The Phased Array “Type A” Calibration Block is used during the initial setup and calibration of a phased array ultrasonic unit. This block can be used to perform tasks such as beam angle verification, calibration for wedge delay, sensitivity calibration, performing DAC/TCG, and more. This block has similar dimensions to an IIW-Type Block, but has been specially-engineered for phased array applications.

Blocks include both 4.000" and 2.000" radii, (19) through holes at .040" diameter, (1) through hole at .080" diameter, (4) FBHs at .080" diameter x .080, .160, .235, and .315" deep, (4) FBHs at .157" diameter x .040, .120, .200, and .275" deep, (3) FBHs at .080" diameter x .120" deep machined into the 2.000" radius, and (4) EDM notches at .004, .008, .012, and .016" deep x .020" wide x 1.00" long.

Block dimensions are 1.000" thick x 4.000" tall x 12.00" long. Inch Version in accordance with PH Tool Drawing No. 10237.
