connected to the input end of the power amplifier 110 to be detected. After processing the signal for testing, the power amplifier 110 to be tested may send a feedback signal to the detection device 120 through the signal channel 140. After receiving the feedback signal, the detection device 120 performs automatic analysis/processing to obtain performance parameters related to the power amplifier 110 to be detected, and may automatically perform test recording and store the test recording in a background memory or an external memory of the detection device 120. The whole testing process is carried out automatically without human participation. The tester is not required to frequently plug and unplug the cable (for example, frequently establishing or disconnecting the signal channel) connected to the input end of the power amplifier 110 to be tested, and is also not required to manually record the test result.
Fig. 2 is an exemplary flow diagram of a power amplifier testing method according to some embodiments of the present disclosure. In some embodiments, flow 200 may be performed by a processing device. For example, the process 200 may be stored in a storage device (e.g., an onboard storage unit of a processing device or an external storage device) in the form of a program or instructions that, when executed, may implement the process 200. In some embodiments, the flow 200 may be performed by the detection device 120 shown in fig. 1. In some embodiments, the process 200 may be performed by the test system 300. As shown in fig. 2, the process 200 may include the following steps.
In step 210, a plurality of signal channels corresponding to a plurality of inputs of the power amplifier are determined. This step may be performed by the first determination module 310.
It is known that the power amplifier has a plurality of inputs connected to a plurality of signal paths, respectively, before the detection is performed. However, since the connection between the input and the signal path is performed manually, there may be a non-corresponding connection. For example, the consistent socket shape of the two inputs results in two cables being inserted incorrectly, thereby forming a signal path that does not correspond to the connection. Thus, the signal cannot be transmitted from the input terminal to the power amplifier. In some embodiments, the plurality of signal paths are randomly connected to the plurality of inputs of the power amplifier. For example, form-fitting cables are randomly inserted to form signal channels according to the socket shape of the input. Therefore, the first determining module 310 may perform a self-test after the cable is connected, and determine a plurality of signal paths corresponding to the plurality of input terminals of the power amplifier. The corresponding connection may be a connection between the input end and the signal channel, so that the signal can be smoothly transmitted from the signal source (e.g., the detection device 120, or the test system 300) to the power amplifier (e.g., the power amplifier 110 to be detected) through the signal channel.
In some embodiments, to determine a plurality of signal paths corresponding to a plurality of inputs of a power amplifier, for each of the plurality of signal paths, the first determining module 310 may determine a type of signal received by the input of the power amplifier connected to the signal path. The first determination module 310 may generate a detection signal. The detection signal may be one of a plurality of signals that are acceptable to the power amplifier (e.g., the power amplifier 110 to be detected). For example, the detection signal may be an analog signal, provided that the power amplifier may receive a digital signal, as well as an analog signal. The parameters of the detection signal may be arbitrary, for example, the amplitude/frequency/phase of an analog signal as the detection signal may be arbitrary. The first determining module 310 may then transmit the detection signal to the power amplifier through the signal path and determine whether a detection feedback signal is received. If the first determining module 310 receives the detection feedback signal, the signal type of the detection signal may be determined as the signal type accepted by the input terminal. It is known that the detection signal, if it is to be successfully received by the power amplifier, needs to pass through the correctly connected input to be received. For example, an input terminal allowing a digital signal to be input can only receive a digital signal, while an analog signal cannot be input. Thus, in another aspect, the input connected to the signal path may be considered a signal transmission gate. If the signal channel is correspondingly connected with the input end, the checkpoint is a path, and a signal can be input into the power amplifier through the input end through the signal channel. If the signal channel is not correspondingly connected with the input end, the checkpoint is closed circuit, and the signal cannot be input into the power amplifier through the input end through the signal channel. After receiving the detection signal, the power amplifier may process, e.g., amplify, the detection signal to obtain the detection feedback signal. The detection feedback signal is a signal obtained after being processed by the internal processing logic of the power amplifier. The first determination module 310 may determine whether the power amplifier receives the detection signal according to whether the detection feedback signal is received. The power amplifier will have an output only if there is an input. In this case, the first determining module 310 may determine that the signal path is a path between the input terminal of the power amplifier and the signal path, that is, the type of the detection signal generated by the first determining module 310 may be passed through the input terminal connected to the signal path. At this time, the first determining module 310 may determine the signal type of the detection signal as the signal type accepted by the input terminal.
