Options:
|
|
DAC / TCG Option |
Multiple Curve DAC (Distance Amplitude Curve) / TCG (Time Corrected Gain) for echo amplitude adjustment and evaluation, 40 dB dynamic range, 12 dB/ μs slope, record up to 16 points, recorded points are individually editable, new points can be inserted. Display four additional curves based upon dB offset feature from originally recorded DAC curve. TCG attenuation and transfer correction features enable use on other materials and surface conditions |
IF (Interface) Gate Option |

The ERS (Equivalent reflector size) function automatically calculates the corresponding equivalent reflector diameter in mm or inches for any echo in the measurement gate |
BEA Backwall Echo Attenuator Option |
Allows independent gain control of the region under Gate B for backwall echo monitoring |
