The problems existed in the calibration based on indexs given for airborne ATE are analysed,On the basis of characters of ATE,the principles and gists of the indexs are brought forward and assure the measurement and calibration for ATE effience and accuracy.
The paper is written when testing to signal in digital oscilloscope measurement and calibration and the actual application,Choose the difference bandwidth 、Sampling rate 、Sampling mode 、The interpolation mode and opening different number of channels,To the calibrate and test the result effect.
The design idea of the measurement and calibration system used in aeronautic ATE based on VXI-GPIB bus is introduced. The main characters in the design of hardware and software are described and the methods of settling technological questions are put forward.
The accuracy of the measurement and calibration of the test fixture has been demonstrated by measuring the shear modulus of two plastic (polyvinyl chloride (PVC) and urethane).
This instrument possesses three cells for measurement and calibration.
A photon counting technique is used for light measurement and calibration is by reflection of the incident beam from an ideal diffusing screen.
International comparisons as a tool for confirming the measurement and calibration capabilities of national metrological institu
We proposed principles of construction and the structure of a three-channel microprocessor system, which allows us to automatize processes of measurement and calibration, improve sensitivity, and extend the measurement range.
