Most of the traditional measuring instrument were designed and implemented by complicate hardware circuit. It made the product very expensive, thin functional and terrible big body, which limited the usage and precision of the instrument. Nowadays more and more new powerful measuring instruments are made for more accurate measurement, the kernel of most instruments are made of special computer with appropriative software and hardware, so the price is higher than before, can't be accepted by common users. In order to solve the antinomy, we bring out a challenging solution, this solution is based on PC — personal computer, the most popular computing devices in the world, we make good use of the computing technique and universal serial bus platform with bits of hardware, user can acquire a modern measuring instrument which is powerful, flexible and low price. Because this kind of instrument hasn?t specific physical status, most of its functions are implemented by software with good algorithms; it has a favorable price compared with other instrument. We called it virtual instrument. With this foundation, we made our instrument have the ability to learn by the method of engineering mathematics, and made a progress in system measure range and measurement accuracy. In the laboratory, we made a virtual measure instrument to implement a transistor measuring system, and get a notable result. Proof by facts, this solution has a good value for spreading.
