Calibrating the EPOCH 1000 Series (Phased Array Mode) 301
Figure 17-23 The Gain acquisition screen
8. Move the probe forward and backward 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. Make multiple passes over the reflector.
9. Choose 1/5 > PA Cal > Erase to clear the current gain curve and redraw a new
curve.
When 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.
