Figure 11-7 The completed DAC curve
Once the DAC curve is complete and the instrument is in inspection mode, the
instrument provides a new set of parameters:
TVGView (DAC View)
This function allows you to toggle between the DAC curve acquired and the
corresponding TVG setup based on the DAC curve information.
Curve Gain
This adjustment allows you to manipulate the screen height/gain of both the
DAC/TVG curve as well as the echoes on screen. This allows for amplitude-to-
curve comparison at code compliant screen levels across the time base.
∆ Curve dB
This setting controls the steps by which Curve Gain is adjusted. Possible steps are
0.1, 1.0, 2.0, 3.0, 6.0, 12.0 dB.
Next DAC
This function cycles through the available DAC curves (if more than one is
available) for amplitude comparison with on-screen echoes.
