1. VI curve analysis, also known as ASA, does not involve circuit principle and does not require the circuit to be in working state, so it can be used for fault detection of circuit board that are separated from equipment (without online detection) without drawing data; It is absolutely forbidden to carry out electrification and measure the undischarged capacitance. Since the circuit board does not need to be powered, the circuit board is relatively safer. It does not involve the functions of the devices on the circuit board, so no matter what type of devices the circuit is composed of, digital, analog, digital analog mixed, functional known, unknown (such as dedicated, programmable), etc., it can be tested; It is tested by circuit node (device pin), and is basically not limited by the packaging of components on the circuit board. As a single device can be regarded as the simplest circuit board, ASA technology can also be used to detect the quality of large-scale, complex or unknown integrated devices. In fact, due to limited conditions, ASA is the only way for many users to detect such devices. In addition, ASA is convenient and intuitive when it is used to detect the function of discrete components.
2. VI and multimeter resistance method type, but the multimeter resistance voltage is low, and this instrument uses AC signal to evoke circuit nodes. Because the amplitude and frequency are adjustable, the amplitude close to the working voltage can be used to evoke, and the measured graph is more real. The fault node can be found through comparison. Due to the limited current applied to the components, this technology will not affect or damage any components. ASA has many advantages, and it has been proved to be a fast and effective fault diagnosis technology.
