Analog Modulation > AM AM Settings
Item Element Description
1
Check mark indicator The check mark indicator in the upper, left-hand corner of the display shows
when the AM display is the optimized display.
2 Top of Graph Sets the %AM indicated at the top of the graph by increasing or decreasing
the vertical scale. Changing the top value affects the bottom of graph value
because the graph scales about vertical center. Also, note that the top of
graph setting interacts with the internal vertical scale setting (which is not
user settable).
3 Position Speci fi es the %AM shown at the center of the graph display.
4 Bottom Readout Displays the value of the modulation factor shown at the bottom of graph.
5 Measurement readouts
Displays numeric values for the +AM (positive modulation factor), –AM
(negative modulation factor), and Total AM.
6 Position Speci fi es the horizontal position of the trace on the graph display.
7
Scale Adjusts the horizontal range of the graph. By decreasing the scale (time
across the entire graph), the graph essentially becomes a window that you
can move over the trace by adjusting the position.
8 Clear Erases the trace from the graph.
9 Trace Detection readout Displays the Settings > Trace > Detection setting.

AM Settings
Menu Bar: Setup > Settings
Application Toolbar: Settings
The AM Settings control panel provides access to settings that control parameters of the AM Display.
Setting Description
Parameters (see page 111) Sets the Carrier Amplitude Detection method. You can choose either Average or Median.
Trace (see page 112) Sets Trace display parameters.
Scale (see page 114) Sets vertical and horizontal scale and position parameters.
Prefs (see page 115) Speci fi es whether or not certain display elements are shown. Speci fi es the maximum
number of points shown in the display graph.
