Beamformer Calibration

Beamformer (BF) calibration is performed to calibrate each of the two BF input's ADC channels. The

system calibrates the ADC to zero when there is no signal in the input. These bias voltages are stored

in the back end. When changing the BFs, swapping the BFs, or changing the hard disk, perform the BF

calibration procedure.

1) Access the calibration options, as described in

2) Trackball to the Calibration button and press Select. The bias voltages for each channel are

validated and stored in the back end.

If necessary, Trackball to the Validation button and press Select to validate the currently saved

bias voltages for each channel without performing calibration.
