An Auto-Test System Based on VEE for the Improvemet of Target Position Precision
The influence of amplitude and phase errors on precision of target position is analysed. To reduce amplitude and phase errors, iterative algorithm is applied in calibration. In this algorithm, amplitude and phase characteristics of all microwave components need to be tested.In this paper ,an auto-test system developed in VEE and based on GPIB serial bus technology is introduced. Compared with the traditional manual testing method, the anto-test system improves efficiency and accuracy on the test of digital attenuator and phase shifter with high resolution.
