Design on Automatic Calibration System for Signal Generator Based on VEE

This paper introduces a new scheme for automatic calibration system of signal generator based on VEE aiming at the limitation of the present signal generator calibrating system.The computer controls the signal generator and measuring receiver system via GPIB bus to implement the setup of states and parameters and the collection and processing of test data for signal generator and measuring receiver system.The paper analyses the operation principle of automatic calibration system,and does a part of experiments of signal generator.The experiment results show that this system runs normally and the testing result is exact and reliable.
