Feature 1DUAL CHANNEL DISPLAY: Dual channel curve tester, showing left and right movement at the same time, can clearly compare the quality of components. 2ONLINE DETECTION: No circuit principle is involved, no need for the circuit to be in working state, and it can be used to detect circuit board faults online. 3AC EXCITATION SIGNAL: Using AC signal to excite the circuit nodes, with adjustable amplitude and frequency, and can be excited by the amplitude close to the working voltage. 4AUTO SCAN FUNCTION: The curve tester has an automatic scanning function and is often used with a dual channel oscilloscope, which is easy to operate. 5WIDE APPLICATION: Test by circuit node (device pin), not limited by the packaging of components on the circuit board, and a wide range of applications.SpecificationItem Type: Dual Channel VI Curve TesterMaterial: ABSAccessories: 2 BNC CablesProduct Description: VI curve analysis, also known as ASA, does not involve the circuit principle and does not require the circuit to be in working state, so it can be used for fault detection of circuit boards that have no drawings and data and are disconnected from the equipment (no need for online detection); no need to power the circuit board, which is relatively safer; Does not involve the function of the device on the circuit board, so no matter what type of device the circuit is composed of, digital, analog, digital analog mixed, function known, unknown (such as dedicated, programmable), etc. Test; It is tested by circuit nodes (device pins), basically not limited by the packaging of components on the circuit board. Since a single device can be regarded as the simplest circuit board circuit, ASA technology can also be used to detect the quality of large scale, complex or unknown integrated devices. In fact, due to constraints, the ASA is the only way for many users to detect such devices. In addition, when ASA is used to detect the function of discrete components, it is also convenient and intuitive. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Curve Tester2 x BNC Cables1 x USB Cable2 x AccessoriesNoteThis instrument does not have power cable.
