To Output a Modulated Waveform
A modulated waveform consists of a carrier and a modulating waveform.
In AM (amplitude modulation), the amplitude of the carrier is varied by
the amplitude of the modulating waveform. For this example, you will
output an AM waveform with 80% modulation depth. The carrier will
be a 5 kHz sine wave and the modulating waveform will be a 200 Hz
sine wave.
1 Select the function, frequency, and amplitude of the carrier.
Press and then press the Freq, Ampl, and Offset softkeys to
configure the carrier waveform.
For this example, select a 5 kHz sine wave
with an amplitude of 5 Vpp.
2Select AM.
Press and then select “AM” using the Type softkey. Notice that
a status message “AM by Sine” is shown in the upper-left corner of
the display.
3 Set the modulation depth.
Press the AM Depth softkey and then set the value to 80% using the
numeric keypad or the knob and cursor keys.
