Analysis and Evaluation of Pulse Rise Time Uncertainty in the Metrology Support for Aviation Equipment

Abstract

The pulse signal is an important basic parameter in metrology support for aviation equipment, and the calibration device of oscilloscope calibrator is an important standard for measuring the rise time of pulse signal. The composition of the measurement standard for oscilloscope calibrator is introduced, the measurement method of high speed pulse rise time is analyzed, and the uncertainty of the measurement results is evaluated.The results show that the measurement uncertainty can be reduced by setting a smaller time base and increasing the equal input power of the pulse. The uncertainty analysis of the pulse rise time can be used as a reference for compiling the measurement standard report and uncertainty analysis of oscilloscope calibrator in aviation test and calibration.
