Daily status monitoring of CP testing equipment is also an important task. However, some CP testing equipment still uses complex and cumbersome methods for testing, or lacks status monitoring functions altogether. This can lead to the testing equipment being out of control, making it impossible to detect and contain problems in a timely and effective manner.

[0003] Therefore, how to research and design a multifunctional detection device that can overcome the above-mentioned defects is an urgent problem we need to solve. Utility Model Content

[0009] The output terminal of the BNC interface circuit is connected to the common polarity interface of the test equipment;

[0010] The output terminal of the DB37 interface circuit is connected to the interface of the DUT circuit of the test equipment.

[0011] Compared to existing technologies, some CP testing equipment still employs complex and cumbersome testing methods or lacks status detection capabilities. This can lead to the testing equipment being out of control, making it impossible to promptly and effectively identify and address problems. This invention provides a multifunctional testing device. Using this solution, daily monitoring of the testing equipment status improves efficiency while reducing the risk of CP test data distortion, and allows for timely detection and correction of data distortion. Specifically, the solution includes a protection resistor circuit, an FT sample tube circuit, a BNC interface circuit, and a DB37 interface circuit. The protection resistor circuit primarily serves as a current-limiting protection, effectively reducing the risk of FT sample tube breakdown during continuous testing. Its input is connected to the pins of the FT sample tube circuit, and its output is connected to the BNC and DB37 interfaces. The FT sample tube circuit, the core component for implementing the testing function, connects to the tester interface via the DB37 interface circuit to perform the testing.

[0012] Specific working principle: After the BNC interface and DB37 interface are connected to the tester, a test loop is formed with the tester's DUT circuit, thereby implementing a simulated testing environment. When the tester is testing, the output will be sent through the test DUT, through the testing device, and back to the tester DUT, thus realizing the tester's testing function and facilitating quick self-testing of the tester's status.

The BNC interface circuit is mainly composed of multiple soldered BNC sockets, and this part is used to lead out the common polarity interface wiring and connect it to the common polarity interface of the tester.

[0016] To protect the circuits and PCB substrate, a housing is also included, which has a cavity inside, and the PCB substrate is located inside the cavity.

[0017] To position and secure the PCB substrate, the housing has several fixing holes, and the PCB substrate is fixedly connected to these fixing holes. Fixing elements can be installed on the fixing holes for detachably securing the PCB substrate.

[0018] To facilitate the wiring of the BNC interface circuit output terminal, the housing is also provided with several wire holes for wiring to pass through the housing.

[0019] To facilitate the DB37 interface extending out of the housing and to prevent the DB37 interface from becoming loose during use, the housing is also equipped with a DB37 mounting hole, the size of which is adapted to the DB37 interface; the DB37 interface is used to insert into the DB37 mounting hole and extend out of the housing.

[0020] To facilitate immediate inspection and disassembly of related hardware, the housing is also equipped with a magnetic access port. The addition of magnetism effectively prevents the magnetic access port from moving freely during use and affecting its functionality.

[0021] The housing is made of acrylic material to facilitate observation of the interior through the transparent sidewalls.
