| Abstract: | Generally, the developing period of traditional instrument is longer. Its precision is low and cost is high. Virtual instrument technology can simulate the faceplate of traditional instrument on the screen of computer, and the testing results can be given by different ways. Virtual instrument can finish digital signal calculation, analyzing and processing with software; and complete signal collection, testing and debugging with input/output (I/O) interface. It is a kind of computerization instrument system that has a lot of testing functions. A digital ultrasonic detector faceplate and some functions were designed and constructed with software LabVIEW. |
