If you need to continue capturing points, you can increase the instrument range or
increase the display delay to view echoes further out in time.
Once the correct number of points have been captured, choose DAC/TCG > Done to
complete the DAC curve and switch to the DAC inspection mode.
Once the DAC curve is complete and the instrument is in inspection mode, the
instrument provides a new set of parameters:
• DAC Gain
This adjustment allows you to manipulate the screen height/gain of both the
DAC/TCG curve as well as the echoes on screen. This allows for amplitude-to-
curve comparison at code compliant screen levels across the time base.
• View
This parameter allows you to toggle between the DAC curve acquired and the
corresponding TCG setup based on the DAC curve information.
