4 Move down a level verify that “SINE” is selected.

For the modulating waveform, you can select a sine, square, triangle,

ramp, noise, or arbitrary waveform. For this example, you will modulate

the carrier with a sine waveform. Notice that the

AM annunciator flashes,

indicating that the displayed parameter is for

AM.

SINE

Enter 5 Save the change and turn off the menu.

The modulating waveform is now a sine waveform.

ENTERED

Shift Freq 6 Set the modulating frequency to 200 Hz.

Notice that the

AM annunciator flashes, indicating that the displayed

frequency is the modulating frequency. Also notice that the modulating

frequency is displayed with fewer digits than the carrier frequency.

MOD 200.0 Hz

This message appears on the display for approximately 10 seconds.

Repeat this step as needed.

Shift Level 7 Set the modulation depth to 80%.

Notice that the

AM annunciator flashes, indicating that the displayed

percentage is the

AM depth (also called percent modulation).

080 % DEPTH

This message appears on the display for approximately 10 seconds.

Repeat this step as needed.

At this point, the function generator outputs the

AM waveform with the

specified modulation parameters.
