The display module 12 is used to display information according to the instructions of the control circuit board. The touch module 13 is used to provide a touch operation for the user, convert the user's touch operation into a touch electrical signal, and send the touch electrical signal to the control circuit board 11. The RedCap cellular module 14 is used to receive network signals and send network signals to the control circuit board 11. The control circuit board 11 is used to receive the touch electrical signal from the touch module 13, instruct the display module 12 to display information according to the touch electrical signal, and / or detect the quality of the network signal according to the touch electrical signal 13.

[0028] It can be understood that the control circuit board 11 is a module for controlling, judging, and processing data in the overall business process of the detection terminal, and is the core of the entire detection terminal. By integrating multiple test logics and algorithms, it realizes functions such as terminal power supply, screen display, button operation, service test setting, SIM card reading, and test data reading. The display module 12 is used to display basic information such as test data and remaining battery power. The touch module 13 is used to realize the touch function. For example, the user can select the menu in the display module or control the test process (such as starting the test and ending the test) through the touch module.

Through the third GPIO interface, switching between different SIM card modules (i.e., different SIM cards) can be realized, which is convenient for performing call testing services.

[0055] Exemplarily, as Figure 2 shown, the third GPIO interface includes pin 1 of the circuit board U21, and the fourth GPIO interface includes pin 5 of the circuit board U21.
