Abstract :
A synchronized sampling controller based on direct digital synthesis was developed in NIM China. It´s used in the transfer standard for harmonic measurement. The working fundamental frequency of the controller is 45 to 65 Hz; the trigger output frequency is 11.5 kHz to 16.6 kHz due to the 256 times of the fundamental frequency. The resolution of the controller is less than 1 μHz.
