Detailed Description
Preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, this example provides a parallel testing method for dual-frequency multi-antenna devices under test, including the following steps:
step S1, creating a first thread and a second thread, and controlling a 2.4G chip and a 5G chip of the device to be tested to simultaneously send signals through the first thread and the second thread after the test is started;

The first thread is used for controlling a 2.4G chip of the equipment to be tested to send signals, and the second thread is used for controlling a 5G chip of the equipment to be tested to send signals; or the first thread is used for controlling a 5G chip of the equipment to be tested to send signals, and the second thread is used for controlling a 2.4G chip of the equipment to be tested to send signals. That is to say, the first thread and the second thread are instruction threads issued by the testing computer network cable, and are respectively used for controlling the device to be tested to transmit a signal in a 2.4GHz frequency band or a signal in a 5GHz frequency band. In this example, in step S3, the test instrument analyzes the 2.4GHz band signal or the 5GHz band signal received after the first thread or the second thread is completed.
In step S2 in this example, the test instrument at the receiving end sequentially acquires the signal of the 2.4GHz band of the 2.4G chip and the signal of the 5GHz band of the 5G chip. As shown in fig. 1, step S2 in this example includes the following sub-steps:
step S201, the test instrument at the receiving end judges whether the signal transmission of the 2.4G chip is finished, if so, the step S3 is skipped to analyze the received signal of the 2.4GHz frequency band, and if not, the step S202 is skipped to;
step S202, the test instrument at the receiving end judges whether the signal transmission of the 5G chip is finished, if so, the step S3 is skipped to analyze the received signal of the 5GHz frequency band, and if not, the step S201 is returned to.
Correspondingly, as shown in fig. 1, after the step S201 goes to the step S3, the step S3 in this embodiment includes the following sub-steps:
step S301, starting to analyze the received signals of the 2.4GHz frequency band through a test instrument, and waiting and acquiring the signals of the 5GHz frequency band simultaneously;
step S302, until the 5G chip sends the signal, analyzing the received signal of the 5GHz frequency band.
As shown in fig. 1, after the step S202 goes to the step S3, the step S3 in this example includes the following sub-steps:
step S301', the received 5GHz band signal is analyzed by a test instrument, and meanwhile, the 2.4GHz band signal is waited and collected;
step S302', until the 2.4G chip sends the signal, the received signal of the 2.4GHz frequency band is analyzed.
As shown in fig. 2, this example further provides a parallel test system for dual-frequency multi-antenna devices to be tested, which adopts the parallel test method for dual-frequency multi-antenna devices to be tested, and includes: the device comprises a test computer, a power divider and a test instrument, wherein the test computer is connected with equipment to be tested, a 2.4G chip and a 5G chip of the equipment to be tested are respectively connected with the power divider, and the power divider is connected with the test instrument. In fig. 2, a1 and a2 are antennas of 2.4G chips, and B1 and B2 are antennas of 5G chips.
The testing computer is connected with the equipment to be tested through a network cable and issues an instruction to control the equipment to be tested to send a radio frequency signal through the network cable; and the 2.4G chip and the 5G chip of the device to be tested are respectively connected to the power divider through the antennas to realize the combination, and then are connected to the test radio frequency port of the test instrument through the radio frequency line. The 2.4G chip and the 5G chip of the device to be tested are respectively connected to the power divider through the antennas to realize combination, and a combined signal comprising two frequency bands is combined.
The difference between the prior art and the present embodiment in the time required for testing the dual-frequency multi-antenna device under test is shown by way of example; take the example of testing the A1 antenna for a 2.4G chip and the B1 antenna for a 5G chip.
In the prior art, for testing a device to be tested of a dual-frequency multi-antenna, test time T1 = T21 + T22 + T51 + T52 required for testing an a1 antenna of a 2.4G chip and a B1 antenna of a 5G chip, where T21 is time for controlling the device to be tested to transmit a signal in a 2.4GHz band, T22 is time for controlling the device to be tested to acquire and analyze a signal in a 2.4GHz band, T51 is time for controlling the device to be tested to transmit a signal in a 5GHz band, and T52 is time for controlling the device to be tested to acquire and analyze a signal in a 5GHz band, so that time for testing 1 2.4G frequency point and one 5G frequency point is T21 + T22 + T51 + T52.
The parallel test principle of this example is based on the following 2 conditions: the 2.4G chip and the 5G chip of the router type equipment to be tested are separated and can work simultaneously; and secondly, signals of 2.4GHz frequency bands and signals of 5GHz frequency bands belong to different frequency bands, and after the one-path combined signal is synthesized through the power divider, the signals of two different frequency bands of the one-path combined signal are not influenced by each other. Therefore, the 2.4G chip and the 5G chip in the same device to be tested can simultaneously send signals by creating the first thread and the second thread, and the testing instrument can sequentially collect and analyze the signals of the 2.4GHz frequency band and the signals of the 5GHz frequency band, so that the control time of the device to be tested of one frequency band can be saved.
As shown in fig. 3, the time t21 for controlling the device under test to transmit the signal of the 2.4GHz band and the time t51 for controlling the device under test to transmit the signal of the 5GHz band in this example are executed in parallel by the parallel first thread and second thread, so they are parallel in time. That is, for the device under test of the dual-frequency multi-antenna, the total test time required for testing the a1 antenna of the 2.4G chip and the B1 antenna of the 5G chip in this example is T2 = Max (T21, T51) + T22 + T52, where Max (T21, T51) represents the larger one between the two numbers of T21 and T51.
Therefore, compared with the existing test mode, the time saved by this example is T1-T2 = (T21 + T22 + T51 + T52) - (Max (T21, T51) + T22 + T52) = Min (T21, T51), where Min (T21, T51) represents the smaller one between the two numbers of T21 and T51. In summary, in any pair of test items of the device under test supporting the dual-frequency multi-antenna of the 2.4G chip and the 5G chip, the test time that is shorter than the test time that is t21 for controlling the device under test to transmit the signal in the 2.4GHz band and t51 for controlling the device under test to transmit the signal in the 5GHz band can be saved in this embodiment. For the dual-frequency multi-antenna device under test with a large number of antennas and a large number of test items, the saved Min (t21, t51) test time is accumulated to be very considerable.
In the embodiment, the parallel test of the 2.4G chip and the 5G chip in the same device to be tested is realized by establishing the first thread and the second thread, so that the test time required by the device to be tested with double-frequency and multiple-antenna is saved, and the production efficiency is improved; it is worth to be added that the parallel test described in this example means that signals in 2.4GHz band and signals in 5GHz band of different bands in the same device under test are reasonably tested simultaneously, and if the parallel test is combined with parallel tests among a plurality of devices under test, the effect is more obvious, which is very considerable for mass industrial production.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
