Phased Array "Type A" calibration wedge
The Phased Array "Type A" calibration block is used during the initial set-up and calibration of a multi-element ultrasonic unit.
This block can be used to perform tasks such as beam angle verification, wedge delay calibration, sensitivity calibration, DAC/TCG execution, etc.
The block has similar dimensions to a Type IIW block, but has been specifically designed for multi-element applications.
