As shown in the figure, the measuring jig 1000 is suitable for being inserted into the first slot 2200 of the motherboard 2000 . The measuring fixture 1000 includes a first connection end 1200 , a second connection end 1400 and a processing unit 1600 . The first connection end 1200 is pluggable and inserted into the first slot 2200 . The second connection end 1400 is pluggable and inserted into the first slot 2200'. The processing unit 1600 is electrically connected to the first connection end 1200 and the second connection end 1400 . The motherboard 2000 has, for example, a first socket 2200 , a second socket 2600 , an electronic component 2400 and a control unit 2800 . The first slot 2200 or the first slot 2200' is electrically connected to the second slot 2600 and the control unit 2800.

The first slot 2200 or the first slot 2200' is, for example, a related interface of the Peripheral Component Interconnect (PCI) or a related interface of the Peripheral Component Interconnect Express X1 (PCI-E X1) version. In one embodiment, the first connection end 1200 and the second connection end 1400 are different. The first connection end 1200 and the second connection end 1400 are, for example, the relevant interfaces of the external connection standard or the relevant interfaces of the X1 version of the shortcut external connection standard, respectively. The second socket 2600 is, for example, a socket of a central processing unit (CPU). The processing unit 1600 is, for example, a microcontroller (micro control unit, MCU), an application-specific integrated circuit (application-specific integrated circuit, ASIC), or a field-programmable gate array (Field-programmable gate array, FPGA). The control unit 2800 is, for example, a south bridge chip or a north bridge chip of the motherboard 2000 . The electronic component 2400 is, for example, a pulse width modulation integrated circuit (PWM IC) or a related circuit for generating a clock signal or a control signal. The above is only an example, but is not limited in practice.

In the following, the first slot 2200 and the first connection end 1200 are used as the relevant interfaces of the external connection standard, and the first slot 2200 ′ and the second connection end 1400 are the related interfaces of the X1 version of the shortcut external connection standard for description. . In other words, in the embodiment corresponding to FIG. 1 , the first socket 2200 and the first connection end 1200 are related interfaces of external connection standards, and the measuring jig 1000 is electrically connected to the motherboard 2000 through the first socket 2200 . In the embodiment corresponding to FIG. 2 , the first socket 2200' and the second connection end 1400 are related interfaces of external connection standards, and the measurement fixture 1000 is electrically connected to the motherboard 2000 through the second connection end 1400.

When the first connection end 1200 is inserted into the first slot 2200 or the second connection end 1400 is inserted into the first slot 2200 ′, the processing unit 1600 is used to pass through the first slot 2200 or the first slot 2200 ′ The control signal is sent to the control unit 2800 of the motherboard 2000 to instruct the control unit 2800 to control other components of the motherboard 2000 . The embodiments corresponding to FIG. 1A and FIG. 1B will be described later. In one embodiment, the processing unit 1600 instructs the control unit 2800 to control the electronic components 2400 on the motherboard 2000 via the first socket 2200 to supply power, provide a clock signal, or provide a control signal to the second socket 2600 .

Under the above-mentioned structure, the second socket 2600 can also be provided with another type of second measuring jig to measure whether the voltage levels on the contacts in the second socket 2600 meet the requirements. Therefore, in another embodiment, the first socket 2200 is electrically connected to the second socket 2600 through a channel on the motherboard 2000 or a transmission channel bridged by other components. When the measuring jig 1000 instructs the control unit 2800 to control the electronic components 2400 on the motherboard 2000 to supply power to the second slot 2600 , the second measuring jig on the motherboard 2000 measures the relevant results and communicates with the above-mentioned through the second slot 2600 . The channel of 1 transmits a feedback signal to the first slot 2200 , so that the measurement jig 1000 receives the feedback signal through the first slot 2200 . The aforementioned channel is, for example, a system management bus (SMbus), but not limited thereto. In another embodiment, the measurement jig 1000 also generates a measurement result about the second slot 2600 according to the received feedback signal. The measurement result, for example, indicates whether a short circuit or an open circuit occurs in the relevant line of the second slot 2600, but is not limited thereto.

In addition, the processing unit 1600 can perform more detailed judgment according to the received feedback signal. In one embodiment, the processing unit 1600 also judges whether the variation of the voltage level on the relevant pin is within a tolerable range or standard, so as to determine whether the relevant circuit is abnormal. For example, the processing unit 1600 can determine whether the voltage level on the relevant pin is greater than a predetermined upper limit or less than a predetermined lower limit. Alternatively, the processing unit 1600 can determine whether the voltage level on the relevant pin is pulled back to the desired voltage level within a preset time. Or, the processing unit 1600 can determine whether the average voltage on the relevant pin within a predetermined period of time meets the requirements. In fact, corresponding to the type of the signal received by the second slot 2600, such as a pulse width modulation signal or a DC voltage signal, the processing unit 1600 can perform corresponding analysis and judgment. The above is only an example, and the processing unit 1600 does not limit how the processing unit 1600 performs the determination according to the voltage level on the relevant pin.
