摘要
为了使声学释放器水上分机能够产生对水下分机的问询信号,且保证有足够多的波形形式以满足试验所需,研制了一款任意波形发生器.该款波形发生器能够产生2路完全独立的模拟信号.其信号波形形式既可以由计算机通过USB接口配置,也可以利用触摸屏通过I2C总线,从事先固化在板卡上的串行ROM中选择.该款波形发生器可以产生不同脉宽、不同频率的方波信号激励D类功率放大器,以推动水声发射换能器,也可以产生不同填充频率的CW脉冲信号作为水上分机系统中其他单元的自检用信号.
An arbitrary signal generator was developed to enable over-water equipment of acoustic releaser to send various signals to underwater equipment, and can provide sufficient signal patterns for examination. It can offer two independent channel analog signals Signal pattern can be configured by computer via USB or selected from serial ROM on the hardware card by touch screen via I2C bug On the one hand, this type of signal generator can offer square waves with different pulse lengths and frequencies as the input of type D power amplifier to impulse the underwater acoustic sending sensor; on the other hand, it can generate CW pulse signals with different frequencies, which can be used as self-check signals for other units in over-water equipment
