| Abstract: | The signal with high frequency and amplitude modulation by PC programming is sent to HP33120A Arbitrary Function Generator through RS232 serial port and IEEE488 parallel port. HP33120A Arbitrary Function Generator receives and processes the signal, then outputs the needed signal for exciting ultrasonic guided waves. The data communication between PC and HP33120A generator through RS232 serial port and IEEE488 parallel port is lucubrated and the adjustability of frequency and period of the signal is emphasized. The real arbitrary waveform generator that can generate single acoustic frequency signal modulated by Manning window and Gaussian window is developed. |