In some embodiments, after determining the signal type received by the input terminal of the power amplifier connected to the signal channel, the first determining module 310 may determine the signal type of the detection signal as the signal type corresponding to the signal channel. Thus, the test system 300 can determine the connections between the signal paths and the inputs of the power amplifier, which are the corresponding connections (or correct connections), and can pass the signals. Meanwhile, the test system 300 may also generate and broadcast a prompt message according to whether the signal channels are correctly connected to the input terminals of the power amplifier, so as to notify an operator to change the connection between the signal channels and the input terminals of the power amplifier, so as to achieve corresponding connection between all the signal channels and all the input terminals of the power amplifier.
In some embodiments, the preset test rule may refer to a signal generation logic pre-specified according to a test requirement. For example, assume that three performance parameters A, B and C of the power amplifier need to be tested. The test A needs to input a signal a into the power amplifier, the test B needs to input a signal B into the power amplifier, and the test C needs to input a signal C and a signal d into the power amplifier. And analyzing the feedback signals of the signals according to the power amplifier to obtain the three performance parameters. Then the signal required for testing can be obtained according to the testing requirement when the above certain parameter needs to be determined. Then it may be the preset test rule that represents this logic. Therefore, which performance parameter needs to be tested in the current testing stage, the generating module 320 may generate a corresponding test signal according to the testing requirement.
In some embodiments, the test signal may comprise an electrical signal (e.g., a digital signal, an analog signal, an optical signal (e.g., a lightwave signal), etc. the type of test signal may be determined based on the type of signal that the power amplifier may accept as input, for example, the test signal may comprise only an analog signal, assuming that the input of the power amplifier is only capable of receiving an analog signal.
In some embodiments, the signal path corresponding to the test signal may refer to a signal path correspondingly connected to an input terminal receiving the test signal input. It will be appreciated that the test signal needs to be transmitted to the power amplifier after it has been generated. The transmission path may be a signal path, and the test signal is transmitted from the correct input terminal to the power amplifier. For example, if a test signal with a signal type of optical signal needs to be transmitted, the transmission module 330 may transmit the test signal from a signal channel corresponding to the input end of the fiber socket of the power amplifier.
At step 240, a test feedback signal corresponding to the test signal is obtained. This step may be performed by the acquisition module 340.
In some embodiments, the test feedback signal may be a signal that has been processed with respect to the test signal. For example, the power amplifier, upon receiving a test signal, processes the test signal, such as amplifying a relatively weak input signal (i.e., the test signal). The amplified signal may be the test feedback signal. In some embodiments, the test feedback signal may comprise a first feedback signal directly output by the power amplifier. For example, the obtaining module 340 may obtain a feedback signal transmitted by the power amplifier (e.g., the device under test 110) to the test system 300 (or the detection device 120) directly through the signal path (e.g., the signal path 140) after receiving and processing the test signal. The first feedback signal may comprise an electrical signal, e.g. an analog signal.
In some embodiments, the test feedback signal may further include a second feedback signal generated based on the first feedback signal. The first feedback signal, after being generated, may be transmitted to a third party device at the same time as being transmitted to the test system 300 (or the detection device 120). For example, assuming the power amplifier is an audio power amplifier, the first feedback signal may be simultaneously transmitted to a third party device, the audio. The first feedback signal, after being received by the speaker, may drive the speaker to emit a sound. The sound signal may be considered as said second feedback signal. In some embodiments, the second feedback signal may comprise a sound signal. The obtaining module 340 may include a pickup part to obtain the second feedback signal.
There may be a corresponding test algorithm for each performance parameter test of the power amplifier. The test algorithm may be in the form of a software program that is pre-installed onto the test system 300 (or the test device 120) and may be invoked. In this specification, the test algorithm may also be referred to as a signal detection target algorithm. Based on the foregoing, the test signal is generated based on the preset test rule, and the preset test rule reflects which performance parameter is detected. This also reflects, on the one hand, the test algorithm (the signal detection target algorithm) required to process the test feedback signal. Accordingly, the second determination module 350 may determine the signal detection target algorithm based on the preset test rule. For example, assuming that the preset test rule shows that the distortion degree of the power amplifier needs to be tested, the second determining module 350 may determine a signal detection target algorithm for detecting the distortion degree for a subsequent invocation. After determining the desired signal detection target algorithm, the second determination module 350 may process the test feedback signal directly using the signal detection target algorithm to determine the power amplifier related performance parameter. For example, the second determining module 350 may directly invoke a signal detection target algorithm for detecting the distortion level, process the test feedback signal to determine the distortion level of the power amplifier.
