Figure 17-10 The CAL Gain acquisition screen
8. Move the probe back and forth over the side-drilled hole to acquire uncalibrated
peak amplitude measurement data across all focal laws.
To acquire the most accurate curve, move the probe slowly, use a guide when
possible to avoid probe skew, and make multiple passes over the reflector.
9. Choose 1/5 > PA CAL > Erase to clear the current gain curve and to redraw a new
curve.
If the yellow gain curve saturates the screen, adjust the gain to a lower value and
redraw the curve.
10. Choose 1/5 > PA CAL > Done to accept the drawn line and calculate sensitivity.
