GE HEALTHCARE DIRECTION FC091194, REVISION 11 VIVID 7 SERVICE MANUAL 7 - 34 Section 7-6 - Diagnostics Tools 7-6-7-1 DC Offset Calibration DC Offset calibration also called “Beamformer Calibra tion” or “Front-End Alignment” is performed to calibrate each ADC channel of the two Beamformer (BF) board inputs. The system calibrates the Beamformer ADCs to zero output when there is no signal on the input. These bias voltages are stored on hard disk in Back-End Processor. You can either access DC Offset Calibration via the screen displayed above, or as described in Section 6-7 Front-End Alignment Procedure (Beamformer Calibration) on page 6-6 . The user interfaces are different, but they use the sa me adjustment software, so the result from the two access methodes are equal. 1.) Select DC Offset Calibration 2.) Wait for the calibration to take place. 3.) When finished, select Show Graph. NOTE: Wavy line signifies system has been calibrated. A Straight line signifies that the system has not been calibrated and can be the cause of image quality issues. NOTE: The LEDs displayed in the below individual b oard sections are relevant when the system is in the default setting (2D-mode). Figure 7-37 DC Calibration of the Beamformer AD-converters Passed
