AM annunciator
flashes, indicating that the displayed parameter is for
AM.

5 Save the change and turn off the menu.
The modulating waveform is now a sine waveform.

6 Set the modulating frequency to 200 Hz.
Notice that the
AM annunciator flashes, indicating that the displayed
frequency is the modulating frequency for
AM. Also notice that the
modulating frequency is displayed with fewer digits than the carrier
frequency. For more information on editing numbers in the menu,
refer to “Menu Example 3” earlier in this chapter.
