for the High Resolution A/D converters. This can be done individually to
make selections for different input sources to the measurement channels
(for example, the Analog Generator on Channel 1 and the Digital Generator

The following procedure explains how to select a view window to display the
measurement:
1. The View Selection Icons are shown across the top of the application window.
Select the first View to the right of the RT icon. This is View 1. Deselect all
other views so that only one view is displayed.
2. Set View 1 for a point plot if it is not. This is done in the View Setup menu that
is accessed by touching View Setup. (An alternate route to this same screen is to
press the Configure button and select View Setup.)
a. Select View 1 for configuration.
b. Enable Ch 1 Level vs. Frequency for View 1 if not enabled in the
Measurements column. This will deselect any other choice that may have
been selected.
c. In View Types select Point Plot. This provides the graphic display of X
versus Y. The Table display is very useful to supply a list of the test
frequencies and the level at those frequencies.
d. Touch Accept Changes to make the selections and return to the application
screen.
3. Press the Sweep/Run button to start the measurement sweep.
