Forum Post: RE: Testing beamformer IC

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 acoustic wave velocity in the human body)

S - penetration depth (practically 2-24cm)

For beamformer testing purposes you can use just only 2 voltages 1.8V and 3.3V.

Good luck,

Mariusz
