gain added.
Figure 11-12 Standard DAC with scanning gain off
When reference correction is active, the digital comparison between a captured
reflector and the DAC curve is accurate even with the scanning gain applied to the
inspection, provided that the gated echo is not saturated. Figure 11-13 on page 167
shows the same setup as above but with reference correction active. Notice that the
scanning gain has been removed from the dB-to-curve measurement in the
measurement reading 5 box. The instrument compares the echo height to the DAC
curve, compensates for the added scanning gain, and reports the true-amplitude
comparison.
