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.

Thanks for this video. Very helpful!
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?
Hİ John Can you show phased array tvg drawing with epoc 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.
In Calibration time, what will be the range & thikness?
Hi john I need c scan and record Can you show c scan with epoch 1000i
А на русском языке, перевод есть?
