This paper presents a testing method for infrared radiation characteristics of the aircraft exhaust system. By using graphical programming language of virtual instrument development testing platform, infrared radiation characteristics of jet aircraft are studied. Infrared radiation can be achieved, displayed and so on. The virtual panel and block diagram are designed. The system designed mainly is...
The current-splitting architecture for the current-steering DAC can reduce the area of the current source array greatly. A background calibration technique for current-steering digital-to-analog (DAC) with the current-splitting array is presented. The proposed calibration technique can eliminate mismatch errors for both the upper bits array and the lower bits array in the background. A 14-bit current-steering...
Very low frequency sound waves are becoming more and more widespread in underwater sound application, but the calibration on the very low frequency sound wave equipment-the sound source level of very low frequency acoustic source is very difficult, especially in shallow water environment. The propagation loss method can be used on the calibration of very low frequency acoustic source: when very low...
