The S-TGC delay takes values from 0 µs to 500 µs and S-TGC from - 1 to 1 dB/µs. The negative values of S-TGC help to correct not optimal TGC choice. You can apply S-TGC in the offline mode for already saved data. A1040 MIRA 3D © 2022 Acoustic Control Systems – ACS Group...

At the same time, the signals from rebars at 60 kHz have higher amplitude (sensitivity) than at 40 kHz. At 60 kHz the amplitude rises to 5 dB. A1040 MIRA 3D © 2022 Acoustic Control Systems – ACS Group...

By setting the TPS to 3.5, the second back wall becomes visible. The signal is noisy, and the shape of the indication changes with every new measurement with the same parameters. A1040 MIRA 3D © 2022 Acoustic Control Systems – ACS Group...
Page 123: Velocity Calibration
Use one of the following methods or their combination for velocity estimation. Method 1: Known sample thickness In various applications, the thickness of the inspected sample is known. Measure the velocity as follows: A1040 MIRA 3D © 2022 Acoustic Control Systems – ACS Group...
Page 124 Method 2: Automation velocity calibration The A1040 MIRA 3D and A1040 MIRA 3D PRO may estimate the sample velocity using ultrasonic wave propagating along the surface, from one DPC sensor to another.
