Errors of time non-uniform and amplitude non-uniform in parallel sampling seriously influence the performance of the system.This paper established a mathematical model of parallel alternating acquisition system

and realized a normalized correction algorithm for non-uniform amplitude error.This method not only introduced programmable reference voltage source

but also corrected the offset and gain error at the same time by the method of look-up table.Finally

the calibration system estimate the time of non-uniformity parameters

which can be corrected by controlling the high precision programmable clock delay network.The correction method proposed in the thesis

after testing and verifying

is proved to increase the correction performance with high real-time performance

while reducing the design difficulty of hardware and system costs.
