Abstract

This system is an intelligent instrument,which uses CPLD,MCU,with digital circuitry and analog circuitry to make measure precision of phase and frequency beyond demand of design. All kinds of measurement data and parameters in this system can be displayed through the LCD. LCD's extended function is that display calendar and time and it can work if the system's power is lost. All these functions added friendly capability of man-machine interface. This system adopts the best plan so it can overcome disadvantages of CPLD and MCU and other electron elements functions. and accomplishes the desire of design and beyond it,and has good stabilization and anti-jamming function.
