| Aiming at the calibration requirements of aircraft 270V DC power supply characteristic test system, combined with GJB 5189-2003 and other relevant standards, the calibration items and methods of the test system are studied. The calibration program is written based on LabVIEW platform, which realizes the functions of standard signal generation and acquisition. A calibration device is developed based on Direct Data Synthesis, broadband precision amplification and voltage divider. The calibration system is formed，which realizes the calibration ability of steady-state parameters and transient parameters. The field verification test program is prepared. The field test of power supply test-bed is carried out. The test results show that the function and technical indexes of the calibration device meet the requirements of the test system, which verify the rationality and effectiveness of the calibration method for aircraft 270V DC power supply characteristic test system based on broadband precision amplification and voltage divider. It provides an important guarantee for the accuracy, reliability and unity of the value in the development, production and maintenance of the 270V DC power supply system of the fourth generation fighter. |