The power amplifier testing method disclosed in the present specification can detect the connected signal channels on all the input terminals of the power amplifier to be detected, so as to determine whether the input terminals are correctly connected. Subsequently, a test signal required for the corresponding test may be generated according to each required test item (e.g., according to a preset test rule). And transmitting the signal to a power amplifier to be detected through a corresponding signal channel. After receiving the test feedback signal of the test signal, the required signal detection target algorithm can be automatically determined, and the test feedback signal is processed by using the signal detection target algorithm to obtain a test result. In the whole test process, the connection between the input end of the power amplifier to be detected and the signal channel does not need manual connection and/or disconnection, and signal generation and processing can be automatically carried out. The detection time is effectively reduced, and the detection efficiency is improved.
It should be noted that the above description related to the flow 200 is only for illustration and description, and does not limit the applicable scope of the present specification. Various modifications and alterations to flow 200 will be apparent to those skilled in the art in light of this description. However, such modifications and variations are intended to be within the scope of the present description.
Fig. 3 is an exemplary block diagram of a test system for power amplifier testing according to some embodiments of the present disclosure. As shown in fig. 3, the test system 300 may include a first determination module 310, a generation module 320, a transmission module 330, an acquisition module 340, and a second determination module 350.
The first determination module 310 may determine a plurality of signal paths connected corresponding to a plurality of inputs of the power amplifier. The signal channel may refer to a cable for connecting a signal source (e.g., the detection device 120, or the test system 300) and an input end of the power amplifier 110 to be detected. Before the power amplifier detects, its multiple input terminals are connected with multiple signal channels. In some embodiments, the plurality of signal paths are randomly connected to the plurality of inputs of the power amplifier. The first determining module 310 may perform a self-test after the cable is connected, and determine a plurality of signal paths corresponding to the plurality of input terminals of the power amplifier. The corresponding connection may be a connection between the input end and the signal channel, so that the signal can be smoothly transmitted from the signal source (e.g., the detection device 120, or the test system 300) to the power amplifier (e.g., the power amplifier 110 to be detected) through the signal channel. In some embodiments, to determine a plurality of signal paths corresponding to a plurality of inputs of a power amplifier, for each of the plurality of signal paths, the first determining module 310 may determine a type of signal received by the input of the power amplifier connected to the signal path. The first determination module 310 may generate a detection signal. The first determining module 310 may then transmit the detection signal to the power amplifier through the signal path and determine whether a detection feedback signal is received. If the first determining module 310 receives the detection feedback signal, the signal type of the detection signal may be determined as the signal type accepted by the input terminal. After determining the signal type received by the input terminal of the power amplifier connected to the signal channel, the first determining module 310 may determine the signal type of the detection signal as the signal type corresponding to the signal channel.
The generating module 320 may generate at least one test signal based on a preset test rule. The preset test rule may refer to a signal generation logic pre-designated according to a test requirement. The test signal may include an electrical signal (e.g., a digital signal, an analog signal, an optical signal (e.g., a lightwave signal), etc. the type of test signal may be determined based on the type of signal that the power amplifier may accept as input.
The transmission module 330 may transmit the at least one test signal from the corresponding signal channel to the power amplifier. The signal path corresponding to the test signal may refer to a signal path correspondingly connected to an input terminal receiving the test signal input. For example, if a test signal with a signal type of optical signal needs to be transmitted, the transmission module 330 may transmit the test signal from a signal channel corresponding to the input end of the fiber socket of the power amplifier.
The obtaining module 340 may obtain a test feedback signal corresponding to the test signal. The test feedback signal may be a signal that has been processed with respect to the test signal. For example, the power amplifier, upon receiving a test signal, processes the test signal, such as amplifying a relatively weak input signal (i.e., the test signal). The amplified signal may be the test feedback signal. In some embodiments, the test feedback signal may comprise a first feedback signal directly output by the power amplifier. The first feedback signal may comprise an electrical signal, e.g. an analog signal. In some embodiments, the test feedback signal may further include a second feedback signal generated based on the first feedback signal. The second feedback signal may comprise a sound signal.
The second determination module 350 may determine the power amplifier related performance parameter based at least on the test feedback signal. There may be a corresponding test algorithm for each performance parameter test of the power amplifier. The test algorithm may be in the form of a software program that is pre-installed onto the test system 300 (or the test device 120) and may be invoked. In this specification, the test algorithm may also be referred to as a signal detection target algorithm. The second determination module 350 may determine the signal detection target algorithm based on the preset test rule. For example, assuming that the preset test rule shows that the distortion degree of the power amplifier needs to be tested, the second determining module 350 may determine a signal detection target algorithm for detecting the distortion degree for a subsequent invocation. After determining the desired signal detection target algorithm, the second determination module 350 may process the test feedback signal directly using the signal detection target algorithm to determine the power amplifier related performance parameter.
