Features: VI Curve Analysis (ASA): No need for circuit principles or a powered state, allowing for fault detection on separated circuit boards without requiring data. It is vital not to proceed if the capacitance is undischarged to prevent damage. Safety: Testing does not require power to the circuit board, ensuring safety. It is compatible with any types of circuit devices, whether digital, analog, or mixed. Versatile Testing: Tests are executed via circuit nodes (device pins), unrestricted by component packaging. It's ideal for large-scale, complex devices and known or unknown integrated devices. User-Friendly: ASA is the preferred method under restrictive conditions for inspecting device quality and offers an intuitive assessment of discrete components' functions. Advanced Fault Detection: Utilizes an AC signal to engage circuit nodes, providing adjustable amplitude and frequency close to working voltage for realistic graphs and fault comparisons, without harming components. Proven Technology: ASA is fast and efficient in diagnosing faults.
