Taking the computer motherboard frequency range test as an example, the general test method usually uses manual test, that is, the user first adjusts the frequency generator according to the frequency range to be tested to generate a minimum frequency value in the frequency range, and the frequency generator again The frequency is output to the motherboard, and then the user powers on the motherboard. After the motherboard is powered on, the user starts a test software to test whether the motherboard can run normally at this frequency, and then gradually increases the frequency value and cyclically performs the above test operation. The test result is obtained until the maximum frequency value in the frequency range is tested.

Whether the various components can work normally, and after the test device is tested, the test results of whether the components can work normally are read. If the test results are recorded as the components can work normally, a shutdown signal is sent to make the standby The measuring device is turned off; and a frequency adjusting module is configured to determine whether the test frequency is greater than or equal to a maximum value of the frequency test interval to determine whether the test frequency exceeds the frequency test interval, and if the test frequency is not greater than or equal to the frequency test The maximum value of the interval, after the device under test is turned off, the test frequency of the device under test is added to a preset frequency constant to form another adjusted frequency value, which is transmitted to the frequency generator for testing the next frequency. Another frequency adjustment value is transmitted to the frequency generator to cause the frequency generator to generate a corresponding test frequency signal to be output to the device under test.

A preferred embodiment includes a test device 10, a monitor 16, and a frequency. The generator 20 and a power source 30. The test device 10 can be a computer, a server, or the like. The device under test 40 can be a computer motherboard or the like.

The test device 10 is connected to the frequency generator 20 through a USB (Universal Serial Bus) data line, connected to the device under test 40 via a network route, and connected to the monitor 16 and the power source 30. The frequency generator 20 and the power source 30 are also connected to the device under test 40. In other embodiments, the test device 10 is not limited to being connected to the frequency generator 20 via a USB data line, nor is it limited to being connected to the device under test 40 via a network route.

The test device 10 includes a frequency setting module 102, a power control module 104, a determining module 106, a detecting module 108, a frequency adjusting module 110, and a display module 112.

The frequency setting module 102 is configured to receive a frequency test interval set by a user, such as [1 GHz, 10 GHz], and set a minimum value of the frequency test interval as an initial adjustment frequency value to be written to the frequency generator 20. In other embodiments, the frequency setting module 102 may also write the maximum value of the frequency test interval as the initial adjustment frequency value to the frequency generator 20.

The frequency generator 20 is configured to generate a corresponding test frequency according to the written adjusted frequency value. Rate the signal and output the generated test frequency signal to the device under test 40.

The power control module 104 is configured to control the power source 30 to supply power to the device under test 40.

The determining module 106 is configured to determine whether the device under test 40 can be powered on normally under the test frequency signal. After the device 40 is powered on, a response signal is sent to the determining module 106 of the testing device 10. The determining module 106 sets a time period (for example, 2 seconds), and the time is started after the device under test 40 is powered on. If the determining module 106 receives the response signal sent by the device under test 40 during the timeout period, it is determined that the device under test 40 can be normally turned on at the test frequency.

The detecting module 108 is configured to determine whether components of the device under test 40, such as a hard disk drive, a memory, a CPU, etc., can work normally to determine whether the device under test 40 is working properly at the test frequency. The specific working process of the embodiment is: after the detecting module 108 knows that the device under test 40 can be normally turned on, it sends a test software command to the device under test 40 to start a test software on the device under test 40 to start testing. Whether the components on the device to be tested can work normally, and the test device 40 saves the test result indicating whether the components can work normally after the test. The detection module 108 sets a test time. After the detection module 108 sends the start test software command and reaches the test time, the test result is read from the device under test 40, and if the test result is recorded as When the components can work normally, a shutdown signal is sent to turn off the device under test 40. If the test result records that a component is not working properly, the power supply control module 104 controls the power supply 30 to power off the device under test 40. For example, when the test software on the device under test 40 tests whether the CPU on the device under test 40 can work normally, an algorithm may be preset in the test software to allow the CPU to execute. If the CPU executes and gives a correct result, It means that the CPU can work normally, otherwise it means the CPU is not working properly.

The frequency adjustment module 110 is configured to determine whether the test frequency is greater than or equal to the maximum value of the frequency test interval. If the test frequency is not greater than or equal to the maximum value of the frequency test interval, the device under test 40 is to be tested after the device under test 40 is powered off. The test frequency is added to a preset frequency constant (such as 100MHz) to form another adjusted frequency value and transmitted to the frequency generator 20 for the next frequency test. If the test frequency is greater than or equal to the maximum value of the frequency test interval, it indicates that After testing all the values in the frequency test interval, the monitor 16 is caused to display the corresponding test result through the control display module 112. In other embodiments, if the initial adjustment frequency value is the maximum value of the frequency test interval, the frequency adjustment module 110 determines whether the test frequency is less than or equal to the minimum value of the frequency test interval, and if not, shuts down the device under test 40. Thereafter, the test frequency of the device under test 40 is subtracted from a predetermined frequency constant (eg, 100 MHz) to form another adjusted frequency value, which is transmitted to the frequency generator 20 for testing of the next frequency.

As shown in FIG. 2, the frequency range test method of the present invention is used to test whether the device under test 40 can work normally in a set frequency range. The preferred embodiment includes the following steps: Step S100, the frequency setting module 102 receives A frequency test interval set by the user, and the minimum value of the frequency test interval is written as the initial adjustment frequency value to the frequency generator 20.

In step S102, the frequency generator 20 generates a corresponding test frequency signal according to the written adjusted frequency value, and outputs the generated test frequency signal to the device under test 40.

In step S104, the power control module 104 controls the power supply 30 to supply power to the device under test 40.

In step S106, the determining module 106 determines whether the device under test 40 can be normally turned on under the test frequency signal, that is, receives the response sent by the device under test 40 within the timeout period. If the signal is determined, the device under test 40 can be normally turned on at the test frequency, and step S108 is performed. Otherwise, it is determined that the device under test 40 cannot be turned on at the test frequency, and step S110 is performed.

In step S108, the detecting module 108 determines whether the components on the device under test 40 can work normally, that is, sends the test software to the device under test 40 to start a test software command, so that a test software on the device under test 40 starts testing. Whether the components on the device can work normally, and when the test time is reached, the test result is read from the device under test 40. If the test result is recorded as the components can work normally, step S112 is performed, if the test result is When it is recorded that a certain component cannot work normally, step S110 is performed.

In step S110, the power control module 104 controls the power supply 30 to stop supplying power to the device under test 40, and step S118 is performed.

In step S112, the detection module 108 sends a shutdown signal to the device under test 40 to cause the device under test 40 to be powered off.

In step S114, the frequency adjustment module 110 determines whether the test frequency is greater than or equal to the maximum value of the frequency test interval. If the test frequency is greater than or equal to the maximum value of the frequency test interval, step S118 is performed, if the test frequency is not greater than or equal to the frequency test interval. The maximum value is executed in step S116.

In step S116, the frequency adjustment module 110 adds the test frequency of the device under test 40 to a preset frequency constant to form another adjustment frequency value, and returns to step S102.

In step S118, the frequency adjustment module 110 controls the display module 112 to cause the monitor 16 to display corresponding test results, such as "cannot be turned on at 50 GHz" or "test pass".

The frequency range test system and method of the present invention can automatically test the frequency of the device under test 40 to determine whether the device under test 40 can work normally within a set frequency range, thereby improving test efficiency.
