Hi Fathima,Testing is very easy. Just generate a FIRE signal (TX_EN). For medical ultrasound applications the pulse repetition frequency should be calculated as follows: PRF=V/(2*S)V=1560m/s (mean...

Hi Chuck,Well, I also can't find :))) According to Chandu's question I have simply assumed that such a term must be in the datasheet. Sorry for false alarm.Best Regards,Mariusz
