Sonatest Wave - 12.2.4 Amplitude Corrected and Uncorrected Measurements

Wave User Manual 61
Version 4
The figure below is based on the same previous example; however, the Gain Mode is set
to Absolute instead. The A-scan is indeed +6 dB higher, while the DAC curves have not
moved. Please note that corrected (C) measurements provide a compensated amplitude
reading. It is the advised assessment method to use for DAC amplitude measurements.
Uncorrected (U) measurements are not compensated with respect to the DAC calibration.
Figure 43 – Gain Mode is set to Absolute and 6 dB of scanning gain has been added
12.2.4 Amplitude Corrected and Uncorrected Measurements
You may choose corrected and uncorrected measurements for the amplitude DAC. They
appear as (C) and (U) in the top measurement bar, within a drop-down list.
