Phased Array Calibration

This video demonstrates calibrating the Olympus EPOCH 1000i UT tester for Phased Array Operation using the IIW Type 2 Reference block. The tester display is an A-Scan and S-scan 40 degree to 70 degree sweep. The calibration is 3 parts - 1) calibrate velocity (soundpath), 2) zero (wedge delay for depth) and 3) gain (sensitivity). Note: After gain calibration the tester will display TVG (Time Varied Gain), this varies the gain amplitude depending on the distance from a reflector.
Equipment: Olympus EPOCH 1000i tester, Olympus 5MHZ 16 element PA transducer 5L16-A10P, Olympus wedge SA10P-N55S and a carbon steel IIW Type 2 Reference Block.

Hello john. Thank you for you video. So i wanna know how to switch from UT mode to the PA mode manually in the Epoch 1000i?

Thank you John. When using annex H AWS D1.1 I get quite confused with this fact of adding gain for the SSL and then adding 6dB of soft gain por scanning levels. . Adding 4dB is like calibrating for 80% instead of 50%. FSH. What would be your advice to deal with AWS requirements? Thank you again.

Hİ John
Can you show phased array tvg drawing with epoc 1000i

Hi john
I need c scan and record
Can you show c scan with epoch 1000i

In Calibration time, what will be the range & thikness?
